The lateral approach dissects smaller muscles than the posterior approach, but has similar navigation concerns as the anterior approach. Surgeon experience tends to determine the surgeon's preference, meaning that the surgeon will only rarely deviate from what method they were initially trained to use.
The posterior (Moore or Southern) approach accesses the joint and capsule through the back, taking piriformis muscle and the short external rotators of the femur. This approach gives excellent access to the acetabulum and femur and preserves the hip abductors and thus minimizes the risk of abductor dysfunction post operatively. It has the ...
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]
(The more usual left lateral Sims position, suitable for a right-handed practitioner, has the patient lying on their left side.) Posterior view of Sims' position Anterior view of Sims' position The Sims position , or left lateral Sims position, named after the gynaecologist J. Marion Sims , is usually used for rectal examination , treatments ...
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. Anterolateral approach, here shown as a transverse image. The needle will rest on the femoral head (arrow).
It originates on the lateral border of the ischial tuberosity of the ischium of the pelvis. [1] From there, it passes laterally to its insertion on the posterior side of the head of the femur: the quadrate tubercle on the intertrochanteric crest and along the quadrate line, the vertical line which runs downward to bisect the lesser trochanter on the medial side of the femur.
It attaches to the posterior surface of the acetabular rim and acetabular labrum, and extends around the circumference of the joint to insert on the anterior aspect of the femur. [2] The ischiofemoral ligament limits the internal rotation and adduction of the hip when it is in a flexed position.
It is directed lateral and medially and slightly posterior. In the adult it is about 2–4 cm lower than the femoral head. [1] Because the pelvic outlet in the female is larger than in the male, there is a greater distance between the greater trochanters in the female. It has two surfaces and four borders. It is a traction epiphysis. [2]
