ABSTRACT:
A bone joint endoprosthesis is formed of a proximal member and a distal member. The former is a semi-cylindrical profiled body having a proximal flat chordal surface and a semi-circular T-slot concentric with the joint axis opening distally. The latter comprises an intramedullary stem and a proximal arcuate segment of I-shape cross-section whose free end is slidably carried in the T-slot. The unit allows for normal flexion and extension motion and joint stability is provided by the T-slot arrangement of the joint articulation.
