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.

A bone prosthesis for use in healing a bone fracture comprising a strong, rigid, biologically non-absorbable structural member, distinct means to secure said structural member to said bone, and a biologically absorbable element adapted to be held under compression between said securing means and said structural member when said prosthesis is secured to said bone, so that stress is transmitted from said bone through said element to said structural member, whereby the stress transmitted to said prosthesis gradually decreases with time during the healing of said bone as said element is absorbed.
