A surface-based approach to determine key spatial parameters of the acetabulum in a standardized pelvic coordinate system

Total hip arthroplasty (THA) is considered to be a successful treatment for patients with end-stage hip osteoarthritis [1]. Diseases and surgical procedures of the hip are inherently three-dimensional (3D), occurring in and around the proximal femur and the acetabulum. With the advent of cementless implants, the orientation of the femoral component must be consistent with the geometry of the femoral medullary cavity. Correct implantation of the acetabular component in THA is critical with respect to long-term survival as well as short-term complications [2].
