Long - Term Outcome of Segmental Reconstruction of the Humeral Head for the Treatment of Locked Posterior Dislocation of the Shoulder

Abstract

Locked, posterior, glenohumeral dislocations with impaction fractures involving less than 30 to 35% of the humeral head are most frequently treated with lesser tuberosity transfer into the defect, those involving more than 35-40% with humeral head arthroplasty (HA). As an alternative, reconstruction of the defect with segmental femoral or humeral head allograft has been proposed, but long-term outcome of this joint preserving procedure is unknown.
