title: Double Hill-Sachs lesion: a report of two cases.
abstract: Hill-Sachs lesions are common after anterior dislocation of the shoulder. We present two cases of uncommon double Hill-Sachs lesions composed of a typical Hill-Sachs lesion and an atypical extra compression fracture with a rim of normal cartilage in between. Both patients had two anterior shoulder dislocations before surgery. These case reports show that recurrent posttraumatic anterior glenohumeral dislocations can result in increased damage to the humeral cartilage.
