The bony pelvis is formed by 4 bones; a pair of hip bones, the sacrum and the coccyx. The bony pelvis supports the pelvic viscera and works to transmit force from the axial skeleton to the lower limbs.
The two hip bones are related anteriorly by the symphysis pubis and posteriorly to the sacroiliac joints bilaterally.
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
