Abstract
A system for monitoring the ossification of an internally fixated fracture in a bone of a subject includes an implantable fixation device and an external wireless reader operative to transmit relative load data experienced by a bone plate across a fracture to a data server where trends in the change in added bone-support provided by the bone plate may be visualized. The implantable fixation device includes a primary load sensor and a reference load sensor, where a load value from the reference load sensor may be used to normalize the load value from the primary load sensor. The external wireless reader is in wireless communication with the implantable fixation device and is operative to receive a signal indicative of the load from each load sensor and to energize each load sensor via inductive charging.
