Abstract
Disclosed is an improved universal modular prosthetic stem extension which may be installed on a prosthesis in a multiplicity of differing orientations to allow adaptation to a multiplicity of differing patient conditions. The stem includes a coupling mechanism allowing the stem to be rotated to any one of a multiplicity of rotative positions with respect to a prosthetic base, whereupon the stem may be tightened and fixed in position at a desired such orientation. The inventive stem extension is disclosed in conjunction with embodiments of distal femoral, proximal tibial, and proximal femoral prostheses.
