Comparison of Muscle Energy Technique, Myofascial Release, and Combined Techniques for Glenohumeral Internal-Rotation Deficit. An Interventional Study / Comparación de Técnica de Energía Muscular, Liberación Miofascial y Técnicas Combinadas para el Déficit de Rotación Interna Glenohumeral. Un Estudio Intervencionista

SUMMARY: This study aimed to determine the benefits of a combined technique of muscle energy with and myofascial release more effective than using each in isolation in glenohumeral internal rotator deficits. An interventional study was designed for this study. Thirty-eight patients were diagnosed with painful shoulder syndrome. Patients were randomly allocated into 4 groups where Group A was treated with combined muscle energy and myofascial release; Group B with muscle energy technique; Group C with myofascial release and Group D used as control. The evaluation of the passive joint range of the glenohumeral internal rotation and sociodemographic data for each of the groups were measured, before and after interventions. Despite the use of myofascial release and muscle energy techniques being significantly beneficial in their respective groups, when both were combined; it outcomes were highly successful. A combination therapy treatment applied with the Muscle Energy and Myofascial Release Techniques in patients with painful shoulder syndrome will be more effective in increasing the range of motion of the glenohumeral internal rotation joint than any of the techniques applied individually.

Este estudio tuvo como objetivo determinar los beneficios de una técnica combinada de energía muscular con liberación miofascial más efectiva que usar cada una de manera aislada en los déficits de los músculos rotadores internos glenohumerales. Para este estudio se diseñó un protocolo de intervención. En 38 pacientes se diagnosticó síndrome de hombro doloroso. Los pacientes fueron asignados aleatoriamente a 4 grupos; el grupo A fue tratado con energía muscular combinada y liberación miofascial; Grupo B con técnica de energía muscular; Grupo C con liberación miofascial y Grupo D utilizado como control. Se midió la evaluación del rango articular pasivo de la rotación interna de la articulación glenohumeral y datos sociodemográficos de cada uno de los grupos, antes y después de las intervenciones. A pesar de que el uso de técnicas de liberación miofascial y energía muscular resultó significativamente beneficioso en sus respectivos grupos, cuando ambas se combinaron; Sus resultados fueron muy exitosos. Un tratamiento de terapia combinada aplicado con las Técnicas de Energía Muscular y Liberación Miofascial en pacientes con síndrome de hombro doloroso será más efectivo para aumentar el rango de movimiento de la articulación de rotación interna glenohumeral que cualquiera de las técnicas aplicadas individualmente.

Effects of glenosphere offsets on impingement-free range of motion in reverse total shoulder arthroplasty: a standardized computer simulation study / 中华创伤骨科杂志

Objective:To compare the effects of glenosphere offset positions on the impingement-free range of motion (ROM) in reverse total shoulder arthroplasty (RTSA).Methods:Shoulder joint models were reconstructed using shoulder CT scans of 6 patients with primary osteoarthritis. RTSA was performed virtually according to standard surgical procedures, and shoulder movements were simulated. Reverse shoulder models were constructed with 2 lateral offsets (0 and 4 mm) and 6 positional offsets (center, inferior, posterior, anterior, anterior-inferior, and posterior-inferior). The impingement-free ROM and impingement sites for abduction-adduction, flexion-extension, total rotation (sum of internal and external rotation), and total ROM (sum of ROM in all movement modes) were evaluated.Results:All the 12 combinations of different glenosphere offsets achieved 50% of the original shoulder ROM in all movements. In the abduction-adduction motion with 0 and 4 mm lateral offsets, the anterior-inferior offset provided the largest ROM (94.4°±8.7° and 105.3°±6.9°, respectively), but there was no significant difference between the positions ( P>0.05). In the flexion-extension motion with 0 and 4 mm lateral offsets, the posterior-inferior offset showed the largest ROM (194.1°±6.9° and 196.9°±9.7°, respectively), but there was no significant difference between the positions ( P>0.05). In the total rotation motion with 0 and 4 mm lateral offsets, the anterior-inferior offset had the largest ROM (141.5°±5.9° and 160.6°±8.5°, respectively), showing significant advantages over the center, anterior, and posterior offsets ( P<0.05), but insignificant advantages over the inferior and posterior-inferior offsets ( P>0.05). In total ROM, the anterior-inferior offset provided the largest ROM. When the lateral offset was 0 mm, the anterior-inferior offset provided a ROM of 421.8°±16.4°, showing significant advantages over the center and posterior offsets ( P<0.05). Compared with the lateral glenosphere offset of 0 mm, the lateral glenosphere offset of 4 mm significantly improved total shoulder ROM (122.8°±10.6° versus 145.8°±4.8°) and total ROM (390.9°±11.6° versus 428.4°±19.8°) ( P<0.05). Conclusions:The anterior-inferior, inferior, and posterior-inferior glenosphere offsets can improve ROM in all movement patterns. The position and lateral offset of the glenosphere significantly affect the total rotation and total ROM of the shoulder joint. Specifically, the anterior-inferior and inferior offsets show significant advantages over the center position in total rotation and total ROM of the shoulder joint.

Objective:To observe the clinical efficacy and safety of knee-balancing Tuina(Chinese therapeutic massage)manipulation for pes anserina bursitis(PAB). Methods:A total of 64 patients with PAB were enrolled and divided into a Tuina group and a medication group by the random number table method,with 32 cases in each group.The medication group was given votalin for external use,and the Tuina group was given knee-balancing Tuina manipulation based on treatment according to structure differentiation.Both groups were treated for 7 consecutive days.The visual analog scale(VAS)score,Lyshlom score,knee joint range of motion(ROM),and total effective rate were compared between the two groups.Adverse reactions were observed in both groups. Results:During the treatment,there was 1 dropout case in the medication group.The total effective rate was 93.8%in the Tuina group and 83.9%in the medication group.The difference between the two groups was statistically significant(P<0.05).After treatment,the VAS score in both groups decreased significantly(P<0.05),and the Lyshlom score and knee joint ROM increased significantly(P<0.05).The differences in the VAS score,Lyshlom score,and knee joint ROM between the two groups were all statistically significant(P<0.05). Conclusion:The knee-balancing Tuina manipulation based on treatment according to structure differentiation can effectively relieve pain and improve knee function in PAB,and its efficacy is superior to that of external use of votalin.

Glenosphere Size Does Not Matter in Reverse Total Shoulder Arthroplasty / O tamanho da glenosfera não importa na artroplastia total reversa de ombro

Abstract Objective There are few studies to date reporting on outcomes following reverse total shoulder arthroplasty with cohorts stratified by glenosphere size. The purpose of this study is to investigate the role that glenosphere size has on postoperative outcomes. Methods Patients who underwent reverse TSA between 1987 with minimum of 2.0 years of follow-up were included. Patients were stratified into two cohorts based on glenosphere size of 36mm or 40mm. Patients' range of motion, patient-reported outcomes, and radiographic variables (glenoid preoperative morphology, scapular notching, humeral loosening) were evaluated. Results All measurements of range of motion measurements with the exception of internal rotation saw significant preoperative to postoperative improvements within each cohort. There were no significant differences in postoperative range of motion, ASES, or VAS pain scores across the two cohorts. Overall, forward elevation improved to 134° ± 16° in the 36mm cohort and 133° ± 14° in the 40mm cohort (p = 0.47). External rotation improved to 37° ± 13° for 36mm patients and 35° ± 19° for 40mm patients (p = 0.58). In the 36mm group, internal rotation increased by 1.3 vertebral levels and 2.3 vertebral levels in the 40mm cohort. At final follow-up, the 36mm cohort had a VAS score of 2 ± 2, ASES score of 66 ± 19, and SST score of 6 ± 3. Similarly, the 40mm cohort had a VAS score of 2 ± 3, ASES score of 77 ± 28, and SST score of 9 ± 3. Conclusions Reverse TSA provides sustained improvements in range of motion and shoulder function irrespective of glenosphere size. Level of Evidence III.

Resumo Objetivo Até agora, poucos estudos relataram os desfechos da artroplastia total reversa (ATR) de ombro com coortes estratificadas pelo tamanho da glenosfera. O objetivo deste estudo é investigar o papel do tamanho da glenosfera nos desfechos pós-operatórios. Métodos O estudo incluiu pacientes submetidos à ATR de ombro desde 1987 com acompanhamento mínimo de 2,0 anos. Os pacientes foram estratificados em duas coortes com base no tamanho da glenosfera (36 mm ou 40 mm). A amplitude de movimento, os desfechos relatados pelo paciente e as variáveis radiográficas (morfologia pré-operatória da glenoide, incisura escapular e instabilidade do úmero) foram avaliados. Resultados Todas as medidas de amplitude de movimento, à exceção da rotação interna, melhoraram de forma significativa entre o período pré-operatório e pós-operatório nas duas coortes. Não houve diferenças significativas na amplitude de movimento pós-operatória, pontuação da American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) ou escala visual analógica (EVA) de dor entre as duas coortes. De modo geral, a elevação anterior melhorou para 134° ± 16° na coorte de 36 mm e 133° ± 14° na coorte de 40 mm (p = 0,47). A rotação externa melhorou para 37° ± 13° em pacientes da coorte de 36 mm e 35° ± 19° em pacientes da coorte de 40 mm (p = 0,58). A rotação interna aumentou 1,3 níveis vertebrais na coorte de 36 mm e 2,3 níveis vertebrais na coorte de 40 mm. No último acompanhamento, a coorte de 36 mm apresentou EVA de 2 ± 2, ASES de 66 ± 19 e pontuação do Simple Shoulder Test (SST) de 6 ± 3. Da mesma forma, a coorte de 40 mm teve EVA de 2 ± 3, ASES de 77 ± 28 e SST de 9 ± 3. Conclusões A ATR de ombro causa melhoras sustentadas da amplitude de movimento e função articular independentemente do tamanho da glenosfera. Nível de Evidência III.

Risk Factors for Symptomatic Cyclops Lesion Formation after Anterior Cruciate Ligament Reconstruction / Fatores de risco para formação de lesão cyclops sintomática após a reconstrução do ligamento cruzado anterior

Abstract Objective To evaluate the incidence of symptomatic cyclops lesions requiring surgical treatment after anterior cruciate ligament (ACL) reconstruction and to establish possible intraoperative risk factors related to it. Methods Three hundred and eighty-nine patients aged between 18 and 50 years who underwent primary ACL reconstruction were retrospectively evaluated. Patients were divided into groups according to the presence or absence of symptomatic cyclops lesions, and their characteristics were compared. Patients with associated lesions that required additional surgical procedures (except anterolateral extra-articular procedures) were not included. The rate of symptomatic cyclops lesions was recorded and the following parameters were evaluated: age, gender, time from injury to surgery, graft type and diameter, femoral tunnel perforation technique, fixation type, presence of knee hyperextension, preservation of the ACL remnant, associated anterolateral extra-articular procedure, associated meniscal injury and participation in sports. Results 389 patients were evaluated and 26 (6.7%) patients developed cyclops. The patients with and without cyclops lesions did not differ in age, time from injury to surgery, graft type or diameter, surgical technique, femoral fixation method, presence of knee hyperextension, remnant preservation and associated meniscal injury. The group with cyclops lesion had a higher proportion of females (10 (38.4%) vs 68 (18.7%); OR = 2.7; p= 0.015), higher proportion of extra-articular reconstruction (18 (11.8%) vs 8 (3.4%); OR = 3.8; p= 0.001) and higher proportion of sports practice (23 (8.6%) vs 3 (2.5%); OR = 3.6; p= 0.026). Conclusion In our series, 6.7% of the patients required arthroscopic removal of cyclops lesions. Female gender, associated extra-articular reconstruction and sports practice were factors related to this lesion. Remnant preservation had no relationship with cyclops lesion formation.

Resumo Objetivo Avaliar a incidência de lesões cyclops sintomáticas que precisam de tratamento cirúrgico após a reconstrução do ligamento cruzado anterior (LCA) e estabelecer os possíveis fatores de risco intraoperatórios relacionados a elas. Métodos Trezentos e oitenta e nove pacientes com idades entre 18 e 50 anos submetidos à reconstrução primária do LCA foram avaliados de forma retrospectiva. Os pacientes foram divididos em grupos de acordo com a presença ou ausência de lesões cyclops sintomáticas e suas características foram comparadas. Não foram incluídos pacientes com lesões associadas que necessitassem de outros procedimentos cirúrgicos (à exceção de procedimentos extra-articulares ântero-laterais). A taxa de lesões cyclops sintomáticas foi registrada e os seguintes parâmetros foram avaliados: idade, sexo, tempo da lesão à cirurgia, tipo e diâmetro do enxerto, técnica de perfuração do túnel femoral, tipo de fixação, presença de hiperextensão do joelho, preservação do LCA remanescente, associação a procedimento extra-articular ântero-lateral, lesão de menisco associada e participação em esportes. Resultados Dos 389 pacientes avaliados, 26 (6,7%) desenvolveram lesão cyclops. Os pacientes com e sem lesão cyclops não diferiram quanto à idade, tempo da lesão à cirurgia, tipo ou diâmetro do enxerto, técnica cirúrgica, método de fixação femoral, presença de hiperextensão do joelho, preservação do LCA remanescente e lesão de menisco associada. O grupo com lesão cyclops apresentou mais mulheres (10 [38,4%] vs. 68 [18,7%]; razão de probabilidades [OR] = 2,7; p= 0,015), maior proporção de reconstrução extra-articular (18 [11,8%] vs. 8 [3,4 %]; OR = 3,8; p= 0,001) e maior proporção de prática esportiva (23 [8,6%] vs. 3 [2,5%]; OR = 3,6; p= 0,026). Conclusão Em nossa série, 6,7% dos pacientes necessitaram de remoção artroscópica das lesões cyclops. O sexo feminino, a reconstrução extra-articular associada e a prática esportiva foram fatores relacionados a essa lesão. A preservação do menisco remanescente não foi associada à formação de lesões cyclops.

Evaluación de la movilidad de la dorsiflexión de tobillo en cadena cinemática cerrada / Assessment of ankle dorsiflexion range of motion in closed kinetic chain

RESUMEN Los esguinces laterales de tobillo (ELT) son las lesiones musculoesqueléticas más prevalentes entre sujetos que participan de actividades físicas y deportes. Además, hasta un 70% de la población general ha sufrido un ELT, el cual presenta la mayor tasa de reincidencia de todas las afecciones musculoesqueléticas de los miembros inferiores. Luego de un ELT, se ha registrado una limitación de la dorsiflexión de tobillo en cadena cinemática cerrada (CCC), movimiento representativo en tareas funcionales e influyente en el retorno al deporte. La prueba de estocada con carga de peso es utilizada para evaluar la dorsiflexión de tobillo en CCC y existen diferentes formas de realizarla. El objetivo de este paso a paso es describir dos formas de medición de la dorsiflexión de tobillo en CCC mediante el uso de aplicaciones móviles.

ABSTRACT Lateral ankle sprains (LAS) are the most prevalent musculoskeletal injuries among subjects participating in physical activities and sports. In addition, up to 70% of the general population has sustained a LAS, with the highest rate of recurrence of all musculoskeletal injuries in the lower limbs. Subjects with a history of LAS have limited ankle dorsiflexion range of motion in closed kinetic chain (CKC), which is a common movement during functional tasks and an essential movement in return to sports. The weight-bearing lunge test is used to assess ankle dorsiflexion range of motion in CKC and may be performed through different procedures. The objective of this study is to describe two procedures for measuring ankle dorsiflexion in CKC through the use of mobile applications.

ABSTRACT The shoulder joint has the greatest range of motion and is the most susceptible to dysfunction. Dynamic and quantitative evaluations of this region provide better information for the clinic but the choice of the method depends on its measurement properties. This study aimed to identify the existing methods of quantitative dynamic evaluation of the shoulder and scapula complex, in a clinical context for the general population, identifying the measurement properties and outcomes of each method. The scoping review included in vivo studies, with samples without a specific clinical condition and involving applicable methods in a clinical context. We identified evaluated outcome, measurement method, and its measurement properties. We selected 29 studies that investigated 12 measurement methods, and evaluated their validity and reliability for 17 different outcomes. Most studies (n=21) addressed the position of the shoulder and the scapula and the derivative outcomes, using mainly the units of inertial measurement (n=5) and inertial magnetic measurement (n=6) as evaluation methods. The outcomes with valid and reliable methods were: shoulder joint range; scapula and shoulder motion range; muscle activity; shoulder joint center; humerus length; torque-time curve; functional performance; scapular dyskinesia; external shoulder rotators force; shoulder joint functionality and range; initial scapular movement; scapula and shoulder position; and shoulder angular velocity.

Efeitos de um protocolo de aquecimento-alongamento-resfriamento sobre a flexibilidade muscular / Effects of a warm-up-cool-down protocol on muscle flexibility

Objetivo: Investigar os efeitos da associação entre alongamento e recursos termoterapêuticos sobre o ganho de flexibilidade e amplitude de movimento. Métodos: Este ensaio clínico, controlado, não randomizado e cego teve duração de três semanas, com duas sessões semanais e incluiu 27 indivíduos do sexo feminino, as quais compuseram tanto o grupo experimental quanto o controle, de forma que um de seus membros inferiores recebeu a intervenção terapêutica dos recursos termoterapêuticos e o membro oposto foi submetido apenas ao alongamento. A análise angular foi realizada através do software de avaliação postural Kinovera. Resultados: Os efeitos do alongamento associado ao calor prévio e resfriamento pós intervenção se mostraram mais eficazes comparado ao grupo controle pré-intervenção (p<0,000), grupo controle pós intervenção (p= 0,003) e grupo experimental pré-intervenção (p<0,000). Conclusão: A aplicação de calor prévio ao alongamento, seguido pelo emprego imediato de resfriamento propicia ganhos de flexibilidade muscular e amplitude de movimento maiores que o alongamento simples.

Objective: To investigate the effects between stretching and thermotherapeutics resources on gaining flexibility and range of motion. Methods: This controlled, non- randomized, blinded clinical trial lasted three weeks, with two weekly sessions and included 27 female individuals, who made up both the experimental and the control group, so one of their legs received therapeutic intervention from chemotherapeutic resources and the opposite one was submitted to stretching only. Angular analysis was performed using the Kinovera postural assessment software. Results: The effects of stretching associated with pre-intervention heat and post-intervention cooling were more effective compared to the pre-intervention control group (p<0.000), post- intervention control group (p= 0.003) and pre-intervention experimental group (p<0.000). Conclusion: The application of heat prior to stretching followed by immediate cooling provides gains in muscle flexibility and range of motion greater than simple stretching.

Fisioterapia após cirurgia de câncer de mama melhora a amplitude de movimento e a dor ao longo do tempo / La fisioterapia después de la cirugía de cáncer de mama mejora el rango del movimiento y el dolor a lo largo del tiempo / Physical therapy after breast cancer surgery improves range of motion and pain over time

RESUMO O tratamento do câncer de mama pode prejudicar a amplitude de movimento (ADM) e causar dor no membro superior (MS) homolateral. O objetivo deste estudo foi comparar a ADM, a intensidade e a caracterização da dor no MS homolateral à cirurgia entre as 1ª, 10ª e 20ª sessões de fisioterapia, além de correlacionar estas variáveis. Foi conduzido um ensaio clínico autocontrolado com a participação de 49 mulheres após cirurgia de câncer de mama que se queixavam de dor no MS. A ADM foi avaliada por meio de goniometria e o MS contralateral foi adotado como controle. A intensidade de dor foi avaliada pela escala visual analógica (EVA) e caracterizada pelo Questionário de McGill, obtendo-se o número de palavras escolhidas (NWC) e o índice de avaliação da dor (PRI). Verificou-se aumento significativo da ADM do MS homolateral ao longo das 20 sessões. Comparando o MS homolateral ao contralateral, somente a abdução não melhorou significativamente após a 20ª sessão. Observou-se uma redução significativa da intensidade de dor, do PRI e do NWC entre a 1ª e 10ª e entre a 1ª e 20ª sessão. As categorias sensorial e avaliativa também diminuíram significativamente. Foi encontrada uma correlação significativa entre EVA, PRI e NWC entre a 10ª e a 20ª sessão. A fisioterapia aumentou a ADM, reduziu a dor no MS homolateral e o número de palavras escolhidas para caracterizar a dor. Foram observadas melhoras expressivas no início do tratamento e ganhos adicionais ao longo do tempo. Exercícios para flexão, abdução e rotação externa bilaterais devem ser enfatizados no tratamento.

ABSTRACT Treatment of breast cancer can impair range of motion (ROM) and cause homolateral upper limb pain (UL). This study aimed to compare the ROM, intensity and characterization of UL homolateral pain between the 1st, 10th and 20th sessions of physiotherapy, besides correlating these variables. A clinical trial self-controlled study involving 49 women after mastectomy or quadrantectomy with pain complaint on UL was conducted. ROM was evaluated by goniometry and contralateral UL was adopted as control. The intensity of pain was evaluated by the visual analogue scale (VAS) and characterized by the McGill questionnaire, obtaining the number of words chosen (NWC) and the pain evaluation index (PRI). The ROM of the homolateral UL increased significantly over the 20 sessions. Comparing the homolateral UL with the control, only the abduction did not improve significantly after the 20th session. Pain intensity, PRI and NWC reduced significantly between 1st and 10th and between 1st and 20th sessions. The sensory and evaluative categories also decreased significantly. We observed a significant correlation between VAS, PRI and NWC in the 10th and 20th sessions. Physiotherapy increased ROM, reduced pain in the homolateral UL, and fewer words were chosen to characterize the pain. Significant improvements were observed at the beginning of treatment, but with additional gains over time. Exercises for bilateral flexion, abduction, and external rotation should be emphasized.

Efficacy and influential factors of opening wedge high tibial osteotomy for the treatment of knee osteoarthritis / 中国基层医药

Objective:To investigate the efficacy of opening wedge high tibial osteotomy (OWHTO) in the treatment of knee osteoarthritis, and analyze the related factors that affect its clinical efficacy.Methods:The clinical data of 80 patients with knee osteoarthritis who underwent OWHTO between December 2016 and May 2020 in Hospital of the Marine Police Corps of the Chinese People's Armed Police Force were retrospectively analyzed. These patients were divided into effective group ( n = 76) and ineffective group ( n = 4) according to clinical efficacy. The Visual Analogue Scale (VAS), the Hospital for Special Surgery Knee Score (HSS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) were used to assess the severity of knee osteoarthritis before and 3 months after surgery. The influential factors of clinical efficacy were analyzed. Results:VAS score, WOMAC score, HSS score, joint pain, joint function, joint range of motion, muscle strength, and flexion deformity of 80 patients post-surgery were improved compared with those pre-surgery ( t = 24.92, 21.45, 52.62, 15.87, 10.88, 15.28, 42.54, 11.07, all P < 0.05). After surgery, excellent outcomes were observed in 29 (36.25%) patients, good outcomes in 34 (42.50%) patients, fair outcomes in 13 (16.25%) patients, and poor outcomes in 4 (5.00%) patients. Body mass index, preoperative VAS score, and preoperative WOMAC score in the effective group were (24.10 ± 3.06) kg/m 2, (5.55 ± 1.57) points, and (36.96 ± 9.62) points, respectively, which were significantly lower than those in the ineffective group [(27.64 ± 3.62) kg/m 2, (7.87 ± 1.39) points, (47.95 ± 9.63) points, t = 2.23, 2.89, 2.22]. HSS score in the effective group was significantly higher than that in the ineffective group [(52.81 ± 3.71) points vs. (46.83 ± 3.69) points, t = 3.14, P < 0.05)]. Body mass index, preoperative VAS score, and preoperative WOMAC score were positively correlated with clinical efficacy ( r = 0.24, 0.31, 0.24, P < 0.05), and preoperative HSS score was negatively correlated with clinical efficacy ( r = -0.33, P < 0.05). Logistic regression analysis was performed to analyze the above markedly related factors. Preoperative HSS score was an independent protective factor of clinical efficacy of OWHTO, and body mass index and preoperative VAS score were risk factors of clinical efficacy of OWHTO. Conclusion:OWHTO can greatly improve knee function of patients with knee osteoarthritis and reduce postoperative pain. It should be noted that excessive obesity may affect the clinical efficacy of OWHTO, and preoperative VAS score and WOMAC score should be controlled in patients with excessive obesity.

A clinical study of posterior-medial dislocation of elbow joint / 中华骨科杂志

Objective:To analyze the clinical characters and results of the posteromedial dislocation of elbow.Methods:From January 2014 to March 2016, a retrospective observational study of 15 patients with posteromedial elbow dislocations was performed. There were twelve males and three females, the mean age was 44 years old (23-64 years old). There were fourteen complex dislocations and one simple dislocation. The signs of posteromedial dislocation included changes of carry angle and varus deformity. Dimple signs were found in 8 patients. Conservative treatment was used in two cases (one simple dislocation and one complex disclocation). Operative treatment was performed in the other 13 cases with complex dislocations, in which five were fixed by hinged external fixator due to instability. The ranges of elbow and forearm movement, visual analogue score (VAS) and Mayo elbow performance score (MEPS) were recorded before treatment and at the last visit after average 18 months (17-21 months) of follow-up.Results:Before treatment, the average arc of extension-flexion was 9.3°±1.3° (5°-15°), the average range of forearm pronation was 6.4°±1.4° (0°-10°), supination was 4.3°±1.7° (0°-10°); VAS averaged 8±0.3 scores (7-9 scores); MEPS averaged 15.7±4.3 scores (5-35 scores). At the last follow up, the average arc of extension-flexion was 105°±5.2° (90°-130°), the average range of forearm pronation was 60°±8.5° (20°-80°), supination was 76°±9.5° (20°-90°); VAS averaged 0.4±0.2 scores (0-1 score); MEPS averaged 95.7±2.3 scores (85-100 scores). Significant different was found in all index by paired t test ( P<0.001). No instability of elbow was found in physical and radiology test in all follow-up visit. Conclusion:Posteromedial dislocation of elbow is rare in clinics, closed reduction can be always successful in simple dislocations; open reduction would be necessary in the majority of complex dislocations. However, relatively satisfied clinical results could be achieved.

Objective:To investigate the effects of extracorporeal shock-wave therapy wave (ESWT) and ultrasound therapy on pain relief and lumbar mobility in patients with lumbar myofascial pain.Methods:A total of 100 patients with lumbar myofascial pain who received treatment in The First People's Hospital of Jiande from March 2020 to March 2021 were included in this study. They were randomly divided into ESWT and ultrasound therapy groups, with 50 patients per group. The ESWT group was treated with ESWT at a frequency of 8 Hz and an energy density of 0.16 mJ/mm 2 once a week. The ultrasound therapy group was treated with ultrasound therapy at a frequency of 1.0 MHz and an intensity of 1.0 W/cm 2, once a day, 5 times a week, for 4 consecutive weeks. Therapeutic effects, pain relief and lumbar mobility improvement were observed in each group. Results:Total response rate in the ESWT group was significantly higher than that in the ultrasound therapy group [92.00% (46/50) vs. 76.00% (38/50), χ2 = 4.76, P < 0.05). After treatment, Visual Analogue Scale (VAS) score and Oswestry Dysfunction Index (ODI) score in the ESWT group were (2.56 ± 1.03) points and (20.22 ± 3.45) points, respectively, which were significantly lower than (3.83 ± 1.12) points and (25.13±3.72) points ( t = 5.90, 6.84, both P < 0.001). After treatment, anterior flexion, posterior extension, and lateral flexion of the lumbar spine in the ESWT group were (68.32 ± 8.67)°, (51.13 ± 6.56)°, (69.43 ± 8.27)°, respectively, which were significantly higher than (61.65 ± 8.51)°, (47.22 ± 6.50)°, (64.16 ± 7.69)° in the control group ( t = 3.88, 2.99, 3.30, all P < 0.05). Conclusion:Compared with ultrasonic therapy, ESWT for lumbar myofascial pain can better relieve pain, improve lumbar mobility, and enhance clinical efficacy.
