Abstract
A modular prosthesis has an intramedullary rod element which is to be inserted in a bone, an artificial trochanter and a neck for carrying the ball. The intramedullary rod has a proximal end and a distal end telescoped together allowing free relative rotation of the ends. A split sleeve is fitted between the telescoped portions of the rod to form a rigid connection when the ends are separated longitudinally. A jack screw within the intramedullary rod separates the proximal end from the distal end.
