Abstract:

Total hip arthroplasty (THA) is an orthopaedic surgery to replace the diseased femoral head and socket of the hip joint with artificial implants. Achieving appropriate leg length and offset in THA is critical to avoid instability, leg length discrepancies, persistent pain, or early implant failure. This paper provides an electromagnetic (EM) sensor based approach for accurately measuring the change in leg length and offset intraoperatively. The proposed approach does not require direct line-of-sight, avoids the need for accurately returning the leg back to the neutral reference position, and has an efficient closed-form solution from least squares optimisation. Validations using simulations, phantom experiments, and cadaver tests demonstrate that the proposed method can provide more accurate results than the conventional method by manual gauge, the standard optical tracking based approach, and the direct use of one EM reading, thus showing significant potential clinical value.
