Table 3 Technical differences of the currently reported technique from that of osteo-chondral allograft

From: Chronic locked posterior gleno-humeral dislocation: technical note on fibular grafting for restoration of humeral head sphericity

Technical difference

Current technique

Osteo-chondral allograft

Approach

Open

Open

Measurement of defect size

Essential

Reconstructive graft

Autologous fibula

Osteo-chondral allograft (humeral head, femoral head, talus)

Graft availability

Readily available

Necessity of tissue banking systems

Graft preparation and fashioning

Simplified

Technically demanding

Graft bone marrow elements

Washed out by copious lavage

Fixation method

4 mm Cancellous screws

Press-fit

Countersunk screws/pins

Enhancement of local biology

Microfracture

Platelet-rich plasma

Concurrent posterior GH capsulorrhaphy and McLaughlin’s procedures

Feasible

Feasible

Reconstructed articular surface

Lateral surface of native fibula + Fibrocartilage

Articular cartilage
