Abstract
The present invention relates to a universal modular prosthesis stem extension designed to be attachable on the undersurface of a femoral or tibial standard prosthesis. The stem extension forms a part of a modular system wherein a single stem extension could be selectively attached to any one of a multiplicity of femoral or tibial components, thus reducing the amount of inventory which is necessary to be maintained by a surgeon. In the preferred embodiment of the inventive stem extension, each stem extension is designed with a 6 degree valgus inclination and is reversible for left and right patients.
