Bone deformation recorded in vivo from strain gauges attached to the human tibial shaft.

摘要: It is generally accepted'that mechanical circumstances can profoundly influence the course of growth, remodelling and repair in bone. How this exerts its.elf obscure unlikely to be clarified until more known involved. A knowledge these also becomes increasingly important as greater emphasis placed on internal fixation prosthetic replacement skeletal components. Instrumentation a bone's surface with strain gauges has made it possible record bone deformation during various activities animals (Lanyon & Smith 1970, Lanyon 1973, 1974). Such data are limited significance being relevant only small area surface. However method one at present available which produced direct information how responds normal loading. The value such some extent determined by whether generalisations concerning response species applicable others, particular man. In an attempt determine relevance animal man was decided instrument part human skeleton using techniques previously employed experimental animals. antero-medial aspect tibial midshaft chosen for its surgical accessibility.
