Abstract:
1. A multi-piece prosthetic joint component, comprising: an elongate, longitudinally oriented outer sleeve including an outer sleeve surface adapted for contact with native bone and defining a radially oriented proximal sleeve border, a radially oriented proximal sleeve rim intersecting the outer sleeve surface at the proximal sleeve border, an outer sleeve body enclosed by the outer sleeve surface and the proximal sleeve rim, and an elongate, longitudinally oriented stem-receiving cavity formed in the outer sleeve body and intersecting the proximal sleeve rim to define a stem-receiving aperture; and a joint articulating member including an elongate, longitudinally oriented stem, an articulating surface, and an interface rim, the stem being longitudinally spaced from the articulating surface and configured for selective insertion into the stem-receiving cavity, and the interface rim being located on the joint articulating member intermediate the stem and the articulating surface; wherein when the stem is at least partially inserted into the stem-receiving cavity, the proximal sleeve rim and the interface rim interact to change a longitudinal relationship between the outer sleeve and the joint articulating member responsive to relative radially-oriented rotation between the stem and the stem-receiving cavity.
