The implant (100) comprises a body (102) having at least one end (104). The body (102) is elongate as it is arranged to substantially mimic a portion of a skeletal bone. The embodiment of the implant (100) is designed to be implanted in the leg of a patient, as a partial replacement for the femur bone of a patient. The at least one end (104) which includes a stepped portion (106) is arranged to, in use, prevent migration of the implant into the bone of a patient. At least part of the stepped portion (106) is covered by a physiologically inert substance, such as niobium for example, to reduce the possibility of infection or an immune reaction at the site at which the implant (100) contacts the flesh of the patients leg.
