Results Following Fresh-frozen Humeral Head Osteochondral Allograft Reconstruction for Reverse Hill-Sachs Lesion

Locked posterior glenohumeral dislocations with a reverse Hill-Sachs impaction fracture involving less than 30% of the humeral head are most frequently treated with lesser tuberosity transfer into the defect, whereas those involving more than 50% undergo humeral head arthroplasty. Reconstruction of the defect with segmental femoral osteochondral allografts has been proposed to treat patients between these two ranges, but the medium-/long-term outcomes of this joint-preserving procedure are controversial.

Twelve patients with a unilateral locked posterior shoulder dislocation and at least 30% (mean 31%) impaction of the humeral head were treated with segmental reconstruction of the defect with fresh-frozen humeral head osteochondral allografts. Patients were assessed clinically, radiographically and with computed tomography (CT) at a medium follow-up of 66 months (range, 24-225).All twelve shoulders presented a slight limitation in anterior elevation

Inclusion Criteria:

- Diagnosis of an acute non-reducible posterior gleno-humeral dislocation with an associated McLaughlin lesion affecting more than 30% of the cartilaginous circumference of the humeral head.

Exclusion Criteria:

- Patients with associated injuries to the affected upper limb, with neuromuscular or psychomotor disorders or with disorders affecting connective tissues.
