ABSTRACT

In 2013, midpalatal suture maturation stage assessment was proposed for the evaluation of patients before performing maxillary expansion. In this study, we aimed to analyze the association between the midpalatal suture maturation stages assessed by CBCT, according to the method described by Angelieri et al., and other objective methods used to assess skeletal maturation or bone fusion. A computerized database search was conducted using PubMed, Cochrane Library, SciELO, LILACS, Web of Science, and Scopus, without language restriction. Unpublished literature was searched on ClinicalTrials.gov, the National Research Register, and Pro-Quest Dissertation Abstracts and Thesis database. Authors were contacted when necessary, and reference lists of the included studies were screened. Search terms included midpalatal suture, maturation, correlation, diagnostic performance, classification, evaluation, assessment, and relationship. Quality assessment was performed using the Observational Cohort and Cross-Sectional Studies tool developed by the National Heart, Lung, and Blood Institute. Eleven studies met the inclusion criteria. Of all the studies included, 81.9% had fair qualit y and 18.1% good quality, respectively. Eight out of eleven studies assessed the correlation between the midpalatal suture maturation method and the skeletal maturity evaluated by CVM method (Spearman's correlation coefficient: 0.244-0.908). Two out of eleven studies evaluated the correlation between midpalatal suture maturation method and the skeletal maturity assessed by HWM method (Spearman's correlation coefficient: 0.904-0.905) Even though midpalatal suture maturation stage assessment needs an exhaustive training and calibration process, it is a valid method to evaluate skeletal maturation or bone fusion. From a clinical perspective, for patients at CS4, CS5 and CS6, an assessment of the midpalatal suture on CBCT is indicated. A similar assessment should be done in patients at SMI 7-9.


En 2013, se propuso un nuevo método para la evaluación del estadio de maduración de la sutura palatina mediana para la evaluación de los pacientes antes de realizar la expansión maxilar. En este estudio, nuestro objetivo fue analizar la asociación entre las etapas de maduración de la sutura palatina mediana evaluada en CBCT, según el método descrito por Angelieri et al., y otros métodos objetivos utilizados para evaluar la maduración esquelética o la fusión ósea. Se realizó una búsqueda en las bases de datos PubMed, Cochrane Library, SciELO, LILACS, Web of Science y Scopus, sin restricción de idioma. Se buscó literatura no publicada en ClinicalTrials.gov, el Registro Nacional de Investigación y la base de datos Pro-Quest Dissertation Abstracts and Thesis. Se estableció contacto con los autores cuando fue necesario y se revisaron las listas de referencias de los estudios incluidos. Los términos de búsqueda incluyeron sutura palatina mediana, maduración, correlación, rendimiento diagnóstico, clasificación, evaluación, valoración y relación. La evaluación de la calidad se realizó mediante la herramienta de Estudios transversales y de cohortes observacionales desarrollada por el Instituto Nacional del Corazón, los Pulmones y la Sangre. Once estudios cumplieron con los criterios de inclusión. Del total de estudios incluidos, el 81.9% tuvo calidad regular y el 18.1% calidad buena, respectivamente. Ocho de once estudios evaluaron la correlación entre el método de maduración de la sutura palatina mediana y la madurez esquelética evaluada por el método CVM (coeficiente de correlación de Spearman: 0.244-0.908). Dos de once estudios evaluaron la correlación entre el método de maduración de la sutura palatina mediana y la madurez esquelética evaluada por el método HWM (coeficiente de correlación de Spearman: 0.904-0.905). Aunque la evaluación del estado de maduración de la sutura palatina mediana necesita un proceso exhaustivo de entrenamiento y calibración, es un método válido para evaluar la maduración esquelética o la fusión ósea. Desde una perspectiva clínica, para pacientes en CS4, CS5 y CS6, está indicada una evaluación de la sutura palatina mediana en CBCT. Se debe realizar una evaluación similar en pacientes con SMI 7-9.

ABSTRACT

OBJECTIVE@#To explore the effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament (PCL) tibial insertion fractures in adults.@*METHODS@#Between October 2019 and October 2021, 16 patients with PCL tibial insertion fractures were treated with arthroscopic binding fixation using suture through single bone tunnel. There were 11 males and 5 females with an average age of 41.1 years (range, 26-58 years). The fractures were caused by traffic accident in 12 cases and sports in 4 cases. The time from injury to operation ranged from 2 to 10 days with an average of 6.0 days. The fractures were classified as Meyers-McKeever type Ⅱ in 4 cases and type Ⅲ in 9 cases, and Zaricznyi type Ⅳ in 3 cases. There were 2 cases of grade Ⅰ, 7 cases of grade Ⅱ, and 7 cases of grade Ⅲ in the posterior drawer test. There were 3 cases combined with lateral collateral ligament injury and 2 cases with meniscus injury. The visual analogue scale (VAS) score, Lysholm score, International Knee Documentation Committee (IKDC) score, and knee range of motion were used to evaluate knee joint function. The posterior drawer test and knee stability tester (Kneelax 3) were used to evaluate knee joint stability. The X-ray films were used to evaluate fracture reduction and healing.@*RESULTS@#All incisions healed by first intention after operation. There was no incision infection, popliteal neurovascular injury, or deep venous thrombosis of lower limbs. All patients were followed up 6-12 months, with an average of 10 months. X-ray films at 6 months after operation showed the fractures obtained bone union. There were 11 cases of grade 0, 4 cases of gradeⅠ, and 1 case of grade Ⅱin posterior drawer test, showing significant difference when compared with preoperative results ( Z=23.167, P<0.001). The VAS score, Lysholm score, IKDC score, knee range of motion, and the results of Kneelax3 examination all significantly improved when compared with preoperative results ( P<0.05).@*CONCLUSION@#For adult patients with PCL tibial insertion fractures, the arthroscopic binding fixation using suture through single bone tunnel has the advantages of minimal trauma, good fracture reduction, reliable fixation, and fewer complications. The patient's knee joint function recovers well.

ABSTRACT

OBJECTIVE@#To investigate the feasibility and effectiveness of "tail compression fixation+suture bridge" technology under shoulder arthroscopy for treating primary tear in medial enthesis of rotator cuff.@*METHODS@#The clinical data of 11 patients with primary tear in medial enthesis of rotator cuff who met the selection criteria between October 2020 and October 2022 were retrospectively analyzed, including 3 males and 8 females, aged 39-79 years, with an average of 61.0 years. Rotator cuff injury was caused by traumatic fall in 8 cases, and the time from injury to admission was 1-4 months, with an average of 2.0 months; the remaining 3 cases had no obvious inducement. The active range of motion of the affected shoulder was limited, with an active forward flexion range of motion of (64.1±10.9)°, abduction of (78.1±6.4)°, internal rotation of (48.2±6.6)°, and external rotation of (41.8±10.5)°; 5 cases had shoulder stiffness. The preoperative visual analogue scale (VAS) score was 7.8±0.8 and the American Society of Shoulder and Elbow Surgeons (ASES) score was 23.9±6.4. The patients were treated with "tail compression fixation+suture bridge" technology under shoulder arthroscopy, and the pain and functional recovery were evaluated by VAS score, ASES score, and active range of motion of shoulder joint at last follow-up; MRI was performed after operation, and the integrity of rotator cuff was evaluated by Sugaya classification system.@*RESULTS@#All the 11 patients were followed up 2-22 months, with an average of 13.5 months. All incisions healed by first intention, and there was no complication such as infection, rotator cuff re-tear, and anchor falling off. At last follow-up, the VAS score was 0.8±0.7 and the ASES score was 93.5±4.2, which significantly improved when compared with those before operation ( P<0.05). All 11 patients had no significant swelling in the shoulders, and the active range of motion was (165.1±8.8)° in flexion, (75.3±8.4)° in abduction, (56.6±5.5)° in internal rotation, and (51.8±4.0)° in external rotation, which significantly improved when compared with those before operation ( P<0.05). Shoulder MRI showed adequate tendon thickness and good continuity in 9 cases, including 4 cases with partial high signal area; and 2 cases with inadequate tendon thickness but high continuity and partial high signal area. According to Sugaya classification system, there were 4 cases of type 1 (36.4%), 5 cases of type 2 (45.5%), and 2 cases of type 3 (18.1%).@*CONCLUSION@#For the patients with primary tear in medial enthesis of rotator cuff, the "tail compression fixation+suture bridge" technology under shoulder arthroscopy is simple and effective.

ABSTRACT

OBJECTIVE@#To explore the effectiveness and advantages of using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair compared with traditional arthroscopic suture shuttle.@*METHODS@#The clinical data of 41 patients with Bankart lesion, who met the selection criteria and were admitted between August 2019 and October 2021, was retrospectively analyzed. Under arthroscopy, the inferior capsulolabral complex was stitched with Fastpass Scorpion suture passer in 27 patients (FS group) and with arthroscopic suture shuttle in 14 patients (ASS group). There was no significant difference between the two groups ( P>0.05) in gender, age, injured side, frequency of shoulder dislocation, time from first dislocation to operation, and preoperative Rowe score of shoulder. Taking successful suture and pull-tightening as the criteria for completion of repair, the number of patients that were repaired at 5∶00 to 6∶00 (<6:00) and 6∶00 to 7∶00 positions of the glenoid in the two groups was compared. The operation time, and the difference of Rowe shoulder score betwee pre- and post-operation, the occurrence of shoulder joint dislocation, the results of apprehension test, and the constituent ratio of recovery to the pre-injury movement level between the two groups at 1 year after operation.@*RESULTS@#Both groups completed the repair at 5∶00 to 6∶00 (<6∶00), and the constituent ratio of patients completed at 6∶00 to 7∶00 was significantly greater in the FS group than in the ASS group ( P<0.05). The operation time was significantly shorter in the FS group than in the ASS group ( P<0.05). All incisions in the two groups healed by first intention. All patients were followed up 12-36 months (mean, 19.1 months). No anchor displacement or neurovascular injury occurred during follow-up. Rowe score of shoulder in the two groups significantly improved at 1 year after operation than preoperative scores ( P<0.05), and there was no significant difference in the difference of Rowe shoulder score between pre- and post-operation between the two groups ( P>0.05). At 1 year after operation, no re-dislocation occurred, and there was no significant difference in the apprehension test and the constituent ratio of recovery to the pre-injury movement level between the two groups ( P>0.05).@*CONCLUSION@#Compared with the arthroscopic suture shuttle, using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair is more convenient, saves operation time, and has good effectiveness.

ABSTRACT

OBJECTIVE@#To investigate the feasibility and effectiveness of fascial tissue flaps and skin flaps with layered sutures for repairing wounds after excision of sacrococcygeal pilonidal sinus.@*METHODS@#Between March 2019 and August 2022, 9 patients with sacrococcygeal pilonidal sinus were admitted, including 7 males and 2 females with an average age of 29.4 years (range, 17-53 years). The disease duration ranged from 1 to 36 months, with a median of 6 months. There were 7 cases with obesity and dense hair, 3 cases with infection, and 2 cases with positive bacterial culture of sinus secretion. The wound area after excision ranged from 3 cm×3 cm to 8 cm×4 cm, with a depth of 3-5 cm, reaching the perianal or caudal bone; there were 2 cases with perianal abscess formation and 1 case with caudal bone inflammatory edema. Enlarged resection was performed during operation, and the fascial tissue flap and skin flap were designed and excised at both left and right sides of the buttock, ranging from 3.0 cm×1.5 cm to 8.0 cm×2.0 cm. A cross drainage tube was placed at the bottom of the wound, and the fascial tissue flap and skin flap were advanced and sutured in three layers, namely, 8-string sutures in the fascial layer, barbed wire reduction sutures in the dermis, and interrupted skin sutures.@*RESULTS@#All 9 patients were followed up 3-36 months, with an average of 12 months. All incisions healed by first intention, and no complication such as incisional dehiscence or infection in the operative area occurred. There was no recurrence of sinus tracts, the shape of gluteal sulcus was satisfactory, both sides of buttocks were symmetrical, local incision scar was concealed, and the shape disruption was minimal.@*CONCLUSION@#Fascial tissue flaps and skin flaps with layered sutures for repairing wounds after excision of sacrococcygeal pilonidal sinus can effectively fill the cavity and reduce the incidence of poor incision healing, with the advantages of small trauma and simple operation.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of "hybrid" suture with en masse combined with double-layer repair under arthroscopy in repair of delaminated rotator cuff tear by comparison with en masse suture.@*METHODS@#Fifty-six patients with delaminated rotator cuff tears met selection criteria between June 2020 and January 2022 were included in the study. Patients were divided into two groups ( n=28) using a random number method. The patients in trial group underwent arthroscopic "hybrid" suture with the combination en masse and double-layer suture. The patients in control group underwent en masse suture under arthroscopy. There was no significant difference between the two groups ( P>0.05) in terms of gender, age, rotator cuff tear side, tear size, cause of injury, disease duration, and preoperative American Association of Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) shoulder scoring, visual analogue scale (VAS) score, and shoulder range of motion (forward flexion and lateral external rotation). The operation time, the difference of ASES score, UCLA score, VAS score, and shoulder range of motion (forward flexion and lateral external rotation) between pre- and post-operation were recorded and compared between the two groups ( P>0.05). The rotator cuff healing was examined by MRI and evaluated based on the classification criteria of rotator cuff healing proposed by Sugaya et al.@*RESULTS@#Three cases (1 case in the trial group and 2 cases in the control group) were excluded from the study due to loss of follow-up. Twenty-seven cases in the trial group and 26 cases in the control group were included in the final study analysis. All operations of the two groups were completed successfully. There was no significant difference in the operation time between groups ( P>0.05). The follow-up time was 10-12 months (mean, 10.9 months) in the trial group and 10-13 months (mean, 11.4 months) in the control group. All incisions healed by first intention. No surgery-related complications occurred. The UCLA score, ASES score, VAS score, and shoulder range of motion (forward flexion and lateral external rotation) of both groups at 9 months after operation were significantly superior to those before operation ( P<0.05). The difference of UCLA score, ASES score, and VAS score between before and after operation in the trial group were significantly better than those in the control group ( P<0.05). There was no significant differences between the two groups in the difference of shoulder range of motion (forward flexion and lateral lateral rotation) ( P>0.05). At 9 months after operation, according to the classification criteria of rotator cuff healing proposed by Sugaya et al, MRI showed that the rotator cuff healing of the trial group was significantly better than that of the control group ( P<0.05).@*CONCLUSION@#Compared with en masse suture, arthroscopic "hybrid" suture for the repair of delaminated rotator cuff tear has advantages in relieving pain and improving shoulder joint function, and the rotator cuff healing is better.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of double pulley combined with suture bridge in the treatment of comminuted fracture of the lower pole of the patella.@*METHODS@#From January 2018 to June 2020, 15 patients with comminuted fracture of the lower pole of the patella were treated with double pulley and suture bridge technology, including 9 males and 6 females, aged 28 to 68 years old with an average of (42.4±9.6) years old. All patients had obvious knee joint pain and limited movement after injury. All knee joints were examined by X-ray and CT, which confirmed that they were all comminuted fractures at the lower level of the patella. After operation, X-ray films of the knee joint were taken regularly to understand the fracture healing, the Insall Salvati index was measure, the range of motion of the joint was recorded, and the function of the knee joint was evaluateed by the Bostman scoring system.@*RESULTS@#All the 15 patients were followed up for 7 to 24 months with an average of (11.4±4.2) months, and there was no obvious anterior knee pain. At the last follow-up, the knee joint range of motion of the affected limb was 105° to 140° with an average of (128.5±12.8) °, and the Insall Salvati index was 0.79 to 1.12 with an average of (0.92±0.18). The X-ray film showed that the patella was bone healing, and no anchor fell off, broken, or displaced fracture block was found. Bostman patellar fracture function score was 27.85±2.06, 13 cases were excellent, 2 cases were good.@*CONCLUSION@#Double pulley technique combined with suture bridge technique is reliable for reduction and fixation of comminuted fracture of the lower pole of patella, and patients can start functional exercise early after operation.

ABSTRACT

Introducción: La sutura meniscal es una técnica cada vez más utilizada en pacientes con lesiones meniscales, con buenos resultados en la población general. Sin embargo, los estudios realizados en pacientes deportistas son escasos. Se analizaron las fallas de la sutura meniscal y el retorno al deporte en pacientes deportistas, y se identificaron posibles factores asociados. Materiales y Métodos: Se evaluaron retrospectivamente 61 suturas meniscales en deportistas (puntaje de Tegner ≥6) con un seguimiento mínimo de 12 meses. Cuarenta y nueve eran lesiones aisladas y 12 se asociaban con plástica del ligamento cruzado anterior. El seguimiento promedio fue de 61 meses y los pacientes fueron evaluados con los puntajes de Tegner y de Lysholm. Resultados: Se constató la falla de la sutura meniscal en 12 (19,67%) pacientes; la falla ocurrió, en promedio, 14 meses poscirugía. Nueve fallas se produjeron en suturas aisladas y 3 se asociaron con plástica del ligamento cruzado anterior (p <0,05). El menisco que más falló fue el interno. El 75% corresponde a pacientes que practicaban un deporte de contacto y pivote (p <0,05). Los pacientes que no sufrieron falla pudieron continuar con la misma actividad deportiva que antes de la lesión y el puntaje de Lysholm había mejorado significativamente (p <0,05). Conclusiones: Las fallas fueron significativamente más frecuentes en meniscos internos, suturas aisladas, lesiones en asa de balde, y deportes de contacto y pivote. Consideramos que la sutura meniscal es una excelente opción quirúrgica para pacientes deportistas, ya que un alto porcentaje de ellos retorna al deporte. Nivel de Evidencia: IV


Introduction: Meniscal suturing is a technique increasingly used in patients with meniscal lesions, with good outcomes in the general population. However, research on athletes is limited. Meniscal suture failures and return to sport in athletes were analy-zed, and possible contributing factors were identified. Materials and Methods: Sixty-one meniscal sutures in athletes (Tegner score ≥6) with a minimum follow-up of 12 months were retrospectively evaluated. Forty-nine were isolated lesions and 12 were associated with anterior cruciate ligament reconstruction. The average follow-up was 61 months and patients were evaluated with Tegner and Lysholm scores. Results: Meniscal suture failure was noted in 12 (19.67%) patients; failure occurred, on average, 14 months post-surgery. Nine failures occurred in isolated sutures and 3 were associated with anterior cruciate ligament recons-truction (p<0.05). The meniscus that failed the most was the internal meniscus. Seventy-five percent corresponded to patients who practiced pivot-contact sports (p<0.05). Patients who did not suffer failure were able to continue with the same sporting activity as before the injury and the Lysholm score had significantly improved (p<0.05). Conclusions: Failures were significantly more frequent in internal menisci, isolated sutures, bucket-handle injuries, and pivot-contact sports. We believe that meniscal suture is an excellent surgical option for athletic patients because a high percentage of them return to sports. Level of Evidence: IV

ABSTRACT

OBJECTIVE@#To evaluate the early and mid-term clinical results of medial parapatellar soft tissue overlapping suture in total knee arthroplasty for treatment of severe osteoarthritis combined with permanent patellar dislocation.@*METHODS@#We retrospectively analyzed the data of 12 patients (12 knees) diagnosed with severe knee osteoarthritis combined with permanent patellar dislocation undergoing total knee arthroplasty with medial parapatellar soft tissue overlapping suture. Knee Society Score (KSS), University of California Los Angeles (UCLA) activity-level rating, Visual Analog Scale (VAS) pain score, and knee range of motion of the patients were assessed before and 2 years after the surgery. Anteroposterior and lateral radiographs of the knee joint, full-length standing radiographs of the lower limbs and patellar axial radiographs were evaluated.@*RESULTS@#The mean Knee Society Score of the patients increased from 34.2±11.1 before surgery to 73.5±6.3 at two years after the surgery (P < 0.001). The UCLA activity-level rating increased from an average of 3.8 ± 0.8 before surgery to 5.8 ± 0.6 at two years postoperatively (P=0.003). The mean VAS pain score decreased from 42.8±6.0 before surgery to 20.1±3.7 (P < 0.001) and the range of motion of the knee joint increased from 74.6±8.9 degrees to 97.5±4.5 degrees at two years (P < 0.001). The radiographs showed no signs of subluxation or dislocation of the patella in all the patients.@*CONCLUSIONS@#Medial parapatellar soft tissue overlapping suture in total knee arthroplasty can achieve good early and mid-term clinical results for treatment of severe osteoarthritis combined with permanent patellar dislocation.

ABSTRACT

OBJECTIVE@#To assess three-dimensional (3D) changes of circummaxillary sutures following maxillary protraction with alternate rapid palatal expansions and constrictions (RPE/C) facemask protocol in maxillary retrusive children, and to investigate the relationship between the changes of circum-maxillary sutures and zygomaticomaxillary suture (ZMS) maturation, and to explore the factors of maxilla forward movement with RPE/C and facemask.@*METHODS@#In the study (clinical trial registration No: ChiCTR2000034909), 36 maxillary retrusive patients were recruited and block randomized to either the rapid palatal expansion (RPE) group or the RPE/C group. Patients aged 7 to 13 years, Class Ⅲ malocclusion, anterior crossbite, ANB less than 0°, Wits appraisal less than -2 mm, and A-Np less than 0 mm were included in the study. The RPE group received rapid palatal expansion, whereas the RPE/C group received alternate rapid palatal expansions and constrictions, and both with facemask protraction. Head orientations of cone-beam computed tomography (CBCT) images were implemented by Dolphin 11.7. 3D measurements of circummaxillary sutures on CBCT images were evaluated using Mimics 10.01 before (T0) and after treatment (T1). The changes were analyzed with independent t test, two-way ANOVA, Pearson correlation and regression analysis.@*RESULTS@#Two subjects in the RPE/C group were lost to follow-up. A total of 34 patients reached the completion criteria and were analyzed. Compared with the RPE group, sagittal changes of circummaxillary sutures were significantly increased in the RPE/C group with 1.21 mm advancement of zygomaticotemporal suture, 2.20 mm of ZMS, 1.43 mm of zygoma-ticofrontal suture (P < 0.05, respectively). Except for the zygomaticotemporal suture, the rest forward sagittal changes of other circummaxillary sutures showed no major difference in terms of the ZMS maturation. The Spearman's correlation in RPE/C indicated a strong positive correlation of sagittal changes between ZMS and point A (P < 0.01) with a regression analysis R2=42.5%.@*CONCLUSION@#RPE/C might be more effective on the treatment of maxillary retrusive children. As one of the major mechanical loading sutures during orthopedic therapy, ZMS showed a strong positive correlation with point A on sagittal changes.

ABSTRACT

Surgical stabilization of the flail chest is challenging and has no established guidelines. Chest wall integrity and stability are the main factors that ensure the protection of intrathoracic organs and an adequate respiratory function. Here, we report a novel chest wall reconstruction technique in a 45-year-old man with a traumatic left flail chest and open pneumothorax diagnosed both clinically and radiographically. Rib approximation and chest wall reconstruction was done using intercostal figure-of-eight suture and polypropylene mesh with vascularized musculofascial flap. The patient improved gradually and was discharged after three weeks of total hospital stay. He returned to regular working after a month with no evidence of respiratory distress or paradoxical chest movement. Follow-up visit at one year revealed no lung hernia or paradoxical chest movement. This is a novel, feasible and cost-effective modification of chest wall reconstruction that can be adopted for thoracic wall repair in case of open flail chest, which needs emergency surgical interventions even in resource constraint settings.

ABSTRACT

OBJECTIVE@#To investigate the effect of suture of pronator muscle on forearm function after modified Henry approach for distal radius fractures.@*METHODS@#from January 2018 to December 2020, 220 patients with distal radius fractures were treated with open reduction and locking plate internal fixation through the modified Henry approach. They were divided into two groups according to different suture methods. There were 112 cases in the intraoperative suture group, including 35 males and 77 females;The age ranged from 37 to 65(48.5±7.4) years;AO classification of fracture, 46 cases of type B and 66 cases of type C;After fracture reduction and locking plate fixation, the pronator muscle was opened and sutured. There were 108 cases in the non suture group, 32 males and 76 females;The age ranged from 34 to 67(47.6±7.8) years;There were 41 cases of fracture type B and 67 cases of fracture type C;After fracture reduction and locking plate fixation, the open pronator muscle was not sutured, and it was laid on the surface of the plate in situ. The range of wrist motion (pronation, supination, palmar inclination and dorsiflexion), the score of disability of arm shoulder and hand dash and visual analog scale(VAS) were compared between the two groups at 6 weeks and 6 months after operation.@*RESULTS@#All 220 patients were followed up for 6 to 18 (8.5±1.3) months. There was no significant difference in the range of motion and DASH score of forearm and wrist between the two groups 6 weeks after operation (P>0.05);There was significant difference in VAS score between suture group (2.6±1.2) and non suture group (5.8±2.3)(P<0.05). Six months after operation, there was no significant difference in the range of motion, DASH score and VAS score of forearm and wrist between the two groups(P>0.05).@*CONCLUSION@#The modified Henry approach has no obvious advantages in the range of wrist movement and upper limb function, but the intraoperative suture of pronator can reduce the early postoperative pain. It is suggested that the pronator should be sutured during the operation.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of scar tissue suture at the broken end of Achilles tendon after gastrocnemius aponeurosis release in the treatment of chronic Achilles tendon rupture.@*METHODS@#The clinical data of 17 patients with old achilles tendon rupture treated from January 2017 to December 2019 were analyzed retrospectively, including 15 males and 2 females, aged 26 to 53 years with an average of (35.2±11.6) years old, and the time from injury to operation was 37 to 92 days with an average of (49.3±13.3) days. Myerson's classification included 6 cases of typeⅡ and 11 cases of typeⅢ. The defect of the broken end of Achilles tendon was 2 to 5 cm with an average of(4.1±1.5) cm after partial scar tissue was removed. All patients were treated with gastrocnemius aponeurosis, appropriate excision of scar tissue at the broken end of Achilles tendon and direct suture. The continuity and healing of Achilles tendon were evaluated by color Doppler ultrasound 3 months after operation. The ankle plantar flexor strength was measured by ankle plantar flexor strength tester before operation and 1 year after operation. American Orthopaedic Foot and Ankle Society ankle hindfoot score (AOFAS) and Achilles tendon rupture score were used before operation and 1 year after operation Achilles tendon total fracture score (ATRS) was used to evaluate the clinical rehabilitation of Achilles tendon rupture.@*RESULTS@#All patients were followed up for 12 to 18 months with an average of(13.6±1.8) months. The surgical incision healed in stageⅠ. Color Doppler ultrasound showed good continuity of Achilles tendon, local Achilles tendon slightly thickened and irregular fiber direction. The ankle plantar flexor force (92.2±3.9) N at 1 year after operation was significantly higher than that before operation (29.5±4.2) N (P<0.05);One year after operation, the AOFAS(91.20±3.30) was significantly higher than that before operation (42.20±4.40)(P<0.05);the ATRS (90.70±3.00) was significantly higher than that before operation(40.00±2.90)(P<0.05).@*CONCLUSION@#The gastrocnemius aponeurosis release combined with scar suture of Achilles tendon end is an effective technique for the treatment of chronic Achilles tendon rupture, avoid injury to hallux flexor longus or flexor digitorum longus, with the plantar flexor muscle strength of the ankle was recovered well, is an effective method to treat chronic Achilles tendon rupture.

ABSTRACT

Introducción Aunque diferentes materiales y técnicas se han desarrollado para el cierre superficial y profundo en reemplazo total de rodilla (RTR), no hay evidencia que permita dar recomendaciones respecto a una técnica especifica que disminuya complicaciones postoperatorias de la herida. El propósito de este estudio es comparar el uso de dos técnicas de cierre profundo (Sutura barbada vs. Sutura absorbible trenzada) y superficial (grapas vs. sutura de polipropileno) en RTR. Materiales y métodos Estudio observacional retrospectivo en 240 pacientes. Se excluyeron pacientes con antecedente de cirugía abierta previa de rodilla, RTR previo por lesiones tumorales o artrofibrosis. Seguimiento mínimo de 1 año. Resultados Se usaron grapas en 176 pacientes y Prolene® en 64 pacientes. El cierre profundo se realizó con Stratafix® en 164 pacientes y con Vicryl® en 75 pacientes. Encontramos complicaciones relacionadas con la herida y la funcionalidad al año de seguimiento. La infección superficial para el cierre con prolene presento un HR de 2.6 con un intervalo de confianza (IC) de 95%=1.1-6.2; p=0.029 y en el cierre profundo encontramos un HR a favor del Vicryl® de 0.22, IC 95%=0.96-5.8; p=0.05. Conclusiones Este estudio demostró un incremento significativo de la incidencia de infección superficial después de un RTR cuando el cierre profundo se realiza con suturas barbadas y el cierre superficial se realiza con sutura de polipropileno. Sin embargo, no se presentaron diferencias significativas en otras complicaciones relacionadas con la herida y en la funcionalidad postoperatoria con las diferentes técnicas de cierre superficial y profundo evaluadas.


Introduction Different materials and techniques have been developed for superficial and deep closure in total knee replacement (TKR), but there is no solid evidence that allows to recommend a specific technique that decreases the surgical post-operative complications. The purpose of this study is to compare the use of two deep closure techniques (barbed suture vs. braided absorbable suture) and superficial (staples vs. polypropylene suture) in TKR. Materials and methods An observational retrospective study was carried out in 240 patients. Those individuals were excluded with previous open knee surgery, arthrofibrosis, patients who underwent TKR due to tumor lesions or a follow up for less than one year. Results The skin was closed in 176 patients with staples and in 64 patients with Prolene®. Deep closure was performed with Stratafix® in 164 patients and with Vicryl® in 75 patients. Also, complications related to the wound and functionality were recorded in the first postoperative year. Superficial infection for closure with prolene presented an HR in favor of 2.6 with a confidence interval (CI) of 95%=1.1­6.2; p=0.029 and in deep closure a HR in favor of Vicryl® of 0.22, 95% CI=0.96­5.8; p=0.05 Conclusions This study demonstrated a significant increase in the incidence of superficial infection after TKR when deep closure is performed with barbed sutures and superficial closure with polypropylene suture. However, there were no significant differences in other complications related with the wound neither postoperative functionality with the different superficial and deep closure techniques that were evaluated.
