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.
Objective To investigate arthroscopic treatment for acute acromioclavicular dislocation by using Twin Tail TightRope combined with distal joint capsular repair. Methods The clinical data of 40 patients with acromioclavicular dislocation treated between February 2016 and December 2017 were retrospectively analyzed. The patients were divided into arthroscopic group (20 cases, using arthroscopic Twin Tail TightRope combined with distal joint capsular repair for anatomical repair of stable structure of acromioclavicular joint) and control group (20 cases, treated with clavicular hook plate internal fixation) according to different surgical methods. There was no significant difference in gender, age, cause of injury, Rockwood classification, time from injury to operation, preoperative visual analogue scale (VAS) score and Constant score between the two groups (P>0.05), which were comparable. Postoperative VAS score and Constant score were used to assess shoulder function and re-dislocation was also observed. Results The incisions of the two groups healed by first intention, and no early postoperative complications occurred. All patients were followed up 12-18 months (mean, 13.5 months). Postoperative X-ray films showed good anatomical reduction in both groups, but the clavicular hook had a presense in the subacromial space in control group. All patients in arthroscopic group achieved satisfactory shoulder function and returned to work after operation; there was no obvious pain, no complications such as exposure of implant after operation, and no need to remove the implant. In the control group, 4 patients had obvious subacromial impingement pain after operation, and 1 patient had re-dislocation after removal of internal fixator at 1 year after operation; the rest had no complications related to internal fixation, and the internal fixators were removed at 1.0-1.5 years after operation, without re-dislocation. The VAS score and Constant score at 3 months and 1 year after operation in both groups significantly improved when compared with those before operation, and further improved at 1 year after operation (P<0.05). The VAS score and Constant score at 3 months and 1 year after operation in arthroscopic group were significantly better than those in control group (P<0.05). Conclusion Arthroscopic treatment for acute acromioclavicular joint dislocation by using Twin Tail TightRope combined with distal capsular repair is more effective than traditional incision surgery and can obtain more satisfactory results in patient compliance and function recovery because of minimally invasive surgery.
Objective To discuss the effectiveness of atlantoaxial joint release through anterior retrophayngeal approach and staged posterior reduction fixation and fusion for irreducible atlantoaxial dislocation (IAAD). Methods Fifteen patients with IAAD (9 males, 6 females), aged 14-53 years (mean, 31.4 years) were included in the study. The disease duration was 3 months to 17 years (mean, 5.7 years). IAAD was attributed to trauma in 13 cases, and 2 cases were caused by congenital odontoid disconnection. Preoperative imaging examination showed atlantoaxial dislocation and could not be reset automatically in functional position. The preoperative visual analogue scale (VAS) score was 3-7 (mean, 4.1), and the preoperative Japanese Orthopaedic Association (JOA) score was 10-17 (mean, 13.8). All patients received atlantoaxial joint release through anterior retrophayngeal approach and staged posterior fixation and fusion. Results Anatomical reduction was achieved in all 15 patients, and the alignment of atlantoaxial joints was restored. After operation, the neck pain and neurological symptom were partially or fully improved in all patients, without deterioration of neurological function. One patient developed pharyngeal discomfort and cough after one-stage operation, 4 patients developed pharyngeal discomfort and foreign body sensation after operation, and 2 patients developed pin-path lipstick swelling during skull traction. All patients were cured by symptomatic treatment. No pulmonary infection, pressure ulcers, venous thrombosis, and incision infection was found during the treatment. All 15 patients were followed up 24-36 months, with an average of 28.6 months. Bony fusion was achieved in all patients, and the fusion time was 3-5 months, with an average of 3.6 months. At last follow-up, the VAS score was 0-2 (mean, 0.5) and the JOA score was 13-17 (mean, 15.9). There was no dislocation, recurrence, or other abnormal sign in the cervical X-ray films and three-dimensional CT. Conclusion Anatomical reduction can be achieved by atlantoaxial joint release through anterior retrophayngeal approach and staged posterior fixation and fusion for treating IAAD. It is an optional procedure for IAAD.

The short head of the biceps brachii muscle was removed from its origin with a thin piece of bone from the coronoid process and was transposed to the dislocated clavicle. From the action of muscle contraction from the biceps brachii muscle, the dislocated clavicle would be pulled downward. This method of repair was satisfactory in4 cases of acromioclavicular dislocation. Results obtained from the follow-up, there was no recurrence of dislocation, and the function and muscle power of the shoulder were completely normal.
