Differences in the arthroscopic treatment of anterior and posterior shoulder instability in long-term follow-up
Abstract
Background: Shoulder dislocations are frequent orthopedic injuries encountered in emergency services. Increasing the arthroscopic experience of physicians and developing technology has left the place of open surgical repair to arthroscopic reconstruction procedures. This study aimed to examine the results of arthroscopic reconstruction procedures for anterior and posterior shoulder instability.
Methods: In this study, 89 patients diagnosed with shoulder instability and treated arthroscopically in our clinic between January 1, 2013, and September 1, 2020, postoperative range of motion and functional results are evaluated with Rowe and WOSI scores.
Results: Fifty-seven of 89 patients had anterior, and 32 patients had posterior glenohumeral instabilities. In our study, 14 patients (15.7%) were under 20 years old, 55 patients (61.8%) between 21-30 years, 16 patients (18.0%) between 31-40 years, and 4 patients (4.5%) over 40 years. A total of 72 males (80.9%) were included in the study, with 17 females (19.1%). In the postoperative period, the mean shoulder joint flexion of all patients was recorded as 166.6 degrees, internal rotation 79.8 degrees, and external rotation was 79.9 degrees. The mean preoperative total WOSI score of all patients was 1062.6, whereas this score was 150.7 postoperatively. According to the Rowe score, there were poor results in all patients in the preoperative period, whereas the Rowe score of 70 patients was excellent; three patients were good, 11 patients were moderate, and five patients were poor in the postoperative period.
Conclusions: Arthroscopic treatment of glenohumeral instability could provide predictable success in unidirectional shoulder instability.
