Abstract
A novel bone prosthesis for use in healing a bone fracture is disclosed comprising a strong, rigid non-absorbable structural member and a biologically absorbable element held in use under compression against the structural member. Use of the novel prosthesis combines an excellent initial stabilization of the fixed fracture with a gradual shifting of stress-bearing from the prosthesis to the bone in the fracture region as the fracture heals. Thus, problems associated with stress-shielding during healing are alleviated. The structural member may be, e.g., a bone plate, intramedullary rod or hip nail.
