ABSTRACT:
A passively extensible long bone component in an endoprosthetic bone joint device for a child includes two parts, of which one (10,20) has a bearing portion (22) to serve the articulatory function at one end of the bone, a seat portion (11) to engage the bone one end proximally of the growth plate therein and a stem (21) to pass longitudinally into the bone, and of which the other part (30) is a generally tubular socket adapted to receive the stem in sliding engagement and for securement with the bone distally of the growth plate. The bearing part can be cushioned against shock, at least partially separable, and extend as a further socket between the first socket and the stem. The component can allow rotation of the bearing and stem about the bone long axis or inhibit such rotation.
