Abstract:

Disclosed is a tapered femoral hip stem implant for use in total hip replacement surgery. The implant is constructed using anthropomorphic data to obtain an optimal configuration for use in hip replacement surgery as well as to promote bone regrowth in the anterior proximal dimensions. In certain aspects, the implant is particularly well suited for use in an anterior approach to total hip replacement surgery due to its relatively small stem length. The implant includes a 12 degree proximal taper, which affords inherent fixation and rotational stability and a 4 degree distal taper to reduce the possibility of stress shielding.
