摘要：

An orthopaedic implant for use in performing joint arthroplasty is provided. The orthopaedic implant includes a joint component having a stem element defining a external periphery of the stem element. The external periphery of the stem element has a stem resection ring that may be aligned with the resected plane of the long bone. The joint component also includes a body element, which is capable of being fixedly fitted to the stem element and having an external periphery with a body resection ring alignable with the resected plane of the long bone. The external periphery of a canal portion of the body element is spaced inwardly from the external periphery of the stem element so that the body element may be removed from the long bone without disturbing the fixation of the stem element to the long bone.
