Computer-assisted navigation of the hip joint

Hip resurfacing has a place as a bone conserving alternative to THA in the young and active adult with degenerative hip disease. The larger head diameters offer greater postoperative stability and may decrease wear rates. However, hip resurfacing is inherently more difficult to perform than traditional THA because of the limited femoral resection, which makes acetabular visualisation more difficult. Preparing the acetabulum prior to addressing the femoral head creates limitations in terms of exposure and mobilisation of tissues, thus posing a technical challenge to the surgeon and increasing the risk of component malalignment.

Over 100,000 people had hip replacement surgery in the UK in 2016 (National Joint Registry 2017) and more than 300,000 hip arthroplasties are performed annually in the USA. There are two main types of total hip replacement surgery: total hip replacement (THR) and total hip resurfacing arthroplasty (THRA), but in both types a number of different constructional solutions are used.
