Patent ID: 8562687

Claim:
A disposable modular spacer device of the articulation of a knee comprising a tibial element, adapted to be constrained to an end of the tibial bone in proximity of the articulation of the knee, said tibial element comprising a lower surface and an upper surface provided with a radius of curvature R 2 , and a femoral element, said femoral element comprising an inner surface, adapted to be constrained to an end of the femoral bone at the articulation of the knee, and an outer convex surface, provided with a radius of curvature R 1 and adapted to enter in contact with said upper surface of said tibial element, said tibial element and femoral element each being selected from tibial elements and femoral elements having various dimensions or sizes, wherein each size of said tibial element is interchangeable with each size of said femoral element to adapt the dimensions of said modular spacer device with the dimensions of the bone ends to which it should be connected.
