Allograft-Prosthesis-Composite

Allograft prosthetic composite reconstruction (APC)

• APC reconstruction involves combining prosthesis and massive bone allograft or tumor graft.
• The allograft provides a source of bone stock and a site for tendon insertions, while the prosthesis provides a reliable and stable articulation and some support for the allograft, which improves the functional capability.
• An appropriate allograft is selected and the articular surface is removed and substituted with modular prosthesis.
• The allograft is then fixed to host bone with plate and screws.
• Major advantages in children and young adults are the good to excellent function and bone stock available for future revision surgeries or complications.
