Anterior Hip Anatomy

This joint serves as the main connection between the lower extremity and the trunk and typically works in a closed kinematic chain. The muscles of the thigh and lower back work together to keep the hip stable.

The hip joint is a ball and socket type joint.

Anterior hip anatomy. Detach rectus femoris from both its origins. The hip is a ball and socket joint in the engine room of human locomotion. Anatomy of the hip the hip joint.

The 2 hip bones form the bony pelvis. Direct anterior hip replacement is a minimally invasive surgical technique. Retract rectus femoris and iliopsoas medially and gluteus medius laterally to expose the hip capsule.

Lateral or external rotation 30 with the hip extended 50 with the hip flexed. In hip replacement surgery the hip can be reached through the back of the hip posterior approach the side of the hip lateral or anterolateral approach the front of the leg anterior approach or through a combination of approaches. The approach continues between the sartorius and tensor fascia lata muscles an internervous plane avoiding the risk of denervation of the involved muscles.

The movements of the hip joint is thus performed by a series of muscles which are here presented in order of importance with the range of motion from the neutral zero degree position indicated. Adduct and externally rotate the hip to place the capsule on stretch. When the cartilage in the hip joint starts to deteriorate the implications are profound.

Study of the anterior hip region. Anteroposterior and lateral radiographs of the hip. As a result today there is a range of surgical approaches being utilized by orthopedic surgeons.

The natural motion of the hip allows us to walk run swim cycle dance for those of us with rhythm and enjoy our lives as upright bipeds with grace. This approach involves a 3 to 4 inch incision on the front of the hip that allows the joint to be replaced by moving muscles aside along their natural tissue planes without detaching any tendons. Using the femoral head as a landmark the anterior synovial recess is identified.

The adult os coxae or hip bone is formed by the fusion of the ilium the ischium and the pubis which occurs by the end of the teenage years. The hip joint is the articulation of the pelvis with the femur which connects the axial skeleton with the lower extremity. The stability of the hip is increased by the strong ligaments that encircle the hip.

Muscles of the hip. The hip articulation is true diarthroidal ball and socket style joint formed from the head of the femur as it articulates with the acetabulum of the pelvis. In physiological conditions it is virtual whereas it is distended by anechoic fluid in the presence of joint effusion.

Identify plane between rectus femoris and gluteus medius. Illustration of the right hip demonstrates the location and size of the incision for the direct anterior approach.
