Improved implant-bone fit appears to increase the longevity of cementless total joints. This article describes design software that uses 3D bone models generated from X-ray computerized tomography to produce optimal-fit hip stems for individual femurs. The result is an implant designed to optimize load transfer and minimize stem motion within a given bone.
