Biomechanical study of a highly stable intramedullar osteosynthetic device.
A biomechanical study of a very stable and reliable system for long bone consolidation is presented. The osteosynthetic devices composed of a strong intramedullary nail, fixed by bolts to the compact bone, offers the possibility of immediate full weight bearing of the injured limb, even in cases of comminuted fractures, with osseous loss. Mechanical characteristics of the 'nail-bolt-bone system' are shown, particularly stability and elasticity. In spite of the rigidity of the nail, elastic movements and compression Of bone segments, facilitating the union process, have been measured.
