Synovial fluid is what allows us to flex our joints under great pressure without wear. The major muscles that produce movements of the hip joint are categorized into functional groups; flexors, extensors, adductors, abductors, lateral rotators and medial rotators. Abduction and adduction of the hip joint occur in the coronal plane and have a free range of movement of about 45o.

It arises from the iliopubic ramus, the superior pubic ramus and the obturator crest of the pubic bone. The hip joint is a ball-and-socket type of synovial joint situated deeply within the pelvis. This structure deepens the acetabulum by raising the rim of the acetabulum slightly, thereby increasing the acetabular articular area by about 10%. The transverse ligament of the acetabulum is a strong flat ligament that bridges the acetabular notch creating the acetabular foramen through which neurovascular structures enter the hip joint. The lunate surface forms an incomplete ring that occupies the superior and lateral aspects of the acetabulum; missing its inferior segment. This action restricts extension of the hip joint beyond the vertical position to between 10o to 20o. The external fibrous layer of the capsule is attached to the acetabulum proximally, close to the margin of the acetabular rim and to the transverse acetabular ligament. The hip is a complicated joint made of bone, cartilage, ligaments, muscle, and a lubricating fluid.

The capsule has two major groups of fibers, longitudinal and circular. Clinically Oriented Anatomy (7th ed.). It forms a connection from the lower limb to the pelvic girdle, and thus is designed for stability and weight-bearing – rather than a large range of movement.. The pubofemoral ligament lies anteroinferiorly and reinforces the anterior and inferior aspects of the joint capsule. The blood supply of the hip joint is from the medial and lateral circumflex femoral arteries (branches of the deep artery of the thigh), the obturator artery and the superior and inferior gluteal arteries. Burtha And Hip Joints Diagram. The following nerves serve the gluteal and thigh regions: Superior clunial nerve (L1–L3): […] Palastanga, N., & Soames, R. (2012). Internal and external rotation of the hip joint occurs in the horizontal plane about the mechanical axis of the femur rather than the long axis of the femoral shaft.

For example, the range of internal rotation with the hip extended is about 35o while external rotation is about 45o. The acetabulum bears a prominent semilunar region known as the lunate surface that is covered by articular cartilage. This ligament is a flattened triangular band of connective tissue that has no significant contribution to the strength and stability of the hip joint. • Don’t roll your knee or toes inwards. It consists of the acetabulum (hip socket) and the femoral head (ball) of the femur. Back Side. In this joint, the head of the femur articulates with the acetabulum of the pelvic (hip) bone.

It is worth noting that part of the femoral neck is intracapsular and part is extracapsular. The hip joint is the junction where the hip joins the leg to the trunk of the body. Tightness in the lateral rotators and the ischiofemoral ligament limit internal rotation of the hip joint. The hip joint is innervated by the articular branches of multiple nerves that emerge from the lumbosacral plexus (L2-S1). It is covered by synovial membrane and carries a small branch of the obturator artery, the artery to the head of the femur, which contributes to the blood supply of the femoral head.
