Claim Text:
1. A prosthetic joint component, comprising: an elongate, longitudinally oriented outer sleeve including an outer sleeve surface configured for implantation into native bone of a patient and having a sleeve body extending between longitudinally separated proximal and distal sleeve ends, a stem-receiving cavity extending from the distal sleeve end into the sleeve body substantially in a first longitudinal direction, the sleeve including a sleeve interference protrusion extending from the distal sleeve end away from the sleeve body substantially in a second longitudinal direction opposite the first longitudinal direction; and a joint articulating member including an elongate, longitudinally oriented stem with longitudinally spaced proximal and distal stem ends separated by a stem body, the proximal stem end being configured for selective insertion into the stem-receiving cavity, the joint articulating member including a joint articulating surface spaced apart from the distal stem end by an angularly extending connector neck; wherein when the stem is inserted into the stem-receiving cavity with the outer sleeve and joint articulating member implanted within the patient's body, the stem and the outer sleeve are configured for selective relative rotation, impelled by action of the patient, about a shared longitudinal axis, and the connector neck impinges upon the sleeve interference protrusion responsive to a predetermined amount of relative rotation between the stem and the outer sleeve to prevent relative rotation between the stem and the outer sleeve outside a predetermined range of allowable rotation.
