The hip joints are the main linkbetween the lower limbs and torso. The weight of the body gets transmitted by these two joints in the leg. They are surrounded by many large muscles, so it is difficult to feel and look.

Hip is a single commune, because it allows movement in all directions and at the same time, it is very stable. Movement and stability are possible because of spherical structure (see graphic below). Additional stability is provided by strong ligaments.
Sometimes this stability of the hip joint is compromised when the fetus develops in the womb. This causes the ball out of the Cup. This condition is called congenital dislocation of hip
The ball is at the head of the femur and the socket is the acetabulum. The acetabulum is the bony basin. They are surrounded by the capsule (fibrous structure attaching to the bone and enveloping the articulation). The capsule is reinforced by three ligaments (fibrous difficult as attaching structures bone to bone).
The hip joint is bordered by a smooth fabric, tough and resilient called cartilage. This fabric allows a smooth movement of the joint. In osteoarthritis of the hip, this tissue gets thinned down and worn out.
STRUCTURE OF THE HIP JOINT
First is the attribution or the ligament Y. It is the hardest ligament and is located towards the front (in front). It is stretched in extension and therefore stabilizes the hip position stand. Anatomy (below) is the pubofemoral ligament. Subsequent is the ischiofemoral ligament.
Further deepening this articulation is a fibro-cartilaginous rim attached to the margin of the acetabulum called acetabular labrum. A ligament attaches to the head of the femur called round ligament. It provides a passage to the blood vesselssupplying the head of the femur during growth.
The internal aspect of the joint is bordered by the synovial membrane. On the neck of the femur, the synovial membrane is folded into ridges called retinacula. What are the arteries closed and the main blood supply to the head of the femur. These arteries can easily be disrupted by a neck femur Fracture displaced. Many other conditions can also disrupt the blood supply of femoral head, such as alcoholism and the use of steroids. This can cause a disease called avascular necrosis.
When the head blood supply is disrupted during childhood, resulting in deformation of the head. This condition is known as Perthes disease.
Many muscles are acting through the joint and cause different movements. The movements which occur in the hip joint are
1.Flexion: approximation of the thigh at the front of the torso.
2.Extension: movement of the arm back. It is very limited by the ligament of Y.
3.Adduction: movement of the domestic everywhere and on the side of the thigh.
4.Abduction: branch laterally away from the body movement.
5.Rotation: movement in a circle on one point.
Major muscles causing the bending is the iliopsoas. Expander is the diaper. The removal is by gluteus medius and minimus. Supply by the adductor group of muscles.
