Savilonis, Brian James
The group designed a non-invasive strain application device that improved upon existing fracture healing devices such as external fixators, casts, and functional braces. The design included combining an AirCast walking boot and patellar tendon bearing (PTB) brace, with the ability to create a gap beneath the heel. Three tests were used to verify the mechanical properties of the analogue bones, the strains at the fracture site produced by various forces, and the forces experienced at different locations on the foot while wearing the device. Through proof of concept, the testing showed that introducing a gap in the device correlates to a dampened force and strain at the fracture site for optimal healing conditions.
