Abstract
An intramedullary prosthesis, particularly but not exclusively a hip prosthesis, is provided comprising an articulating member at one end and a stem at the other. The stem is shaped to conform substantially to the transverse sections of the medullary canal into which it is to be inserted, and is preferably covered with a porous resilient coating which is oversized with respect to the stem socket prepared in the medullary canal. The coating becomes compressed as the stem is inserted into the canal. The porous resilient layer also promotes the ingrowth of tissue thereby ensuring the long term fixation of the prosthesis.
