Web2 days ago · Introduction: In total hip arthroplasty (THA), the correct position of the acetabular component directly determines the outcome of the surgery, or the success of the surgery. Therefore, how to accurately locate the position of the acetabular component has become a very critical step in THA.
WebStem alignment was defined as the angle between the long axis of the prosthetic stem and the anatomical axis of the femur. The canal filling ratio on the AP radiograph was calculated by dividing the width of the stem by the inner cortical width at a point 5 cm distal to the lesser trochanter. WebTotal hip arthroplasty (THA) is a well-established and effective surgical treatment for hip arthritis and is generally associated with positive outcomes relating to stability, durability, range of motion, and rehabilitation. 1 However, THA has also been associated with adverse outcomes, potentially leading to revision surgery if conservative …
