Purpose Of The StudyThere are few reports onlong-term outcome after Bankart procedure. The purpose of this study was to determine the rate of recurrent dislocation, the clinical results and the incidence of glenohumeral osteoarthritis after a minimum 10-year follow-up.Material And MethodsNinety-seven Bankart procedures were performed in 97 patients between 1972 and 1986 for treatment of anterior shoulder instability with recurrent dislocations. We retrospectively reviewed 74 patients and obtained 64 complete radioclinical evaluations for an average follow-up of 16 years. Clinical evaluation was based on the G. Walch and the Duplay group score but for easier comparisons, we also calculated the Rowe et al. score. Radiographical evaluation was established on the Samilson and Prieto classification but real glenohumeral osteoarthritis with joint narrowing was noted independently as grade four. We also studied the contralateral shoulder.ResultsAt last follow-up, 7 shoulders (9.5%) had recurrent dislocation, but two of them occurred subsequent to severe trauma over 18 months. Most patients (95 %) were satisfied or very satisfied. Six patients (8.1%) had persistent apprehension but in some it was not due to anterior apprehension. According to the Duplay score (or the Rowe score), 25 shoulders (44.6%) had an excellent result (35/61.4 %) 16 (28.6%) a good result (7/12.3%), 11 (19.7%) a fair result (11.19.3) and 4 (5.4 %) a poor result (4/7%). Operated shoulders were pain free for 75% and painful for forced movements only for 25%. External rotation at 90 degrees of abduction was reduced by 8.7 +/- 15.7 degrees. There was no limitation of internal rotation. Patients returned to preoperative sports activities at the same level for 70.9 % and at a lower level for 12.7%. According to the Samilson classification, 7 (13%) of the shoulders had grade 2 and 2 (3.7%) had grade 3 glenohumeral osteoarthritis. We found 4 cases (7.4%) of real glenohumeral osteoarthritis (grade four) and 2 of these patients had contralateral osteoarthritis of a non unstable shoulder. There was no perioperative complication.DiscussionIn our hands the Bankart procedure is appeared as a safe procedure with a low rate of glenohumeral osteoarthritis and a high rate of patient satisfaction.
