Fresh Osteochondral Allograft to the Humeral Head for Treatment of an Engaging Reverse Hill-Sachs Lesion
Posterior dislocation of the shoulder is rare, occurring in approximately 2% to 4% of all shoulder dislocations. Through a mechanism similar to that first characterized by Hill and Sachs, these dislocations have the potential to result in impaction fractures of the anterior aspect of the humeral head. These so-called reverse Hill-Sachs or McLaughlin lesions are estimated to occur in 86% of acut...
متن کاملPosterior Shoulder Instability with a Reverse Hill-Sachs Defect: Repair with Use of Combined Arthroscopic Labral Repair and Fracture Disimpaction: A Case Report.
A cute traumatic posterior glenohumeral dislocations are rare; they are typically caused by high-velocity trauma, epileptic seizures, or electrocution. Anterior impression fractures of the humeral head (reverse Hill-Sachs defect) occur in over 80% of individuals following a posterior dislocation of the shoulder. The size of reverse Hill-Sachs defects varies and has been reported to be as large ...
متن کاملOsteoarticular allograft reconstruction for hill-sachs lesion in an adolescent.
Glenoid and humeral head bone loss is the most common cause of failure after surgical shoulder instability stabilization. Large Hill-Sachs lesions involving >30% of the articular surface of the humeral head typically occur after neglected or locked shoulder dislocations. Such large lesions may require osteochondral allograft reconstruction or prosthetic replacement to regain shoulder stability ...
متن کاملManagement of humeral and glenoid bone loss--associated with glenohumeral instability.
UNLABELLED Anterior glenohumeral instability complicated by bone loss is a challenging problem and, when severe, may require surgical treatment with bone grafting. We review our institution's experience with humeral head and glenoid bone grafting for large Hill-Sachs lesions and glenoid defects. MATERIALS AND METHODS Patients who underwent intra-articular bone reconstruction for Hill-Sachs an...
متن کاملConcomitant 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
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 debilitat...
