ABSTRACT:
A surgical method of measuring bone strain to detect fracture consolidation includes the steps of affixing an external fixation device to the patient's bone that has a fracture site to be healed and wherein the fixation device supports an elongated optical fiber. Light is transmitted through the optical fiber to an exit point. The light intensity within the optical fiber is measured, preferably at the exit point as the light travels through the optical fiber. Light intensity is measured to monitor strain in the fixation device as the fracture site heals. A physician then determines when the site has fully healed by observing changes in light intensity as the patient's bone rather than the fixation device carries more of the patient's normal body loading.
