Abstract
The specification discloses a modular system for the formation of a prosthesis for the replacement of a long bone in a human or animal body. The system provides a prosthesis comprising a proximal or distal end component such as a trochanter (1) or condylar head, forming one component of a prosthetic joint, a shaft (5) for assembly with the distal or proximal end component and a stem (8) for engagement in a resected bone. The system allows the assembly of a custom fitted prosthesis from a limited range of components.
Claims6
A prosthesis for partial or total replacement of a long bone in humans or animals, said prosthesis comprising a proximal or distal end component forming one component of a prosthetic joint, a shaft assembled with the distal or proximal end and a stem for engagement in a resected bone, the shaft, stem and the distal or proximal end components being connected by male and female tapers, each male taper including a projection which extends longitudinally of the prosthesis but is offset from its axis and engages in a corresponding recess in the female taper, a cross-hole being provided for access transversely to the region of the end of the male taper by a disassembly tool, and wherein said projection maintains adjacent components in the desired angular relationship.
