Abstract

A conceptual model that relates the phenomenological stimuli responsible for bone remodeling has been developed as a preliminary exercise in a study designed to quantify Wolff's Law. In this regard, a set of thermodynamic and chemical kinetic equations have been formulated and their use in describing and predicting the formulation of crystalline hydroxypatite is presented.

As a parallel activity, a macrocopic structural analysis of the bone‐pylon interface has been conducted using a finite element representation and the results of this investigation are discussed as they relate to establishing a set of pylon design criteria.

Finally, a modular, endoskeletal prosthetic system is described. The design of this appliance is based on the concept of total cosmesis and provides the present amputee with increased comfort and functionality as well as providing a system that can be effectively interfaced with a bone pylon when direct skeletal attachment (DSA) becomes a clinically accepted procedure.
