Arthroscopic Management of Anterior Instability in Patients With Moderate Humeral Bone Loss
Bone loss is a known associated finding in anterior shoulder instability, but only recently has the role of bone loss in failed arthroscopic stabilization of the shoulder been recognized. In a classic study of glenohumeral bone defects after arthroscopic Bankart repair, the rate of recurrent instability was found to be 10 times greater in patients with bone loss than in patients with no bone loss. The rate of recurrent instability after arthroscopic stabilization in the presence of bone loss was even higher in contact athletes (89%). More recently, a recurrence rate of 75% was noted after arthroscopic Bankart repair in patients with capsular laxity and bone loss greater than 25%. The authors of that study developed an algorithm to estimate the risk of failure after arthroscopic stabilization. Bone loss alone resulted in a 50% failure rate, and when bone loss was combined with young age or participation in competitive contact sports, the rate of failure increased to 75%.
