Abstract
We evaluated the effectiveness of arthroscopic repair in patients with shoulder instability owing to a bony fragment as part of the Bankart lesion, using spiked Suretacs, sutures and anchors.
Over a two-year period, we followed up 23 of 25 consecutive cases, all with a bony fragment as part of the Bankart lesion. The mean age of patients, all of whom were male, was 21 years (17 to 35). Almost all injuries were sustained playing sports. Patients were clinically evaluated at six weeks and 20 weeks postoperatively and interviewed telephonically.
Full arthroscopic examination was performed in a lateral decubitus position. The affected capsular structures and labrum, with its attached bony fragment, were fully mobilised. The bony fragment was always attached to the capsular structures, with labral ring intact. We used a spiked Suretac anchor to reattach the bony fragment to its original anatomical position, and Mitek anchors and no. 1 Ticron sutures for individual reattachment of the capsule and ligaments. Postoperatively patients were immobilised in a shoulder sling for six weeks. Early restricted active and passive movements were advised. Patients routinely received postoperative physical and biokinetic rehabilitation. The mean follow up period was 16 months (5 to 29). There was no redislocation or subjective instability.
This technique yields excellent results, but because it is technically difficult should be used only by experienced shoulder arthroscopists with thorough knowledge of pathological shoulder anatomy.
