Introduction Total hip arthroplasty (total hip replacement) is an orthopedic procedure that involves the surgical removal of the head and proximal neck of the femur and removal of the acetabular cartilage and subchondral bone – the damaged bone and cartilage is removed and replaced with prosthetic components. For successful results, the total hip arthroplasty components must be secured firmly to the bone, either with polymethylmethacrylate cement or, in more recent uncemented designs, by bony ingrowth into a porous coating on the implant, resulting in "biologic" fixation. Total hip arthroplasty was first introduced in the United States in 1969 and is currently one of the most widely performed procedures in orthopedic practice and has been shown to be successful in eliminating pain and restoring function in hips with diseases such as osteoarthritis (Siopack & Jergesen, 1995).
There are two types of

The measurements measured the activity and pure joint motion of healthy individuals compared to previous studies. Secondly, a CT dynamic simulation which can identify range of motion restriction due to osseous impingement. The data allowed Turley, Williams, Willings & Griffin (2013) the ability to distinguish between which mode of restriction was limiting range of motion for a given maneuver. The results show that motion in pure flexion and flexion combined with adduction are at risk of osseous impingement – indicating a motion where the maximum likely damage will occur in the FAI or are at risk of prosthetic impingement post-THA. Also, motions in extension and adduction combined with flexion are limited by soft tissue restraint, while motions such as pure abduction are at risk for soft tissue impingement (Turley, Williams, Willings & Griffin,
