"articulation: ball and socket joint between the head of the femur and the acetabulum"
"ligaments: ischiofemoral, iliofemoral, pubofemoral and transverse acetabular ligaments, and the ligamentum teres 1"
"movements: thigh flexion and extension, adduction and abduction, internal and external rotation"
"blood supply: branches of the medial and lateral circumflex femoral, superior and inferior gluteal arteries and obturator arteries 2"
"innervation: femoral, obturator and superior gluteal nerves, and nerve to quadratus femoris 2"

"The acetabulum is formed by the three bones of the pelvis (the ischium, ilium and pubis). Between them is a Y-shaped cartilaginous growth plate (the triradiate cartilage) which is usually fused by age 14-16. The ball and socket articulation allows for a high degree of mobility. The acetabular labrum increases the depth of the joint 1, thereby increasing the stability of the joint but causes a reduction in the movement at the joint. In comparison to the shoulder joint, it permits less range of movement due to the increased depth and contact area but displays far more stability."
"Thickenings of this capsule constitute the ischiofemoral, iliofemoral and pubofemoral ligaments:"
"Subtendinous, iliopectineal and greater trochanteric bursae, and bursae between gluteus maximus and vastus lateralis exist near the joint 1."
"The joint is surrounded by a fibrous capsule, which is attached to the margins of the labrum and the transverse ligament on the acetabulum. It extends to the femur to attach anteriorly to the intertrochanteric line but as not as extensive posteriorly, attached halfway to the intertrochanteric crest. There are circular (internal) and longitudinal (external) fibres. The zona orbicularis is a set of internal circular fibres forming a collar around the femoral neck and partly blended with pubofemoral and ischiofemoral ligaments"
"There are a number of different muscles that permit flexion/extension, adduction/abduction, and internal/external rotation of the hip joint. See: Hip muscles."
