Abstract

A modular prosthesis (10) has an intramedullary rod element (11) which is to be inserted in a bone. The rod (11) has a shaped proximal portion which is telescoped into one end of a bore (30) in the trochanter element. The mating surfaces of the shaped rod (11) and the trochanter bore (30) form a rotationally immovable connection. A neck element (40) is telescoped into the other end of the trochanter bore (30) permitting rotational adjustment. All the elements are locked together by a bolt (50) through the neck and rod (11).
