Many muscles contribute to these movements: The psoas is the primary hip flexor, assisted by the iliacus. The pectineus, the adductors longus, brevis, and magnus, as well as the tensor fasciae latae are also involved in flexion. The gluteus maximus is the main hip extensor, but the inferior portion of the adductor magnus also plays a role.
Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries.
In vertebrate anatomy, the hip, or coxa (pl.: coxae) in medical terminology, refers to either an anatomical region or a joint on the outer (lateral) side of the pelvis.. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and lateral to the obturator foramen, with muscle tendons and soft tissues overlying the greater trochanter of the femur.
The quadratus femoris is a flat, quadrilateral skeletal muscle. Located on the posterior side of the hip joint, it is a strong external rotator and adductor of the thigh, [2] but also acts to stabilize the femoral head in the acetabulum. The quadratus femoris is used in Meyer's muscle pedicle grafting to prevent avascular necrosis of femur head.
The hip bone ( os coxae, innominate bone, pelvic bone [1] or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis . The two hip bones join at the pubic symphysis and together with the sacrum ...
The human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton ...
The femoral head's surface is smooth. It is coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the femoral head, and gives attachment to the ligament of head of femur . The thickest region of the articular cartilage is at the centre of the ...
Tenotomy. An adductor tenotomy (cutting the origin tendons of the adductor muscles of the thigh) and obturator neurectomy (cutting the anterior branch of the obturator nerve) are sometimes performed on children with cerebral palsy. These children often have hypertonia of the adductor muscles, making abduction difficult, obstructing normal hip ...
