The hip joint is a large synovial socket and ball joint which is formed by the femoral head (the ball) and the acetabulum (the socket). The acetabulum is formed by pelvic bones; the ilium, the ischium and the pubis.
The hip joint represents the articulation between the lower extremity and the axial skeleton and allows a high degree of mobility while being stable.
The muscles of the hip consist of four main groups
Gluteal group: the gluteus maximus, gluteus medius, gluteus minimus and tensor fasciae latae
Adductor group: the adductor brevis, adductor longus, adductor magnus, pectineus and gracilis
Iliopsoas group: the iliacus and psoas major
Lateral rotator group: the externus and internus obturators, the piriformis, the superior and inferior gemelli and the quadratus femoris
Other hip muscles: the rectus femoris and the sartorius
