OBJECTIVETo investigate the shoulder function after arthroscopic reduction and internal fixation in patients with bony Bankart lesion.

METHODSBetween May 2004 and May 2008, 45 patients with bony Bankart lesion who were treated with all arthroscopic reduction and internal fixation with metal anchors were included in this study. Among them 40 patients were male and 5 patients were female. The average age at the surgery was 27.6 years (16.5 - 50.1 years). The average duration of follow-up was 29.7 months (24.8 - 49.0 months). A history of recurrent dislocation of affected shoulder was found in all patients. Metal anchors were used to fix the bony Bankart lesion during the surgery. Hill-Sachs remplissage technique was used to treat the Engaging Hill-Sachs lesion. The preoperative American Shoulder and Elbow Society (ASES) score, Constant-Murley score, Rowe score and the VAS score for instability were 84 ± 14, 95.1 ± 4.6, 39.4 ± 2.9 and 5 ± 3 respectively.

RESULTSNo significant change was found regarding active forward elevation, external rotation and internal rotation after the surgery. The ASES score, Constant-Murley score, Rowe score and the VAS score of stability were 95 ± 7, 98.3 ± 2.2, 84.5 ± 22.0 and 1 ± 2, improved significantly higher after the surgery (P < 0.01). One subluxation and 3 redislocation were happened during follow-up. The overall failure rate was 8.9% (4/45).

CONCLUSIONSAll arthroscopic reduction and fixation of bony Bankart lesion can achieve a good result.
