A prosthesis for partial replacement of a long bone in humans or animals, the prosthesis including: a proximal or distal end component forming one component of a prosthetic joint; a shaft on or assembled with the distal or proximal end component in use; a stem for engagement in a resected bone; and an initially separate collar assembled to the shaft or an extension thereof in use, the collar being dimensioned to abut the resected end face of the bone into which the prosthesis is to be fitted, wherein the end face of the collar facing the resected face of the bone is sized and shaped to correspond to the resected end face of the bone.

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 or condylar head, forming one component of a prosthetic joint, a shaft for assembly with the distal or proximal end component and a stem for engagement in a resected bone. The system allows the assembly of a custom fitted prosthesis from a limited range of components.

Prosthesis for long bone replacement in humans and animals

A surgical distraction device is provided for applying extending or tensioning force non-invasively to a patient's skeleton or to an implant which comprises anchoring means for attaching first and second components of the device to a bone or to adjoining bones, said components being connected by a linkage of an extendible length, a magnet connected to the linkage via a reduction gearbox and actuating means located externally of the patient for generating a moving or varying electro-magnetic field, thereby causing the magnet to rotate and the linkage to be extended.
