Objective To investigate the method and effectiveness of coracoplasty with mini-incision for subcoracoid impingement syndrome. Methods Between May 2006 and September 2011, 4 patients with subcoracoid impingement syndrome were treated, including 3 cases of congenital dysplasia of the coracoid process and 1 case of anterior glenohumeral instability. There were 3 males and 1 female with an average age of 36 years (range, 20-56 years). The disease duration was 6-22 months (mean, 11.2 months). The patients had a history of chronic pain and click of the anterior should, which was aggravated in adduction, internal rotation, and flexion. The results of the coracoid impingement test were positive by Neer and Hawkins-Kennedy impingement sign. The axial CT in adduction position showed that the coracohumeral interval decreased and coracoid index increased. The 2 cm lateral coracoid incision was made and the 0.5-1.5 cm coracoid neck was revealed and cut by osteotomy. The coracoplasty was performed by amputating the conjoined tendon insertion of the short head of the biceps and the coracobrachialis muscle and suturing to proximal coracoid osteotomy surface. Shoulder was fixed with the external braces for 6 weeks. Results Healing of incision by first intention was observed in all cases without any complication. All the 4 patients were followed up from 8 months to 5 years. At last follow-up, pain and click disappeared. The mean visual analogue scale (VAS), University of California at Los Angeles (UCLA), Constant, and simple shoulder test (SST) scores were significantly improved from 7.75, 10.25, 65.50, and 9.75 at preoperation to 0.25, 34.25, 91.25, and 0.25 at last follow-up respectively. The axial CT in adduction position and MRI showed that long coracoid process was removed; the coracohumeral interval was increased to 13.38 mm from 4.16 mm at preoperation; and the coracoid index was decreased to 0.28 mm from 13.08 mm at preoperation. Conclusion Coracoplasty with mini-incision is an effective method to relieve clinical symptoms of subcoracoid impingement, which has less complications and faster recovery.
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 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).MethodsExtensive 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 evaluate the early-term effectiveness of Latarjet procedure with double EndoButtons fixation for recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament. Methods Between January 2021 and June 2023, 19 patients with recurrent anterior shoulder dislocations were treated by arthroscopic Latarjet procedure with double EndoButtons fixation, all of which underwent coracoid osteotomy with preserving the coracoacromial ligament. There were 11 males and 8 females, with an average age of 23.3 years (range, 17-32 years). Shoulder dislocations ranged from 3 to 11 times, with an average of 6.4 times. The disease duration ranged from 3 to 35 months, with an average of 12.9 months. All apprehension tests were positive. Imaging examination showed that the defect width of the ipsilateral glenoid bone was 13%-26%, with an average of 19.8%. After operation, the shoulder range of motion was examined, including flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation. Shoulder joint function was evaluated by Walch-Duplay score, American Association for Shoulder and Elbow Surgery (ASES) score, and Rowe score. Imaging examinations were taken to observe the position and shaping of coracoid. Results All incisions healed by first intention and no nerve or vessel injury occurred. All patients were followed up 9-24 months (mean, 14.5 months). There was no recurrence of shoulder dislocation and the apprehension tests were negative during follow-up. There was no significant difference in the shoulder range of motion (flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation) between preoperation and at last follow-up (P>0.05). The Walch-Duplay score, ASES score, and Rowe score significantly improved when compared with those before operation (P<0.05). Postoperative imaging showed that coracoid graft was at the same level with the glenoid in all cases; the center of coracoid graft was located between 3 to 5 o’clock. During follow-up, there was no glenohumeral joint degeneration, the acromiaohumeral distance was not reduced when compared with preoperation, and the coracoid bone gradually formed concentric circles with the humeral head. Conclusion The Latarjet procedure with double EndoButtons fixation can effectively treat recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament, and the early-term effectiveness is satisfactory.
Objective To investigate the early effectiveness of the limited unique coracoid osteotomy suture button fixation Latarjet (LU-tarjet)-congruent-arc (CA) technique (LU-tarjet-CA) in treating recurrent shoulder dislocations with huge glenoid defect. Methods The clinical data of 12 patients with recurrent shoulder dislocation and huge glenoid defect who met the selection criteria and treated with arthroscopic LU-tarjet-CA between January 2021 and December 2023 were retrospectively analyzed. The cohort included 8 males and 4 females, aged 20-40 years with an average age of 30.4 years. The range of glenoid bone loss was 30%-40%, with an average of 35.5%. The time from symptom onset to hospital admission ranged from 1 to 36 months, with an average of 18.5 months. The University of California Los Angeles (UCLA) score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and Rowe score were used to evaluate shoulder function preoperatively and at 3, 6, and 12 months postoperatively. CT three-dimensional (3D) reconstruction was used to assess coracoid healing and plasticity at 3, 6, and 12 months postoperatively. Subjective satisfaction of patient was recorded at last follow-up. Results All incisions healed by first intention, with no incision infection or nerve injury. All 12 patients were followed up 12 months. One patient developed Propionibacterium acnes infection within the joint postoperatively and recovered after initial arthroscopic debridement and anti-inflammatory treatment. At 3 months after operation, CT 3D-reconstruction showed 1 case of complete coracoid absorption; neither of these two patients experienced redislocation. The remaining patients exhibited partial coracoid absorption but displayed local reshaping, filling the preoperative defect area, and bony fusion between the coracoid and the glenoid. At last follow-up, 9 patients (75%) were very satisfied with the outcome, and 3 patients (25%) were satisfied; the satisfied patients experienced postoperative shoulder stiffness caused by suboptimal functional exercise but did not have impaired daily life activities. The UCLA score, ASES score, Walch-Duplay score, and Rowe score at 3, 6, and 12 months postoperatively were significantly better than preoperative scores, and each score improved further over time postoperatively, with significant differences between different time points (P<0.05). Conclusion The arthroscopic LU-tarjet-CA technique for treating recurrent shoulder dislocations with huge glenoid defect can achieve the surgical objective of bony blockade and filling bone defects to prevent shoulder dislocation, thereby improving patients’ quality of life and shoulder joint function and stability.
