Concomitant Reverse Hill-Sachs Lesion and Posterior Humeral Avulsion of the Glenohumeral Ligament: Treatment With Fresh Talus Osteochondral Allograft and Arthroscopic Posterior Humeral Avulsion of the Glenohumeral Ligament and Labrum Repair

چکیده
Chronic posterior glenohumeral joint instability can be a challenging clinical entity for patients and surgeons alike. In the setting of a posterior dislocation, a large anterior humeral impaction injury (reverse Hill-Sachs [HS]) may occur, leading to engagement of the humerus with the posterior glenoid bone, especially during internal rotation of the joint. A reverse HS is especially debilitating because of the significant portion of affected humeral head cartilage, and is made worse in the setting of ligamentous disruption such as a posterior humeral avulsion of the glenohumeral ligament (HAGL) lesions. Although several nonanatomic procedures to address these defects have been previously described, recent interest in anatomic reconstructions capable of restoring the cartilage surface of the humeral head has led to the use of bone grafts (autografts and allografts) to restore the articular contour of the humeral head in conjunction with anatomic repair of associated soft tissue injuries. We present our preferred technique for an anatomic repair of a posterior HAGL lesion in combination with reconstruction of an engaging reverse HS lesion using an unmatched hemitalar allograft.

T he pathoanatomy of anterior shoulder dislocations has been well documented. Perthes described an anterior labral lesion as early as 1906, and Bankart wrote his classic article on recurrent anterior dislocations more than seventy years ago. Until recently, much less had been written about posterior shoulder instability; to our knowledge, the first case series was reported by Reeves in 1963. Re...
متن کاملArthroscopic Repair of Humeral Avulsion of the Glenohumeral Ligament Lesion
Humeral avulsion of the glenohumeral ligament (HAGL) is a lesion associated with anterior shoulder instability. Although uncommon, HAGL lesions are a significant contributor to shoulder pain and dysfunction and, if missed, can even be a cause of failed Bankart repair. HAGL lesions should generally be repaired surgically; however, given their low prevalence, there is no consensus on the optimal ...

The "floating" posterior inferior glenohumeral ligament (floating PIGHL) is an uncommon cause of posterior shoulder instability. This pathologic lesion, defined as detachment of both the origin of the PIGHL (posterior Bankart lesion) and insertion of the of the PIGHL from its humeral head insertion site, often results in significant and persistent shoulder instability symptoms. An effective sur...
