Abstract
The feasibility of using guided ultrasonic waves to monitor osseointegration in intraosseous transcutaneous amputation prosthesis (ITAP) implants during rehabilitation was explored. Osseointegration, where bone grows onto orthopaedic implants, is critical for implant stability and long-term clinical success. Experiments used a synthetic bone model in which osseointegration was simulated by the increasing stiffness of slow curing epoxy in the bone-implant interface. Guided wave signals (longitudinal modes) were excited and recorded at the distal end of the implant, showing significant change of wave pulse arrival time and amplitude during the process. Results were compared to finite element simulations to predict the choice of guided wave modes and relate guided wave signal changes to interface stiffness changes due to bone healing during the rehabilitation process.
