Promising outcomes seen with arthroscopic osseous Bankart repair
This 5-year to 8-year follow-up study showed arthroscopic osseous Bankart repair is efficacious for patients with greater than 15% loss of the inferior glenoid diameter and can provide normalized glenoid morphology as well as low rates of dislocation.
Investigators studied 46 patients with substantial glenoid bone loss who underwent arthroscopic osseous Bankart repair for treatment of traumatic anterior glenohumeral instability. Final follow-up data at a mean of 6.2 years was available for 38 patients. Investigators evaluated shoulder function with the Rowe rating scale and Western Ontario Shoulder Instability Index (WOSI). At the final follow-up, forward flexion, external rotation with the arm at the side, external rotation at 90° abduction and vertebral level of internal rotation were evaluated. Glenoid bone loss was calculated with the use of 3-D CT images.
Overall, the mean Rowe score significantly improved from 30.7 points preoperatively to 95.4 points postoperatively. WOSI scores also significantly improved significantly from 26.5% to 81.5%.
According to investigators, the glenoid bone fragment averaged 4.7%, which was significantly smaller compared with the glenoid bone loss. Mean glenoid bone loss improved from preoperative to postoperative values.
At 5 months after surgery, one patient had a redislocation due to a traffic accident which caused displacement of the osseous fragment. Investigators noted within 1 year after surgery, all patients with the exception of one patient had returned to sports at the same level or higher. ‒ by Monica Jaramillo
