Objective: To explore the research progress of the coracoid transfer surgery using suture button fixation, particularly focusing on the technique known as Chinese unique Inlay Bristow (Cuistow surgery)., Methods: Extensive literature review was conducted to summarize and analyze the utilization of suture button fixation in the Cuistow surgery, comparing its biomechanical and clinical outcomes with those of traditional screw fixation., Results: Utilizing suture button fixation in coracoid transfer surgery helps circumvent certain metal-related complications associated with traditional screw fixation. While its biomechanical stability and effectiveness have been preliminarily confirmed, debates persist regarding its graft healing rate and postoperative recurrence rate compared to traditional screw fixation. The Cuistow surgery based on the Inlay structure is a solution to improve the healing rate of graft after suture button fixation., Conclusion: Suture button fixation, as a novel approach in coracoid transfer surgery, remains to have its advantages and disadvantages compared to traditional screw fixation not entirely elucidated, underscoring the need for further in-depth clinical and fundamental research. Cuistow surgery is the Chinese experience of coracoid transfer surgery, and its biomechanical stability and clinical advantages have been preliminarily confirmed.

Objective: To review the research progress of the biomechanical study of the Bristow-Latarjet procedure for anterior shoulder dislocation., Methods: The related biomechanical literature of Bristow-Latarjet procedure for anterior shoulder dislocation was extensively reviewed and summarized., Results: The current literature suggests that when performing Bristow-Latarjet procedure, care should be taken to fix the bone block edge flush with the glenoid in the sagittal plane in the direction where the rupture of the joint capsule occurs. If traditional screw fixation is used, a double-cortical screw fixation should be applied, while details such as screw material have less influence on the biomechanical characteristics. Cortical button fixation is slightly inferior to screws in terms of biomechanical performance. The most frequent site of postoperative bone resorption is the proximal-medial part of the bone block, and the cause of bone resorption at this site may be related to the stress shielding caused by the screw., Conclusion: There is no detailed standardized guidance for bone block fixation. The optimal clinical treatment plan for different degrees of injury, the factors influencing postoperative bone healing and remodeling, and the postoperative osteoarticular surface pressure still need to be further clarified by high-quality biomechanical studies.

Objective: To discuss and evaluate the diagnose and surgical techniques of rotator cuff tear with arthroscopic repair and its clinical results., Methods: From November 2006 to April 2008, 22 patients with rotator cuff tear were treated by arthroscopic repair using 5 different methods. There were 13 males and 9 females, aged 28-51 years old (mean 37.9 years old). The locations were left shoulder in 6 cases and right shoulder in 16 cases. Eleven cases underwent shoulder joint injury and other 11 cases had no inducement. According to Bigliani acromion classification, there were 12 cases of type II and 10 cases of type III. There were 5 bursa-side tear, 3 articular-side tear, and 14 full thickness tear. The disease course was 5 months to 6 years (mean 16.6 months). After all the patients underwent acromioplasty, 4 cases were treated by debridement of rotator cuff, 7 cases by single roll suture anchor, 4 cases by double suture anchors, 3 cases by triple suture anchors, and 4 cases by transosseous technique suture., Results: Incision healed by first intention and no complications occurred in all patients. Twenty-two cases were followed up 12-26 months (mean 15.6 months). The active forward flexion and abduction at the last follow-up were over 150 degrees in 21 cases, 90-120 degrees in 1 case. Postoperatively, the forward flexion strength was grade 5 in 20 cases and grade 4 in 2 cases. The score of University of California Los Angeles, the pain score, the function score, the forward flexion score, the forward flexion strength were improved significantly when compared with preoperation (P < 0.05). The results were excellent in 13 cases and good in 9 cases, the excellent and good rate was 100%., Conclusion: Depending on the correct diagnoses, 5 different methods of rotator cuff repair are used according to the different changes of shoulders, the outcome is good in all cases.
