Open Capsular Repair without Bone Block for Recurrent Anterior Shoulder Instability in Patients with and without Bony Defects of the Glenoid and/or Humeral Head

BackgroundBony defects of the humeral head and glenoid have been associated with high failure rates after arthroscopic stabilization for anterior instability. Biomechanical studies have indicated that such lesions reduce stability and may predispose to failure and motion loss after capsular repair.PurposeThe present investigation was designed to evaluate the effect of bony deficiency of the glenoid and/or humeral head on recurrence rates with a conventional open technique of anterior stabilization without a bone block.Study DesignCase series; Level of evidence, 4.Materials and MethodsOne hundred nineteen consecutive patients with recurrent anterior shoulder instability were treated by a single surgeon with an open anterior stabilization procedure. Patients were studied prospectively for recurrent instability after the presence and size of bony defects of the humeral head and/or glenoid were recorded during an arthroscopic examination before the open procedure. One hundred three patients (mean age, 20.7 ye...
