La lesión del manguito rotador es una causa importante de dolor y disfunción del hombro. El tratamiento de las roturas masivas e irreparables del manguito rotador sigue siendo un gran reto para los ortopedistas por su complejidad y severidad. Una de las alternativas prometedoras para su manejo es el uso del balón subacromial. Presentamos el caso de una mujer de 67 años con diagnóstico de rotura masiva e irreparable del manguito rotador en el hombro derecho (grado III de Patte, grado IV Goutallier y grado II de Hamada) sin artrosis glenohumeral, tenosinovitis del bíceps y subescapular íntegro. La escala de constant preoperatorio fue de 40 puntos. Se realizó una reparación parcial artroscópica del tendón supraespinoso e infraespinoso asociado a una tenodesis suprapectoral del bíceps y la colocación del balón subacromial. La paciente realizó rehabilitación con mejoría de los arcos de movilidad, disminución del dolor e incremento de la fuerza del hombro derecho. La escala de constant postoperatorio fue de 80 puntos a la semana doce. El balón subacromial es una buena alternativa de tratamiento para las lesiones irreparables del manguito rotador con resultados óptimos a corto plazo en cuanto a dolor y función.
The rotator cuff injury is a significant cause of shoulder pain and dysfunction. Treating massive and irreparable rotator cuff tears remains a major challenge for orthopedists due to their complexity and severity. One promising alternative for managing these cases is the use of subacromial balloons. In this study, we present the case of a 67-year-old woman diagnosed with a massive and irreparable rotator cuff tear in her right shoulder (Grade III Patte, Grade IV Goutallier, and Grade II Hamada), without glenohumeral arthritis, intact biceps tenosynovitis, and subscapularis. The preoperative Constant score was 40 points. The patient underwent partial arthroscopic repair of the supraspinatus and infraspinatus tendons, along with a suprapectoral biceps tenodesis and subacromial balloon placement. Postoperative rehabilitation led to improved range of motion, reduced pain, and increased strength in the right shoulder. The postoperative Constant score reached 80 points at the twelve-week mark. The subacromial balloon proves to be a promising treatment alternative for irreparable rotator cuff injuries, providing optimal short-term results in terms of pain relief and functionality.

Abstract Objective To investigate the effectiveness of human recombinant epidermal growth factor in the healing of rotator cuff tear in the rabbit shoulder. Methods Rotator cuff tears (RCTs) were experimentally created on both shoulders of 20 New Zealand rabbits. The rabbits were divided into the following groups: RCT (sham group; n = 5), RCT + EGF (EGF group; n = 5), RCT + transosseous repair (repair group; n = 5), and RCT + EGF + transosseous repair (combined repair + EGF group; n = 5). All rabbits were then observed for 3 weeks, and biopsies were taken from the right shoulders in the third week. After three more weeks of observation, all rabbits were sacrificed, and a biopsy removed from their left shoulders. All biopsy material was stained with haematoxylin & eosin (H&E) and vascularity, cellularity, the proportion of fibers and the number of fibrocartilage cells were evaluated under light microscope. Results The highest collagen amount and the most regular collagen sequence was detected in the combined repair + EGF group. The repair group and the EGF group showed higher fibroblastic activity and capillary formation when compared with the sham group, but the highest fibroblastic activity and capillary formation with highest vascularity was detected in the combined repair + EGF group (p < 0.001). EGF seems to improve wound healing in the repair of RCT. The EGF application alone, even without repair surgery, seems to be beneficial to RCT healing. Conclusion In addition to rotator cuff tear repair, application of human recombinant epidermal growth factor has an effect on rotator cuff healing in rabbit shoulders.
Resumo Objetivo Investigar a eficácia do fator de crescimento epidérmico (EGF) recombinante humano na cicatrização da lesão do manguito rotador no ombro de coelhos. Métodos As rupturas do manguito rotador (RMRs) foram criadas experimentalmente em ambos os ombros de 20 coelhos Nova Zelândia. Os coelhos foram divididos nos seguintes grupos: RMR (grupo controle; n = 5), RMR + EGF (grupo EGF; n = 5), RMR + reparo transósseo (grupo reparo; n = 5) e RMR + EGF + reparo transósseo (grupo reparo combinado+ EGF; n = 5). Todos os coelhos foram observados por 3 semanas, e amostras de biópsias foram coletadas do ombro direito na 3ª semana. Após mais 3 semanas de observação, todos os coelhos foram submetidos à eutanásia, e uma amostra de biópsia foi coletada dos ombros esquerdos. Todo o material de biópsia foi corado com hematoxilina e eosina (H&E) para avaliação de vascularidade, celularidade, proporção de fibras e número de células fibrocartilaginosas à microscopia óptica. Resultados O grupo reparo combinado + EGF apresentou a maior quantidade e a sequência mais regular de colágeno. O grupo reparo e o grupo EGF apresentaram maior atividade fibroblástica e formação capilar em comparação ao grupo controle, mas a maior atividade fibroblástica e a formação capilar com maior vascularidade foram detectadas no grupo reparo combinado + EGF (p < 0,001). O EGF parece melhorar a cicatrização da ferida no reparo da RMR. A aplicação isolada de EGF, mesmo sem cirurgia reparadora, parece melhorar a cicatrização da RMR. Conclusão Além do reparo da RMR, a aplicação de EGF recombinante humano auxilia a cicatrização do manguito rotador dos ombros de coelhos.

Abstract Objective Shoulder pain is a common presentation in the primary care setting, and shoulder pain after vaccination has a growing body of literature. The present study sought to understand how a standardized treatment protocol would aid patients experiencing shoulder injury related to vaccine administration (SIRVA). Methods Patients experiencing SIRVA were retrospectively recruited between February 2017 and February 2021. All patients were treated with physical therapy and offered a cortisone injection. Post-treatment range of motion (i.e., forward elevation, external rotation, internal rotation) and patients' reported outcomes were collected with the visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), simple shoulder test (SST), and single assessment numeric evaluation (SANE) scores. Results A total of 9 patients were retrospectively examined. Among them, 6 patients presented within one month of a recent vaccination event, while 3 patients presented 67, 87, and 120 days after vaccination. Furthermore, 8 of the patients completed physical therapy, and 6 of them underwent a cortisone injection. The follow-up time averaged 8 months. At final follow-up, the mean external rotation was 61º (standard deviation, SD±3º) and the mean forward elevation was 179º (SD±45º). Internal rotation ranged between L3 and T10. The VAS pain scores were 3.5/10.0 (SD±2.4), the mean ASES score was 63.5/100.0 (SD±26.3), and the SST scores were 8.5/12.0 (SD±3.9). Finally, the SANE scores were 75.7/100.0 (SD±24.7) and 95.7/100.0 (SD±6.1) in the injured and contralateral shoulders respectively. Conclusion Shoulder pain after a vaccination treated with physical therapy and cortisone injection ultimately resulted in favorable shoulder range of motion and functional score outcomes. Level of Evidence IV
Resumo Objetivo A dor no ombro é um quadro comum na atenção primária e há cada vez mais relatos acerca de sua ocorrência após a vacinação. Este estudo buscou entender como um protocolo de tratamento padronizado ajudaria pacientes com lesão no ombro relacionada à administração de vacina (SIRVA). Métodos Os pacientes com SIRVA foram recrutados de forma retrospectiva entre fevereiro de 2017 e fevereiro de 2021. Todos os pacientes foram submetidos à fisioterapia e receberam uma prescrição de cortisona injetável. A amplitude de movimento pós-tratamento (ou seja, elevação anterior, rotação externa, rotação interna) e os desfechos relatados pelo paciente foram analisados a partir das pontuações da escala visual análoga (EVA), da American Shoulder and Elbow Surgeons (ASES), do teste simples do ombro (SST) e da avaliação numérica única (SANE). Resultados No total, 9 pacientes foram examinados de maneira retrospectiva. Entre eles, 6 pacientes foram atendidos no primeiro mês após a vacinação e os outros três, depois de 67, 87 e 120 dias. Ademais, 8 dos pacientes fizeram todo o tratamento fisioterápico e 6 receberam uma injeção de cortisona. O período médio de acompanhamento foi de 8 meses. À última consulta, a rotação externa média foi de 61° (desvio padrão, DP±3°)ea elevação anterior média foi de 179° (DP ± 45°). A rotação interna variou entre L3 e T10. As pontuações de dor à EVA foram de 3,5/10,0 (DP ± 2,4) e o escore médio ASES foi de 63,5/100,0 (DP ± 26,3); as pontuações de SST foram 8,5/12,0 (DP ± 3,9). Por fim, os escores de SANE foram de 75,7/100,0 (DP ± 24,7) e 95,7/100,0 (DP ± 6,1) nos ombros lesionados e contralaterais, respectivamente. Conclusão A dor no ombro após a vacinação tratada com fisioterapia e injeção de cortisona melhorou a amplitude de movimento e os escores funcionais. Nível de Evidência IV

The rotator cuff is an important structure to maintain movement and dynamic stability of the shoulder joint. Rotator cuff injury changes its unique biomechanical effects, resulting in shoulder pain and mobility disorders. Although great progress has been made in suture technology and fixation method, the rate of postoperative retear is still very high. Understanding the biomechanical mechanism of normal rotator cuff and restoring the special biomechanical effect of rotator cuff after injury are the key to prevent postoperative retear. This article reviewed biomechanical researches on rotator cuff repair in recent years, in order to provide some theoretical guidance for clinical operation.

Objective:To compare the clinical efficacy between reservation and sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear.Methods:A retrospective study was conducted to analyze the clinical data of 32 patients with rotator cuff tear plus remnants in the footprint area (2 cm < tear size <5 cm) who had been admitted to Department of Sports Medicine, The People's Hospital of Northern Jiangsu from May 2020 to July 2021. The patients were divided into 2 groups according to reservation or sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear. In the remnant-reservation group (16 cases): 5 males and 11 females with an age of (61.8±9.9) years, 9 left and 7 right shoulders affected, and (3.7±1.1) cm in size of rotator cuff tear; in the remnant-sacrifice group (16 cases): 4 males and 12 females with an age of (61.3±8.8) years, 8 left and 8 right shoulders affected, and (3.9±0.9) cm in size of rotator cuff tear. The 2 groups were compared in terms of visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder function score (Constant score), and range of motion of the affected shoulder before surgery, 3 months after surgery and at the last follow-up. The ratio of bilateral abductor muscle strengths (affected side/healthy side) was analyzed and compared between the 2 groups, and the healing of the rotator cuff was evaluated by MRI at the last follow-up.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). The 32 patients were followed up for (14.3±3.5) months after surgery. At 3 months after surgery, the VAS score in the remnant-reservation group [1.0 (0.0,1.0) point] was significantly lower than that in the remnant-sacrifice group [1.0 (1.0,1.0) point] ( P<0.05), but there was no significant difference between the 2 groups in ASES score, Constant score or range of motion of the affected shoulder ( P>0.05). At the last follow-up, the ASES score, forward flexion, abduction and ratio of bilateral abductor muscle strengths (affected side/healthy side) in the remnant-reservation group [(96.1±4.8) points, 170.0 (170.0,170.0)°, 160.0 (160.0,170.0)°, and 85.5%±13.8%]were significantly better than those in the remnant-sacrifice group [(91.4±5.9) points, 160.0 (160.0,170.0)°, 150.0 (140.0,155.0)°, and 72.6%±16.9%] ( P < 0.05), but there were no statistically significant differences between the 2 groups in VAS score, Constant score, neutral external rotation angle, or body-side internal rotation ( P>0.05). The Sugaya grading for MRI rotator cuff healing was significantly different between the 2 groups at the last follow-up ( P<0.05). Conclusion:In arthroscopic repair of rotator cuff tear, reservation of remnants in the footprint area can significantly relieve postoperative shoulder pain, and has obvious advantages in restoration of shoulder forward flexion, abduction and abductor muscle strength, leading to better healing of the rotator cuff and the large nodule than the remnant-sacrifice technique.

Objective:To investigate the early clinical effect of fascia lata autograft bridging combined with the long head of biceps tendon transposition for treatment of irreparable massive rotator cuff tear.Methods:All of 31 cases of massive irreparable rotator cuff tear treated in our hospital from March 2016 to March 2020 were analyzed retrospectively. Among them, 17 cases (10 males, 7 females) were repaired with fascia lata autograft bridging under arthroscopy (patch group), the average age was 61.47±6.63 (ranging from 51 to 72) and 14 cases (4 males, 10 females) were repaired with fascia lata autograft bridging combined with the long head of biceps tendon transposition (combined group), the average age was 62.57±6.11 (ranging from 53 to 71). The operation time, intraoperative blood loss, postoperative complications, visual analogue scale (VAS) of pain before operation, at 1 week and 12 months after operation, Constant-Murley score of shoulder joint and American Association of shoulder and elbow Surgeons (ASES) score before operation, at 6 months and 12 months after operation were compared between the two groups. The outcome of rotator cuff healing was evaluated by MRI 1 year after operation.Results:All patients were followed up for 12-27 months (mean 18.33 ±6.8 months). There was no perioperative complication, and there was no significant difference in operation time between the two groups ( P>0.05) . The VAS score in the patch group was significantly higher than the combined group 1 week after operation ( t=2.09, P=0.048) , and there was no significant difference in VAS score 12 months after operation between the two groups. Constant-Murley score and ASES score in the combined group were significantly higher than the patch group at 6 months after operation ( t=5.23, P<0.001; t=4.45, P<0.001) , and there was no significant difference in Constant score and ASES score between the two groups at 12 months after operation. Constant score and ASES score in the two groups were significantly higher than those before operation. One year after operation, the MRI of the affected shoulder showed that the incidence of autograft patch thinning (Sugaya grade III) was 52.94%, the autograft patch structure failure rate (Sugaya grade IV and V) was 17.65% in the patch group, the autograft patch thinning rate (Sugaya grade III) was 35.71%, and the structural failure rate (Sugaya grade IV and V) was 7.14% in the combined group. The difference was statistically significant (χ 2=7.12, P=0.028) . Conclusion:Fascia lata autograft patch bridging combined with long head of biceps tendon transposition technique for treatment of irreparable massive rotator cuff tear has less pain 1 week after operation and better recovery of shoulder function half a year after operation. MRI showed better patch healing 1 year after operation.

Objective:To compare the clinical and imaging outcomes of fascia lata autograft bridging repair reinforecd with an artificial ligament as the internal brace with the autograft bridging repair for the treatment of irreparable massive rotator cuff tears (IMRCTs).Methods:The data of 26 patients with IMRCT who underwent fascia lata autograft bridging repair augmented with artificial ligament as the internal brace (internal brace group) and of 24 patients with IMRCT who underwent bridging autograft repair alone (control group) were retrospectively evaluated preoperatively and at 2-year follow-up. Clinical outcomes were assessed using shoulder activity, the American Shoulder and Elbow Surgeons (ASES) Score, University of California Los Angeles (UCLA) Score, and visual analogue scale (VAS) for pain. Imaging outcomes were evaluated using acromiohumeral distance (AHD), Goutallier grade, and status of fascia lata grafts according to radiographs or magnetic resonance imaging results.Results:All 50 cases were followed up for 34.2±7.2 months (range 24-45 months). Compared to the control group, the internal brace group showed better ASES score (93.5±5.3 vs. 89.5±5.7, P<0.05), UCLA score (31.7±3.8 vs. 28.5±5.6, P<0.05), improvement in UCLA score (19.6±4.2 vs. 15.9±5.7, P<0.05), active elevation (167.3°±8.4° vs. 159.4°±13.6°, P<0.05), abduction strength (8.9±1.2 vs. 8.2±1.2, P<0.05), improvement in abduction strength (4.1±1.2 vs. 3.3± 1.0, P<0.05), AHD (7.0±1.4 mm vs. 5.9±1.0 mm, P<0.05), improvement in AHD (3.3±1.5 mm vs. 2.0±0.6 mm, P<0.05), and healing rate of fascia lata autografts (92% vs. 54%, P<0.05) at 2-year follow-up. Conclusion:Fascia lata autograft bridging repair reinforced with an artificial ligament as the internal brace improves healing rate of bridging graft and postoperatively short-term clinical outcomes of patients with IMRCT.

Regeneration of rotator cuff tendon-bone interface is crucial in rotator cuff repair. The tendon-bone interface consists of four continuous and gradual regions: the tendon region, the unmineralized fibrocartilage region, the mineralized fibrocartilage region, and the bone region. The development and regeneration of various regions in the tendon-bone interface is regulated by growth factors, inorganic ions, mechanical stimulation, and hypoxic environment. Inspired by factors affecting the development and regeneration of the tendon-bone interface, many researchers have designed gradient scaffold systems that promote regionalized regeneration of the tendon-bone interface. The gradient distribution of these scaffolds includes inorganic ion gradients and growth factor gradients. According to different gradients of the scaffold system, osteogenesis, chondrogenesis and tendon differentiation of cells at the tendon-bone interface are promoted, and the healing of the tendon-bone is synchronously completed to realize the repair and regeneration of the rotator cuff tendon-bone interface. Current studies indicated that gradient multiphase scaffolds had high academic research value and guided significance for future clinical applications in the reconstruction of the tendon-bone interface. In this paper, the factors affecting the development and regeneration of the tendon-bone interface are reviewed, and the effects of these factors on osteogenesis, chondrogenesis and tendon formation of various regions in promoting rotator cuff tendon-bone interface repair are summarized. The properties and effects of reported gradient multiphase scaffolds for rotator cuff injury are discussed, including gradient scaffolds containing inorganic ions and growth factors. Finally, the problems and future development opportunities of gradient multiphase support in rotator cuff repair are summarized.

Objective:To investigate the clinical characteristics of hip rotator-cuff tear, arthroscopic repair techniques, and short-term clinical efficacy.Methods:A retrospective analysis was performed on the patient cohort from our department who underwent arthroscopic repair for hip rotator-cuff tears from September 2019 to May 2021, with a minimum follow-up duration of two years. The sample included 17 subjects, composed of 6 males and 11 females, with a median age of 56 years (interquartile range 49.5-62.5). Notably, 9 patients (53%) reported nocturnal pain, and 10 patients (59%) exhibited a positive hip flexion resistance test. Patients' demographic details, clinical manifestations, radiographic findings, and intraoperative observations were analyzed. Pain amelioration was gauged by the visual analogue scale (VAS) at preoperative, 1 month, 3 months, and 6 months postoperative intervals. Enhancement in hip functionality was assessed by comparing the modified Harris hip score (mHHS), and the International hip outcome tool-12 (iHOT-12) at preoperative, 6 months, 12 months, and 24 months postoperative junctures.Results:All interventions were successfully completed, with an average surgical duration of 91.2±18.3 minutes. The follow-up period averaged 29 months. Every patient presented with a hip rotator-cuff tear, which was corrected using anchor suturing. 10 patients also had concomitant labrum injuries, with 5 cases undergoing labrum repair. The VAS score decreased from preoperative 5.24±1.15 to postoperative 2.29±0.69 at 1 month, 1.77±0.56 at 3 months, and 1.59±0.62 at 6 months ( F=79.31, P<0.001); The mHSS score increased from preoperative 49.59±6.11 to postoperative 81.00±3.89 at 6 months, 81.71±3.41 at 12 months, and 81.94±3.29 at 24 months ( F=232.00, P<0.001); The iHOT-12 score increased from preoperative 42.65±6.04 to postoperative 6 months 66.53±3.43, 12 months 68.12±3.48, and 24 months 69.06±3.53 ( F=150.00, P<0.001). Conclusion:Diagnosing hip rotator-cuff tears necessitates specific physical examinations complemented by high-definition magnetic resonance imaging. Arthroscopic surgery represents a potent treatment modality for hip rotator-cuff injuries, demonstrating substantial short-term clinical efficacy.

Objective:To investigate the correlation between anatomical features of shoulder joint and postoperative stiffness after rotator cuff repair.Methods:212 patients diagnosed with rotator cuff injury undergoing rotator cuff repair in Civil Aviation General Hospital from March 2016 to December 2021 were enrolled. There were 97 male and 115 female with an average age of 58.87±9.69 years old (range, 41-72). The patients were divided into stiffness group (SG) and non-stiffness group (NG) according to the range of shoulder joint motion at 3-month after operation. Preoperative and postoperative joint anatomical features including critical shoulder angle (CSA), acromial index (AI), lateral acromion angle (LAA) were measured and calculated through CT scan and 3-dimension reconstruction. Age, sex, course of disease, body mass index, tendon fatty infiltration degree, type of rotator cuff injury according to DeOrio & Cofield classification, suture method, and preoperative and 3-month postoperative range of shoulder motion (flexion, abduction, and external rotation), preoperative stiffness condition were collected. All factors between two groups were compared, and binomial logistic regression analysis was performed to find out the risk factors of postoperative joint stiffness. Receiver operating characteristic (ROC) curves were plotted to evaluate the predictive efficacy of postoperative CSA, AI, and LAA for postoperative joint stiffness.Results:43 patients were enrolled in SG and 169 patients were enrolled in NG. Age, sex, course of disease, body mass index, tendon fatty infiltration degree, type of rotator cuff injury according to DeOrio & Cofield classification, suture method, and preoperative range of shoulder motion (flexion, abduction, and external rotation) between two groups were insignificantly different ( P>0.05). The ratio of patients with preoperative stiffness in SG is higher than that in NG (χ 2=40.38, P<0.001). Postoperative CSA and AI of SG were greater than those of NG ( t=5.44, P<0.001; t=4.89, P<0.001), and postoperative LAA of SG was smaller than that of NG group ( t=-5.86, P<0.001). Preoperative stiffness, large postoperative AI and small postoperative LAA were all risk factors of joint stiffness after rotator cuff suture [ OR=9.32, 95% CI(3.44, 25.27), P<0.001; OR=2.39, 95% CI(1.58, 3.62), P<0.001; OR=0.64, 95% CI(0.46, 0.91), P=0.012]. Postoperative CSA, AI and LAA had a certain predictive effect on postoperative joint stiffness (AUC>0.70). LAA was the most sensitive factor and CSA was the most specific factor. The optimal cutoff values of CSA, AI and LAA were 34.4°, 0.70 and 74.5° respectively, and the AUC for predicting postoperative joint stiffness were 0.76 [ OR=0.98, 95% CI(0.69, 0.84), P<0.001]、0.78[ OR=2.39, 95% CI(0.70, 0.84), P<0.001]、0.76[ OR=0.64, 95% CI(0.68, 0.83), P<0.001]. Conclusion:Postoperative CSA, AI and LAA had predictive efficacy on joint stiffness after rotator cuff repair. The greater postoperative CSA and AI or smaller postoperative LAA indicates increased risk of postoperative joint stiffness. LAA was the most sensitive factor and CSA was the most specific factor.

Abstract Objective The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft. Methods A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI). Results Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 (p= 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences (p= 0.001; p= 0.005; and p= 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°, p= 0.003; 30 to 60°, p= 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing. Conclusions Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up. Level of Evidence IV; Therapeutic Study; Case Series.
Resumo Objetivo O objetivo do presente estudo foi avaliar a eficácia e a segurança da reconstrução capsular superior (RCS) com a utilização do aloenxerto de fáscia lata. Métodos Uma série de casos prospectivos de 15 pacientes com ruptura irreparável do supraespinhal foi submetida a RCS com aloenxerto de fáscia lata, sendo adotada como desfecho primário a escala American Shoulder and Elbow Surgeons (ASES, na sigla em inglês) aos 12 meses do pós-operatório. Como desfechos secundários, foram adotadas as escalas da University of California Los Angeles (UCLA, na sigla em inglês), Constant-Murley, e Single Assessment Numeric Evaluation (SANE, na sigla em inglês), além da amplitude de movimento. Os parâmetros radiológicos também foram avaliados por radiografias simples e ressonância magnética (RM). Resultados Quinze pacientes completaram 12 meses de acompanhamento pós-operatório. O escore ASES aumentou de 34,0 para 73,0 (p= 0,005). As escalas UCLA, Constant-Murley e SANE também apresentaram diferenças estatisticamente significativas (p= 0,001; p= 0,005; e p= 0,046).

Abstract Objective The primary aim of the present study is to evaluate the functional results of a modification to the latissimus dorsi (LD) transfer around the shoulder for irreparable posterosuperior rotator cuff tears. The secondary aim is to evaluate variables that might influence the outcomes. Surgical Technique Through a single deltopectoral approach, the LD tendon is detached, reinforced, and elongated with a tendinous allograft, transferred around the humerus, and fixed superolaterally to the greater tuberosity and anteriorly to the subscapularis. Methods Retrospective functional evaluation of 16 cases. The average follow-up was 21 months (12-47). The postoperative results (at last follow-up) were compared with the preoperative ones, as well as to other pre, intra, and postoperative variables. Results All (but one) patients were satisfied. Average University of California, Los Angeles (UCLA) score increased from 11.6 (8-16) to 27.3 (17-30) (p< 0.001). Improvements of shoulder pain, function, and strength achieved statistical significance (p< 0.001). Nonetheless, normal strength was never restored. Average active range of motion improved as follows: forward elevation, from 106° (60-140°) to 145° (130-160°) (p< 0.001); external rotation from 30° (0° to 60°) to 54° (40-70°) (p< 0.001); and internal rotation from L1 (gluteus to T7) to T10 (T12-T3) (p< 0.05). No complication has occurred. Preoperative pseudoparesis was reverted in all the six cases in which it was present. None of the variables analyzed influenced the outcomes, including pseudoparesis. Conclusions At early follow-up, this technique is safe and effective at recovering from pseudoparesis and at improving shoulder pain, function, and strength.
Resumo Objetivo O objetivo primário do presente trabalho é avaliar os resultados funcionais de uma modificação na transferência do grande dorsal no ombro para o tratamento de lesões póstero-superiores irreparáveis do manguito rotador. O objetivo secundário é avaliar as variáveis que podem influenciar os resultados. Técnica cirúrgica Por meio de uma única abordagem deltopeitoral, o tendão do músculo grande dorsal é desinserido reforçado e alongado com um enxerto tendíneo homólogo, transferido para o úmero e fixado em posição superolateral ao tubérculo maior e anterior ao músculo subescapular. Métodos Avaliação funcional retrospectiva de 16 casos. O período médio de acompanhamento foi de 21 meses (12-47 meses). Os resultados pós-operatórios (no último acompanhamento) foram comparados aos pré-operatórios, bem como a outras variáveis pré, intra e pós-operatórias. Resultados Todos os pacientes ficaram satisfeitos (exceto um). A pontuação média da University of California, Los Angeles (UCLA) aumentou de 11,6 (8-16) para 27,3 (17-30) (p< 0,001). A dor, a função e a força do ombro apresentaram melhora estatisticamente significativa (p< 0,001). A força, porém, não voltou ao valor normal. A amplitude de movimento ativa média apresentou as seguintes melhoras: elevação frontal, de 106° (60-140°) para 145° (130-160°) (p< 0,001); rotação externa, de 30° (0-60°) para 54° (40-70°) (p< 0,001); e rotação interna, de L1 (glúteo a T7) para T10 (T12-T3) (p< 0,05). Nenhuma complicação foi observada. A pseudoparesia pré-operatória foi revertida em todos os seis casos em que foi observada. Nenhuma das variáveis analisadas influenciou os desfechos, nem mesmo a pseudoparesia. Conclusões A curto prazo essa técnica é segura e eficaz na recuperação da pseudoparesia e na melhora da dor, da função e da força do ombro.

Abstract Much is discussed about the limits of the treatment of anterior shoulder instability by arthroscopy. The advance in understanding the biomechanical repercussions of bipolar lesions on shoulder stability, as well as in the identification of factors related to the higher risk of recurrence have helped us to define, more accurately, the limits of arthroscopic repair. We emphasize the importance of differentiation between glenoid bone loss due to erosion (GBLE) and glenoid edge fractures, because the prognosis of treatment differs between these forms of glenoid bone failure. In this context, we understand that there are three types of bone failure: a) bone Bankart (fracture); b) combined; and c) glenoid bone loss due to anterior erosion (GBLE), and we will address the suggested treatment options in each situation. Until recently, the choice of surgical method was basically made by the degree of bone involvement. With the evolution of knowledge, the biomechanics of bipolar lesions and the concept of glenoid track, the cutoff point of critical injury, has been altered with a downward trend. In addition to bone failures or losses, other variables were added and made the decision more complex, but a little more objective. The present update article aims to make a brief review of the anatomy with the main lesions found in instability; to address important details in arthroscopic surgical technique, especially in complex cases, and to bring current evidence on the issues of greatest divergence, seeking to guide the surgeon in decision making.
Resumo Muito se discute sobre os limites do tratamento da instabilidade anterior do ombro por artroscopia. O avanço no entendimento das repercussões biomecânicas das lesões bipolares sobre a estabilidade do ombro, bem como na identificação de fatores relacionados ao maior risco de recidiva têm nos ajudado a definir, de forma mais apurada, os limites do reparo por via artroscópica. Ressaltamos a importância de diferenciação entre perda óssea por erosão da glenoide (POAG) e fraturas da borda da glenoide, pois o prognóstico do tratamento diverge entre essas formas de falha óssea da glenoide. Neste contexto, entendemos que há três tipos de falha óssea: a) Bankart ósseo (fratura); b) combinada; e c) POAG, e abordaremos as opções de tratamento sugerido em cada situação. Até há pouco tempo, a escolha do método cirúrgico era norteada basicamente pelo grau de acometimento ósseo. Com a evolução do conhecimento, da biomecânica das lesões bipolares e do conceito do glenoid track (trilho da glenoide), o ponto de corte da lesão crítica, vem sendo alterado com tendência de queda. Além das falhas ou perdas ósseas, outras variáveis foram adicionadas e tornaram a decisão mais complexa, porém um pouco mais objetiva. O presente artigo de atualização tem como objetivo fazer uma breve revisão da anatomia com as principais lesões encontradas na instabilidade; abordar detalhes importantes na técnica cirúrgica artroscópica, em especial nos casos complexos, e trazer as evidências atuais sobre os assuntos de maior divergência, buscando guiar o cirurgião na tomada de decisão.

Objective:To evaluate the relationship of rotator cuff muscle function with shoulder abduction function after posterior superior rotator cuff tear via dynamic biomechanical study.Methods:By using the customized dynamic shoulder biomechanical testing system, seven freshly frozen cadaveric shoulders were used to stimulate shoulder abduction at 90° under four statuses: (1) intact rotator cuff with activation (normal rotator cuff group); (2) posterior superior rotator cuff tear with activation (posterior superior rotator cuff tear with activation group); (3) posterior superior rotator cuff tear with posterior superior rotator cuff deactivation (posterior superior rotator cuff tear with deactivation group); (4) none rotator cuff tissue above the geometric rotation center of the humeral head with deactivation (global tear group). The peak and stable value of middle deltoid force were used to evaluate biomechanical status in different rotator cuff tear conditions during shoulder abduction procedure. The peak subacromial pressure, average subacromial pressure, subacromial contact area, and subacromial force were used to evaluate subacromial pressed conditions under different rotator cuff tear conditions. The peak and stable ratio of glenohumeral contact force/middle deltoid force were used to evaluate shoulder stability under different rotator cuff tear conditions.Results:During dynamic abduction at 90°, the peak and stable value of middle deltoid force were (42.1±8.7)N and (29.9±7.4)N in normal rotator cuff group, (45.7±10.3)N and (30.5±7.2)N in posterior superior rotator cuff tear with activation group, and (48.4±13.4)N and (29.9±4.8)N in posterior superior rotator cuff tear with deactivation group (all P>0.05). But the peak and stable value of middle deltoid force were (69.7±9.7)N and (53.7±8.9)N in global tear group, significantly increased compared with other three groups (all P<0.05). The elevated middle deltoid force increased the subacromial contact pressure between glenohumeral head and acromion. The peak subacromial pressure, average subacromial pressure, subacromial contact area, and subacromial force were (0.40±0.05)MPa, (0.22±0.03)MPa, (7.71±5.09)mm 2, and (1.66±1.06)N respectively in normal rotator cuff group, (0.41±0.05)MPa, (0.26±0.07)MPa, (12.71±11.35)mm 2, and (2.93±2.46)N respectively in posterior superior rotator cuff tear with activation group, and (0.50±0.12)MPa, (0.26±0.07)MPa, (17.29±9.11)mm 2, and (4.09±1.46)N respectively in posterior superior rotator cuff tear with deactivation group (all P>0.05). However, the peak subacromial pressure, average subacromial pressure, subacromial contact area, and subacromial force were (3.64±1.70)MPa, (0.98±0.49)MPa, (47.63±11.91)mm 2, and (45.48±23.86)N respectively in global tear group, significantly higher than those in other three groups (all P<0.05). The peak and stable ratio of glenohumeral contact force/middle deltoid force were 2.24±0.30 and 2.46±0.13 in normal rotator cuff group, 2.21±0.19 and 2.52±0.08 in posterior superior rotator cuff tear with activation group, and 2.03±0.14 and 2.42±0.16 in posterior superior rotator cuff tear with deactivation group (all P>0.05). However, the peak and stable ratio of glenohumeral contact force/middle deltoid force were 1.40±0.14 and 1.52±0.41 in global tear group, significantly higher than those in other three groups (all P<0.05). No significant differences of the above parameters were observed in posterior superior rotator cuff tear with activation group, posterior superior rotator cuff tear with deactivation group and global tear group (all P>0.05). Conclusions:After posterior superior rotator cuff tear, rotator cuff muscle function does not affect the whole abduction function of shoulder. When the size of rotator cuff tear involves the whole superior humeral head rotation center, the normal abduction function of shoulder will be significantly impaired.

Objective:To investigate the effects of Manchester Pain Management Model (MPMM) on postoperative pain and joint function for patients undergoing rotator cuff repair surgery.Methods:A total of 66 patients undergoing rotator cuff repair surgery from February 2017 to October 2020 in the First People′s Hospital of Hefei were divided into experimental group and control group by random digits table method, with 33 cases in each group. The control group received routine nursing; based on the routine care, the experimental group implemented MPMM-based intervention. The degree of pain and shoulder function of the two groups were assessed by Visual Analogue Scale (VAS) and Constant-Murley Scale (CMS).Results:During the study period, 1 case in the experimental group was lost, 32 cases in the final experimental group and 33 cases in the control group. There was no significant difference in the score of VAS and CMS before surgery between the two groups ( P>0.05). At 1 day, 3 days, 3 weeks and 6 weeks after surgery, VAS scores in the experimental group were 5.47 ± 1.72, 4.63 ± 1.16, 3.25 ± 0.78, 1.81 ± 0.52, lower than those scores in the control group 6.42 ± 1.03, 5.45 ± 1.54, 4.30 ± 0.64, 2.39 ± 0.47, the differences were statistically significant ( t values were 2.36-3.11, all P<0.05). At 3, 6, 12 weeks after surgery, CMS scores in the experimental group were 57.09 ± 4.32, 67.75 ± 4.60, 81.94 ± 4.18, higher than those scores in the control group 52.27 ± 5.39, 64.24 ± 3.76, 78.91 ± 4.36, the differences were statistically significant ( t=3.97, 3.37, 2.89, all P<0.01). Conclusions:MPMM can effectively alleviate the postoperative pain and promote the recovery of joint function in patients undergoing rotator cuff repair surgery.

Objective:To compare the clinical efficacy of platelet-rich plasma (PRP) injection and conventional treatment for partial rotator cuff tear and analyze the possible mechanism.Methods:A prospective randomize control study was performed for clinical data of 100 patients with partial rotator cuff tear admitted to Beijing Tongren Hospital affiliated to Capital Medical University between January 2019 and December 2020. The patients were assigned to observation group ( n=50) and control group ( n=50) according to the random number table. Both groups were given conventional non-operative treatment, together with PRP injection in observation group and steroid injection in control group. The visual analogue score (VAS), Constant-Murley Score (CMS) and serum levels of inflammatory cytokines [interleukin-6 (IL-6), IL-1β, tumor necrosis factor-α (TNF-α)] were measured before and at 3, 6 months after treatment. The MRI images were also evaluated in observation group before treatment and at 6 months after treatment. Results:There were 55 males and 45 females with the age range of 40-75 years [(55.9±9.1)years]. All patients were followed up for 6.0-8.2 months [(6.2±2.9)months]. There were no significant differences between the two groups in VAS, CMS, IL-6, IL-1β and TNF-α before treatment (all P>0.05). The VAS was (3.5±0.9)points and (1.4±0.4)points] in observation group at 3, 6 months after treatment, significant lower than (4.1±0.9)points and (1.8±0.5)points in control group (all P<0.01). The CMS was (59.5±9.4)points and (86.5±7.9)points in observation group at 3, 6 months after treatment, significant higher than (53.5±8.6)points and (78.5±8.4)points in control group (all P<0.01). The serum levels of IL-6, IL-1β and TNF-α were (0.69±0.21)μg/L, (2.06±0.55)μg/L and (2.12±0.49)μg/L in observation group at 3 months after treatment, significant lower than (0.92±0.26)μg/L, (2.67±0.48)μg/L and (2.87±0.51)μg/L in control group (all P<0.01). The serum levels of IL-6, IL-1β and TNF-α in observation group [(0.37±0.11)μg/L, (1.14±0.23)μg/L, (1.27±0.25)μg/L] were also significantly lower than those in control group [(0.45±0.09)μg/L, (1.36±0.27)μg/L, (1.88±0.26)μg/L] at 6 months after treatment (all P<0.01). In both groups, the VAS, CMS and inflammatory cytokines (IL-6, IL-1β, TNF-α) showed significant improvement at 3, 6 months after treatment when compared to the pre-treatment levels (all P<0.05). Simutaneously, each group showed significant differences in each indicator at 3, 6 months after treatment ( P<0.05). In observation group, MRI showed that the high signal on the superior surface of the supraspinatus disappeared whereas the high signal in the tendon decreased at 6 months after treatment. Conclusion:For patients with partial rotator cuff tear, PRP injection can relive shoulder pain and improve shoulder function, which may be associated with the down-regulation of inflammatory responses.

Objective:To evaluate the short-term effects of arthroscopic biceps rerouting along with rotator cuff repair in treating large to massive rotator cuff tears.Methods:Retrospective evaluation of patients with large to massive rotator cuff tears who were treated with arthroscopic biceps rerouting along with rotator cuff repair was conducted from May 2017 to September 2020. There were 48 patients with average age 58.7±18.4 years (range from 45-72 years), of which 19 cases were males and 29 cases were females. The following outcomes, range of motion, functional outcomes, pain and radiological outcomes, were assessed perioperatively. Pain symptom was assessed according to visual analogue scale (VAS). The functional outcomes were assessed according to American Shoulder and Elbow Surgeons (ASES) score and Constant-Murley score. MRI was used to evaluate radiological outcomes preoperatively and at 3, 6, 12 months postoperatively.Results:All forty-eight patients were followed-up. The mean duration of follow-up was 24.2±33.5 months (range from 13-53 months) after surgery. The average VAS of the patients decreased from 6.4±1.8 before surgery to 4.6±2.2 at 6 months after surgery, to 1.9±2.1 at 12 month after surgery, and to 1.7±2.0 at the last follow-up with significant difference ( F=4.47, P<0.001) . ASES score decreased from 56.4±20.9 before surgery to 48.3±29.1 at 6 months after surgery, and increased to 77.2±18.2 at one year after surgery, and to 82.3±13.8 at the last follow-up with statistically significant difference ( F=36.34, P<0.001). The Constant-Murley decreased from 52.7±17.5 before surgery to 49.4±27.5 at 6 months after surgery, and increased to 80.1±20.1 at one year after surgery and to 87.4±11.9 at the last follow-up, respectively. The difference between the preoperative and the last follow-up was statistically significant ( F=52.68, P<0.001). The forward flexion increased from 102°±24° preoperatively to 121°±33° at 6 months, to 140°±17° at 12 months, and to 148°±15° at the last follow-up ( F=34.24, P<0.001). External rotation decreased from 57°±32° before surgery to 45°±37° at 6 months, and increased to 70°±31° at 12 months after surgery and to 75°±30° at the last follow-up with significant difference ( F=19.68, P=0.042). Internal rotation decreased from 8±3 before surgery to 7±4 at 6 months, and increased to 9±3 at 12 months after surgery and to 10±2 at the last follow-up with significant difference ( F=11.86, P=0.015). Six patients (12.5%) underwent retear of the repaired rotator cuff on the postoperative MRI, of which 4 cases were confirmed at 3 months after surgery and 2 cases at 6 months after surgery. Conclusion:Arthroscopic biceps rerouting along with rotator cuff repair for the treatment of large to massive rotator cuff injuries could significantly relieve pain symptoms and improve shoulder joint function without the help of scaffold. The present technique has lower retear rate.

OBJECTIVE@#To explore the MRI findings of os acromiale and to analyze the relationship between os acromiale and the supraspinatus and infraspinatus injury.@*METHODS@#From January 2010 to August 2020, 21 patients with os acromiale (os arcomiale group) were compared with 21 subjects with no evidence of os acromiale (no os arcomiale group). There were 14 males and 7 females in the os arcomiate group, aged from 29 to 77 years old, mean aged (55.5±11.5) years old. While in the control group, there were 10 males and 11 females in no os arcomiale group, aged from 31 to 70 years old, mean aged (51.1±10.0) years old. The os acromiales were classified as edematous os acromiale or non-edematous os acromiale based on whether the presence of marrow edema, and as displaced os acromiale or non-displaced os acromiale based on whether the presence of displacement of the os acromiale. The MRI features of os acromiale were analyzed. Statistical analyses were performed to identify the differences between the os arcomiale group and no os arcomiale group regarding rotator cuff tear, supraspinatus and infraspinatus injury. Differences in the supraspinatus and infraspinatus tear between the edematous and non-edematous os acromiale group, the displaced and non-displaced os acromiale group, the displaced os acromiale and no os arcomiale group were also assessed.@*RESULTS@#On MRI, all the 21 os acromiales appeared as a triangular or irregular bone fragment of the distal acromion, and forms a pseudo-acromioclavicular joint with the acromion. Eleven cases were edematous os acromiale, 11 cases were displaced os acromiale. In the os arcomiale group, 17 had supraspinatus tear, 1 had supraspinatus tendinitis, 11 had infraspinatus tear, and 4 had infraspinatus tendinitis. In the no os arcomiale group, 11 had supraspinatus tear, 2 had supraspinatus tendinitis, 5 had infraspinatus tear, and 1 had infraspinatus tendinitis. No statistically significant difference between the os arcomiale group and no os arcomiale group regarding the rotator cuff tear, supraspinatus and infraspinatus injury (P>0.05). In the 11 cases of edematous os arcomiale, 10 had supraspinatus tear and 7 had infraspinatus tear. In the 10 cases of non-edematous os acromiale, 7 had supraspinatus tear and 4 had infraspinatus tear. No statistically significant difference was noted between the edematous os acromiale and non-edematous os acromiale in terms of supraspinatus and infraspinatus tear (P>0.05). In the 11 cases of displaced os acromiale, 11 had supraspinatus tear and 9 had infraspinatus tear. In the 10 cases of non-displaced os acromiale, 6 had supraspinatus tear and 2 had infraspinatus tear. In the no os arcomiale group, 11 had supraspinatus tear and 5 had infraspinatus tear. There was a statistically significant increases in the prevalence of supraspinatus and infraspinatus tear in the displaced os acromiale group compared with non-displaced os acromiale group, the displaced os acromiale group and no os arcomiale group(P<0.05).@*CONCLUSION@#Shoulder MRI can very well depict os acromiale and can reveal associated abnormalities such as adjacent bone marrow edema, displaced deformity, and rotator cuff tear, and it can be used to assess the stability of the os acromiale. The presence of os acromiale may not increase the risk of supraspinatus and infraspinatus tear significantly. However, the presence of displaced os acromiale is at greater risk of supraspinatus and infraspinatus tear.

OBJECTIVE@#To investigate the diagnostic value of 6 conventional physical examination tests for the diagnosis of supraspinatus tendon tears, and how well they could tell the difference between partial-and full-thickness tears.@*METHODS@#A total of 91 patients with different shoulder symptoms who received shoulder arthroscopic procedure were enrolled in the study from June 2017 to September 2020. The intraoperative findings were compared with the results of the preoperative physical examination of 6 clinical tests, including the Hug-up test, the Jobe test, the 0°abduction test, the drop arm test, the Neer test, and the Hawkins test, to determine the sensitivity, specificity, positive and negative predictive value, accuracy, positive and negative likelihood ratio of each test.@*RESULTS@#By arthroscopy, a total of 44 full-thickness tears, 34 partial-thickness tears, and 13 intact supraspinatus tendons were found in all 91 cases. The Hug-up and the Jobe tests significantly correlated with the intraoperative findings. The sensitivity of the Hug-up test, the Jobe test, the 0° abduction test, the drop arm test, the Neer test, and the Hawkins test was 0.90, 0.79, 0.64, 0.42, 0.49, 0.24 respectively;the specificity was 0.61, 0.69, 0.54, 0.38, 0.31, 0.77;the positive predictive value was 0.93, 0.94, 0.89, 0.80, 0.81, 0.86;the negative predictive value was 0.50, 0.36, 0.20, 0.10, 0.09, 0.14;the accuracy was 0.86, 0.78, 0.63, 0.42, 0.46, 0.32;the positive likelihood ratio was 2.30, 2.58, 1.39, 0.69, 0.71, 1.06;and the negative likelihood ratio was 0.16, 0.30, 0.67, 1.50, 1.65, 0.98.@*CONCLUSION@#The Jobe test and the Hug-up test are both effective at accurately diagnosing supraspinatus tendon tears, the Hug-up test detects supraspinatus tears with a high sensitivity, and similar specificity. The tests assessed in this study are not capable of distinguish between partial-and full thickness supraspinatus tendon tears.
