Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Allo Omero 2020

Humeral allograft group 12 patients were surgically treated for a locked posterior glenohumeral dislocation with a humeral head defect affecting at least 30% of the head diameter. During surgery, the bone defect was substituted with a fresh-frozen humeral head osteochondral allograft.Included patients were clinically and radiographically re-evaluated for the purpose of this study by examiners not involved in the primary treatment at a mean of 66 months postoperatively. The clinical examination consisted of a physical examination and structured interview. Computed tomography (CT) was carried out at the medium follow-up of 66 months in all patients to evaluate OA progression and allograft resorption.

Intervention Type PROCEDURE

Between 2001 and 2018, a total of 12 consecutive patients were surgically treated for a locked posterior glenohumeral dislocation with a humeral head defect affecting at least 30% of the head diameter. During surgery, the bone defect was substituted with a fresh-frozen humeral head osteochondral allograft.
