Objective To study the treatment method and effect of abduction and lateral rotation l imitation of the shoulder in obstetric brachial plexus palsy (OBPP). Methods From February 2005 to August 2008, 11 patients with abduction and lateral rotation l imitation of the shoulder in OBPP were treated with dissection of the origin of subscapular muscle,transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. Among them, there were 6 males and 5 females with a mean age of 6 years (1-15 years). The main cl inical manifestations showed adduction, internal rotation contracture deformity of shoulder, l imited active and passive external rotation and severely restricted active abduction of shoulder. The passive abduction was more than 90°. According to Gilbert grading, there were 7 cases of grade 1 and 4 cases of grade 2. Based on Mallet score systems, the scores were 5 points in 3 cases, 6 points in 3 cases, and 7 points in 5 cases. The muscle strength of deltoid, supraspinatus, infraspinatus, teres major muscle and latissimus dorsi all reached 3-4 grades. Results One patient developed postoperative hematoma, wound healed after symptomatic management. Other patients achieved incision heal ing by first intention. All patients were followed up for 12 to 37 months (17 months on average). The active abduction and external rotation of the shoulder joints recovered obviously. The Gilbert grading were grade 2 in 1 case, grade 3 in 1 case, and grade 4 in 9 cases; the Mallet scores were 10 points in 1 case, 11 points in 2 cases, 12 points in 4 cases, 13 points in 3 cases, and 14 points in 1 case; showing significant differences when compared with those before operation(P lt; 0.01). The muscle strength of deltoid, supraspinatus, infraspinatus, teres major muscle and latissimus dorsi increased to 4-5 grades. Conclusion The dissection of the origin of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles can resolve shoulder adduction, internal rotation contracture, and can enhance abduction, external rotation strength. It is an effective operation for abduction and lateral rotation l imitation of the shoulder in OBPP.

Methods A total of 120 patients with shoulder periarthritis diagnosed in our hospital between April 2007 and June 2008 were randomly divided into treatment group and control group with 60 in each group. Patients in the treatment group were treated with dense silver needle acupuncture therapy combined with brachial plexus nerve block, while patients in the control group were only treated with dense silver needle acupuncture therapy. Results In the treatment group, 43 patients were cured, the treatment produced effect in 15 patients, and improvement could be found in two patients. For the control group, those three numbers were respectively 41, 16 and 3. The effectice rate was 100% in both groups. The difference of effect between the two groups was not statistically significant (Pgt;0.05), while the variation of blood pressure and heart rate and the visual analogue scales in the treatment group were significant lower than these in the control gvroup (Plt;0.05) Conclusion The dense silver needle acupuncture therapy combined with brachial plexus nerve block is safe and effective in treating old patients with shoulder periarthritis.
Objective To review the research progress of ultrasound in the diagnosis and treatment of shoulder diseases, in order to provide a theoretical basis for the further development of ultrasound in shoulder surgery. Methods The recent literature on the application of ultrasound in the shoulder joint was extensively reviewed. The application of ultrasound in the diagnosis and treatment of shoulder joint diseases, and the advantages and disadvantages of ultrasound were analysed, and the development trend of ultrasound technology in the shoulder joint area was prospected. Results At present, the diagnosis of shoulder joint diseases mainly relies on MRI, however, with the development of ultrasound technology, ultrasound with the characteristics of convenient, reliable, and real-time dynamic evaluation is more and more recognized in the diagnosis process of shoulder joint diseases, combined with three-dimensional ultrasound, ultrasound intervention, and elastography can improve the accuracy, sensitivity, and specificity of the diagnosis, and is suitable for the diagnosis and treatment of various shoulder joint diseases, which is expected to carry out early prevention of shoulder joint diseases in the future and achieve more refined and minimally invasive treatment. ConclusionUltrasound technology has wide application prospect in shoulder joint diseases, but it is still in the developing stage, and the subjective dependence needs to be solved further.
Objective To review the research progress of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation, and provide a guide for further research on bone graft resorption. Methods The relevant literature in recent years was extensively reviewed. The pathogenesis, classification, risk factors, clinical function impact, and management of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation were summarized. Results Bone graft resorption is the common complication after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation. Stress shielding and poor blood supply may contribute to the occurrence of bone graft resorption. The absence of significant preoperative glenoid bone loss, open procedure, earlier graft healing may to be the risk factors for bone graft resorption. Various assessment methods and classification systems are used to evaluate the region and severity of bone graft resorption. Partial resorption may be considered as a natural glenoid remodeling process after the surgery, but severe and complete resorption is proved to be one of the reasons for failed procedures and there is no effective measure to prevent it, except for accepting revision surgery. Conclusion The pathogenesis, risk factors, clinical function impact of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation has not been fully elucidated and there is a lack of effective management strategies, so further clinical and basic researches are needed.
Objective To investigate the effectiveness of arthroscopic autologous iliac bone grafting with double-row elastic fixation in treatment of recurrent anterior shoulder dislocation combined with massive glenoid bone defects. Methods Between January 2018 and December 2021, 16 male patients with recurrent anterior shoulder dislocation combined with massive glenoid bone defects were treated with arthroscopic autogenous iliac bone grafting and double-row elastic fixation. The patients were 14-29 years old at the time of the first dislocation, with an average age of 18.4 years. The causes of the first dislocation included falling injury in 5 cases and sports injury in 11 cases. The shoulders dislocated 4-15 times, with an average of 8.3 times. The patients were 17-37 years old at the time of admission, with an average age of 25.1 years. There were 5 left shoulders and 11 right shoulders. The preoperative instability severity index (ISIS) score of the shoulder joint was 5.8±2.1, and the Beighton score was 4.3±2.6. The University of California Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score were used to evaluate shoulder function, and the degree of the glenoid bone defect repair was observed based on CT after operation. Results All incisions healed by first intention, and no complication such as incision infection or neurovascular injury occurred. The patients were followed up 12 months. At 12 months after operation, UCLA score, Constant score, ASES score, and Rowe score all significantly improved when compared with the scores before operation (P<0.05). CT imaging showed the degree of glenoid bone defect was significantly smaller at immediate, 6 and 12 months after operation when compared with that before operation (P<0.05), and the bone blocks healed with the scapula, and bone fusion had occurred at 12 months. ConclusionArthroscopic autologous iliac bone grafting with double-row elastic fixation is a safe treatment for recurrent anterior shoulder dislocation combined with massive glenoid bone defects, with good short-term effectiveness.
Objective To simulate anterosuperior instabil ity of the shoulder by a combination of massive irreparable rotator cuff tears and coracoacromial arch disruption in cadaveric specimens, use proximally based conjoined tendon transfer forcoracoacromial l igament (CAL) reconstruction to restrain against superior humeral subluxation, and investigate its feasibility and biomechanics property. Methods Nine donated male-adult and fresh-frozen cadaveric glenohumeral joints were applied to mimic a massive irreparable rotator cuff tear in each shoulder. The integrity of the rotator cuff tendons and morphology of the CAL were visually inspected in the course of specimen preparation. Cal ipers were used to measure the length of the CAL’s length of the medial and the lateral bands, the width of coracoid process and the acromion attachment, and the thickness in the middle, as well as the length, width and thickness of the conjoined tendon and the lateral half of the removed conjoined tendon. The glenohumeral joints were positioned in a combination of 30° extension, 0° abduction and 30° external rotation. The value of anterosuperior humeral head translation was measured after the appl ication of a 50 N axial compressive load to the humeral shaft under 4 sequential scenarios: intact CAL, subperiosteal CAL release, CAL anatomic reattachment, entire CAL excision after lateral half of the proximally based conjoined tendon transfer for CAL reconstruction. Results All specimens had an intact rotator cuff on gross inspection. CAL morphology revealed 1 Y-shaped, 4 quadrangular, and 4 broad l igaments. The length of the medial and lateral bands of the CAL was (28.91 ± 5.56) mm and (31.90 ± 4.21) mm, respectively; the width of coracoid process and acromion attachment of the CAL was (26.80 ± 10.24) mm and (15.86 ± 2.28) mm, respectively; and the thickness of middle part of the CAL was (1.61 ± 0.36) mm. The length, width, and thickness of the proximal part of the proximally based conjoined tendon was (84.91 ± 9.42), (19.74 ± 1.77), and (2.09 ± 0.45) mm, respectively. The length and width of the removed lateral half of the proximally conjoined tendon was (42.67 ± 3.10) mm and (9.89 ± 0.93) mm, respectively. The anterosuperior humeral head translation was intact CAL (8.13 ± 1.99) mm, subperiosteal CAL release (9.68 ± 1.97) mm, CAL anatomic reattachment (8.57 ± 1.97) mm, and the lateral half of the proximally conjoined tendon transfer for CAL reconstruction (8.59 ± 2.06) mm. A significant increase in anterosuperior migration was found after subperiosteal CAL release was compared with intact CAL (P lt; 0.05). The translation after CAL anatomic reattachment and lateral half of the proximally conjoined tendon transfer for CAL reconstruction increased over intact CAL, though no significance was found (P gt; 0.05); when they were compared with subperiosteal CAL release, the migration decreased significantly (P lt; 0.05). The translation of lateral half of the proximally conjoined tendon transfer for CAL reconstruction increased over CAL anatomic reattachment, but no significance was evident (P gt; 0.05). Conclusion The CAL should be preserved or reconstructed as far as possible during subacromial decompression, rotator cuff tears repair, and hemiarthroplasty for patients with massive rotator cuff deficiency. If preservation or the insertion reattachment after subperiosteal release from acromion of the CAL of the CAL is impossible, or CAL is entirely resected becauseof previous operation, the use of the lateral half of the proximally based conjoined tendon transfer for CAL reconstruction isfeasible.
OBJECTIVE: To study the reconstructional method and effect of shoulder joint function in the older obstetrical palsy with medial rotation contracture deformity. METHODS: From April 1996 to July 1999, 7 patients of older obstetrical palsy were adopted in this study. Among them, there were 5 males and 2 females, aged from 13 to 21 years old. No previous operation history and the main deformity was medial rotation contracture of shoulder. During operation, these patients were treated with "Z"-shape elongation of the tendon of subscapular muscle, transfer of the tendons of latissimus dorsi and teres major muscle to the tendons of supraspinous and infraspinous muscles. RESULTS: Followed up for 6 to 44 months(averaged 19 months), the Gilbert grading and Mallet scoring were 1.57, 7.57 preoperatively versus 3.45, 10.86 postoperatively, the abduction and external rotation of the shoulder joints recovered obviously. CONCLUSION: It is an effective operation for the older obstetrical palsy with medial rotation contracture of shoulder.
Objective To investigate the mid-term effectiveness of arthroscopic Bankart repair for recurrent anterior shoulder dislocation. Methods The clinical data of 107 patients with recurrent anterior shoulder dislocation who met the inclusion criteria between January 2017 and June 2021 was retrospectively analyzed, and all patients underwent arthroscopic Bankart repair. There were 88 males and 19 females. The age of the primary dislocation ranged from 13 to 48 years (mean, 23.3 years). The number of preoperative dislocations was 2-160 times (median, 7 times). The duration of preoperative instability was 0.2-240.0 months (median, 36.0 months). The mean age at operation was 28.2 years (range, 16-61 years). There were 43 cases of left shoulder and 64 cases of right shoulder. The proportion of glenoid defects in 63 patients was 1.7%-16.1% (mean, 8.1%). MRI showed that none of the patients had rotator cuff tears or shoulder stiffness. The CT three-dimensional reconstruction was performed at 1 day after operation to evaluate the distribution of implanted anchors and the occurrence of glenoid split fracture and whether there were nails pullout at the implant site. The postoperative complications were observed, and the pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, Rowe score, Constant-Murley score, and American Shoulder and Elbow Surgeons (ASES) score. The recurrence of instability, the results of apprehension test, the number of patients who returned to preoperative sports level, and the satisfaction rate of patients were recorded. Results All patients were successfully operated and were followed up 20-73 months (mean, 41.5 months). All incisions healed by first intention. The CT three-dimensional reconstruction at 1 day after operation showed that the anchors were located at the 2 : 00-5 : 30 positions of the glenoid, and there was no glenoid split fracture or nails pullout at the implant site. At last follow-up, VAS score was significantly lower than that before operation, and Rowe score, Constant-Murley score, and ASES score were significantly higher than those before operation (P<0.05). Seven patients (6.5%) had recurrence of anterior shoulder dislocation at 23-55 months (mean, 39.9 months) after operation, including 6 cases of dislocation and 1 case of subluxation. At last follow-up, 51 patients (47.7%) returned to preoperative sports level, and 11 patients (10.3%) had a positive apprehension test. The patients’ satisfaction rate was 90.7% (97/107). Among the 10 patients who were not satisfied with the surgical effectiveness, 7 patients had postoperative recurrence of instability, and 3 patients felt that they did not return to preoperative sports level. Conclusion Arthroscopic Bankart repair has good mid-term effectiveness in patients with recurrent anterior shoulder dislocations, minimal or no glenohumeral bone defects and low sports need.
