A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely.
Two common anterior approaches are typically used both with the patient lying supine: The anterior longitudinal approach: the probe is aligned along the long axis of the femoral neck. The needle is introduced from an anteroinferior approach and is passed into the anterior joint recess at the femoral head-neck junction.
Minimally invasive techniques for total hip arthroplasty (THA, or hip replacement) have been well described by various authors including: Richard Berger: "2 incision" technique + fluoroscopy. Thomas P.Sculco: posterior approach. Innsbruck (Prof.Nolger): Direct anterior.
[medical citation needed] For example, a hip joint that is affected by osteoarthritis may be replaced entirely (total hip arthroplasty) with a prosthetic hip. This would involve replacing both the acetabulum (hip socket) and the head and neck of the femur. The purpose of this procedure is to relieve pain, to restore range of motion and to ...
The anterior approach accesses the hip joint from the front, with less large muscle dissection but due to the proximity of the femoral artery, corresponding vein, and main nerve bundle for the leg lying just medial to the acetabulum the surgeon must exercise caution and maintain suitable landmarks.
Hip arthroscopy refers to the viewing of the interior of the acetabulofemoral (hip) joint through an arthroscope and the treatment of hip pathology through a minimally invasive approach. This technique is sometimes used to help in the treatment of various joint disorders and has gained popularity because of the small incisions used and shorter ...
