Sound Hip: research on the fixation of the hip prosthesis

During a cementless total hip arthroplasty (THA), the hip prosthesis is press-fit in the femur. This initial fixation of the prosthesis is one of the most important factors to obtain a long term stability and so avoiding an early revision of the prosthesis. Finding the point of optimal implant fixation, currently based on auditory and tactile sensation of the surgeon, is challenging because the margin between obtaining the optimal fixation and an intra-operative fracture is very narrow, especially in revision surgery. The goal of this project to develop a device to assess the intra-operative fixation and the fracture risk of revision THA implants based on vibro-acoustics, by bridging the gap between the existing research and an implementation in the hospital. Therefore, this projects builds further on the results of ongoing projects by optimizing the realized proof of concept, in silico and in vivo, and merging the different elements of the measurement method in a user-friendly device, resulting in a decision support device that is ready to be used in the hospital.
