IMProVA - Intra-operative Monitoring of Acetabular Prosthesis Fixation using Vibration Analysis

Total Hip Arthroplasty (THA) is a surgical procedure during which a damaged hip joint is replaced by an artificial joint. During cementless THA, the acetabular implant is press-fitted into the bone by means of hammer blows. The quality of this initial fixation is a vital factor for a long lifetime of the implant. However, finding the hammering endpoint that corresponds to a proper initial fixation is currently based on the subjective experiences of the surgeon, which can be challenging and may lead to improper fixation resulting into early failure of the implant. Therefore, the project’s ambition is to tackle this challenge by offering the surgeon real-time objective information on the implant fixation. A vibration analysis based approach with an add-on instrumentto monitor the acetabular implant fixation will be implemented. Based on a solid proof-of-concept and using the experience of recently finalized clinical experiments, this project aims to deliver a packaged smart medical instrument that is ready for clinical validation studies.
