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]
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.
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
Femoral nerve dysfunction. Femoral nerve dysfunction, also known as femoral neuropathy, is a rare type of peripheral nervous system disorder that arises from damage to nerves, specifically the femoral nerve. [1] Given the location of the femoral nerve, indications of dysfunction are centered around the lack of mobility and sensation in lower ...
This nerve supplies feeling to the upper, outer thigh. Other nerves that may be affected are the sciatic (leading to a weakness lifting the foot – 'foot-drop'), femoral (weak thigh muscles), obturator (numbness in the inner thigh and weakness of those muscles), and pudendal nerves. The pudendal nerves supply feeling to the reproductive organs.
Lesser trochanter. Left hip-joint, opened by removing the floor of the acetabulum from within the pelvis. Upper extremity of right femur viewed from behind and above. In human anatomy, the lesser trochanter is a conical, posteromedial, bony projection from the shaft of the femur. It serves as the principal insertion site of the iliopsoas muscle.
Anatomical terms of muscle. [edit on Wikidata] The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint. It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus. [1]
The gluteal sulcus (also known as the gluteal fold, tuck, fold of the buttock,, horizontal gluteal crease, or gluteal furrow) is an area of the body of humans and anthropoid apes, described by a horizontal crease formed by the inferior aspect of the buttocks and the posterior upper thigh. [1] The gluteal sulcus is formed by the posterior ...
