Personalised surgical planning for total hip replacement
Research Group Activity
Centre for Imaging, Metrology and Additive Technologies (CIMAT) provides a hub for innovation and research that, for the first time, brings together state of the art technologies for the enhancement and understanding of product and process performance and solve real life problem in multidisciplinary areas encompassing manufacturing, automobiles, forensics, biomechanics and biomedical applications.
Dr Arnab Palit is based in CiMAT and he is interested in joint biomechanics modelling, motion analysis and development of intervention planning tool.
Project Description
Prosthetic and bony impingement are critical post-surgical conditions of total hip arthroplasty (THA). These two conditions arise due to the undesirable relative motion of the hip joint implants, which depend largely on the component positions, bone morphology, and the activities of daily living (ADLs) of the patients. Prosthetic impingement (PI) occurs when the prosthetic femoral neck comes in contact with the rim of the liner/cup. Bony impingement occurs between (a) the femur and the pelvis, (b) when the implanted stem comes in contact with pelvis, or (c) when the bony femur comes into contact with the implanted cup/liner. The risk of these impingements, and consequently, recurrent dislocations is related to a number of factors, such as implant design, their positioning within the native bone geometry, related surgical procedures, bony structures around the hip and other patient related aspects. As a result, pre-operative surgical planning using computer simulation is now regarded as standard practice before THA to identify the best feasible implant positions to avoid post-THA Prosthetic and bony impingement. However, all of these pre-surgical planning are deterministic in nature. They don't consider the variation in inputs, and how these variations lead to uncertainty in the planned output. Therefore, in this project, we will develop a stochastic modelling of hip joint surgical planning considering the variation in various inputs, and investigate the their significance in decision making.
Required Skills
The ability to use MATLAB, specifically to run simulations on data sets, would be desirable.
