Objective: To investigate the method and clinical effects of the treatment of recurrent shoulder dislocation with severe glenoid injury by arthroscopic subscapularis augmentation.
Methods: From March 2019 to August 2020, 16 patients with recurrent dislocation of shoulder with severe glenoid injury underwent arthroscopic subscapularis augmentation, including 10 males and 6 females, aged from 18 to 50 years old with an average of (29.06±10.54) years old, 4 cases of left shoulder and 12 cases of right shoulder.Visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score and Rowe score were used to evaluate shoulder function and stability before and after operation.
Results: All the 16 patients were followed up from 12 to 29 months, with an average of (18.75±7.26) months. VAS score decreased from 5.25±1.13 before operation to 1.37±0.65 at the final follow-up;ASES score increased from 59.44±9.93 before surgery to 90.88±4.00 at the final follow-up; Rowe score of shoulder increased from 51.56±8.89 before surgery to 92.19±7.06 at the final follow-up, and the differences were statistically significant (P<0.05). No dislocation was observed during follow-up. No clinical complications such as incision infection, vascular and nerve injury occurred in all patients after operation.
Conclusion: Arthroscopic subscapularis augmentation in the treatment of recurrent dislocation of shoulder with severe glenoid injury is satisfactory. It is an effective treatment method of recurrent dislocation of shoulder joint with severe glenoid injury, and external rotation function in patients with almost unaffected.
