Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. [1] Hip replacement surgery can be performed as a total replacement or a hemi/semi(half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures.
An anterior-posterior (AP) X-ray of the pelvis and a cross-table lateral X-ray [24] of the effected hip are ordered for diagnosis. [4] [5] [16] The size of the head of the femur is then compared across both sides of the pelvis. The affected femoral head will appear larger if the dislocation is anterior, and smaller if posterior. [7]
Hip replacement surgery can be performed from three main directions, each with advantages and disadvantages The classical approach is the posterior, and requires dissection of the gluteus maximus and other large muscles of the back of the thigh to access the acetabulum.
The modified posterior MIS approach to hip resurfacing and total hip arthroplasty (hip replacement) displays a host of advantages to the patient: Less post-operative pain; Less soft tissue damage and pressure on muscle fibres. Shorter hospital stay; Lower blood loss; Smaller incision; Quicker return to work and functional activities [2]
(Cerezal)" This orientation might be favorable for the tensed fibers of the ligamentum teres. The fovea capitis is located "slightly posterior and inferior to the center of the articular surface of the femoral head (Cerezal)" Unlike the head of the femur, the fovea capitis lacks any hyaline cartilage.
The pelvic bone, also known as the innominate bone, is formed by three bones fused together: the ilium, ischium, and pubis. The musculature of the hip is divided into anterior hip muscles and posterior hip muscles. The major nerve supply that runs through the hip joint is the femoral nerve and the sciatic nerve. [16]
