The most prominent fracture to the distal radius is a Colles fracture. 5-10% of Colles fractures experience non-unions, healing defects that hinder healing by preventing the two ends of the fracture from joining to form a callus. Currently, the only way to assess healing is qualitatively through imaging. There is no way to quantify the extent of bone healing. A proof of concept screw-driven device was created that applied a non-damaging bending load to a healing distal radius fracture. However, the device lacked an efficient force application or data retrieval system.The goal of this project was to redesign the force application system to improve ease of use, force application efficiency, and create a digital output to record the force being applied to a patient's wrist in real time.
