In this article, we shall look at the anatomy of. 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. By statistical methods, normal and pathological joints can be separated as follows: in adult Hip Values, between 6 and 15 indicate a normal joint form values between 16 and 21 indicate a slight deformation and values of 22 and above are indications of a severe deformation, in children in the normal range the Hip Value reaches 14 values of 15 and up are pathological. The hip joint is a ball and socket synovial joint, formed by an articulation between the pelvic acetabulum and the head of the femur. A new measurement-the Hip Value is based on measurements of the Idelberg- Frank angle, the Wiberg angle and MZ-distance of decentralization. It is more important to look for the relationship between femoral head and acetabulum. Investigations of the shaft-neck angle and the degree of anteversion including the wide standard deviation demonstrate that it is very difficult to determine where these angles become pathologic. Above the double standard deviation only severe dysplasias were present. Total hip replacement. Your doctor will remove both the damaged acetabulum and femoral head, and then position new metal, plastic or ceramic joint surfaces to restore the function of your hip.X-ray measurements of the hip joints of children, with special reference to the acetabular index, suggest that the upper standard deviation of normal comprises the borderline to a critical zone where extreme values of normal and pathologic hips were found together. Your doctor may recommend surgery if your pain from arthritis causes disability and is not relieved with nonsurgical treatment.
