Abstract

Quantitative computed tomography (CT) methods are used to reconstruct the cross-sectional anatomy of individual femurs. Automatic contour detection algorithms and interactive editing are used to transform this data into 3-D models of the medullary canals. Each model is then used as input for a computerized implant design program whose output is a customized, exact-fit femoral intramedullary implant. It is hypothesized that a closer fitting implant will have better stress distribution to the bone, and therefore, greater longevity.
