Abstract
OBJECTIVE: To evaluate the effectiveness of arthroscopic Pushlock anchor fixation with iliac creast bone autograft in the treatment of recurrent anterior shoulder instability with critical bone defect. METHODS: The clinical data of 80 patients with recurrent anterior shoulder instability with critical bone defect treated by arthroscopic Pushlock anchor fixation with iliac creast bone autograft between January 2016 and January 2019 were retrospectively analyzed. The patients were all male; they were 18-45 years old at the surgery, with an average of 25 years old. The disease duration ranged from 3 months to 5 years, with an average of 2 years. The shoulder joint dislocated 3-50 times, with an average of 8 times. X-ray films, MRI, CT scans and three-dimensional reconstruction of the shoulder were performed before operation. The area of the anterior glenoid defect was 25%-45%, with an average of 27.3%. The shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score were used to evaluate the shoulder function before operation and at last follow-up. RESULTS: Patients were followed up 1-3 years, with an average of 2 years. No shoulder dislocation occurred again during follow-up. All partial graft absorption occurred after operation, CT scan showed that the graft absorption ratio was less than 30% at 1 week and 3 months after operation. CT three-dimensional reconstruction at 1 year after operation showed that all grafts had healed to the glenoid. The anterior glenoid bone defect was less than 5% (from 0 to 5%, with an average of 3.2%). At last follow-up, the shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score significantly improved when compared with preoperative ones ( P<0.05). The shoulder mobility of external rotation in abduction at 90° of the affected side limited when compared with the healthy side [(6.7±5.1)°]. CONCLUSION: Arthroscopic Pushlock anchor fixation with iliac creast bone autograft has a good effectiveness in the treatment of recurrent anterior shoulder instability with critical bone defect. The method is relatively simple and the learning curve is short.
