Abstract

A telemetric biofeedback concept for continuous monitoring of bone healing is introduced. The system is based on an implantable electronic unit with on-board data processing of deformations or displacements of fracture fixation devices. In contrast to existing solutions, it allows for autonomous long-term data collection over several months. The system enables observing fracture motion and patient activity under daily routine conditions. Feasibility of the approach was proven in an animal experiment with an instrumented plate monitoring axial motion in a transverse osteotomy gap at the sheep tibia. Callus formation and maturation of the repair tissue was indicated by a decline of the interfragmentary motion signal over time and by changes in the animal's activity pattern. For improved understanding and interpretation of such information, extended collection of in-vivo data is the consequent next step.
