Abstract: A stem component having a body portion and a connection portion is provided. A portion of the stem component may be fitted to a cavity in a canal of a long bone. The stem component includes a canal portion and a sleeve portion that has an internal periphery that forms an internal cavity. A portion of the external periphery of the sleeve portion may be fitted to the cavity of the long bone. A portion of the external periphery of the connection portion may be fitted into the internal cavity of the sleeve portion, so that the external periphery of the connection portion of the joint component is spaced inwardly from the external periphery of the sleeve portion of the stem component when the joint component is fixedly connected to the stem component so that the joint component may be removed without disturbing the fixation to the long bone.

Abstract: 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.

Abstract: A kit for use in performing revision surgery on a cavity in a canal of extending from a resected plane a long bone is provided. The kit includes a canal component fitted to the cavity. The canal component includes a canal portion having first and second ends. The canal component further includes a sleeve portion having an external periphery and an internal periphery defining an internal cavity. The kit also includes a first joint component having a body portion and a connection portion. The connection portion is fitted into the sleeve portion. A connection portion of a second joint component also may be fitted into the sleeve portion so that the external periphery of the connection portion of the first joint component is spaced inwardly from the external periphery of the sleeve portion of the canal component when the first joint component is fixedly connected to the canal.
