![]() 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. ![]() 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. Pelvis radiographs share the same limitations in sensitivity and specificity for fracture detection as hip radiographs, and a negative radiograph alone cannot. On the other hand, only 21 of the patients with hip arthritis on x-rays were frequently painful. Only 16 of hips in patients with frequent hip pain had x-ray evidence of hip arthritis. 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. In the Framingham study, the researchers looked at the hip x-rays of 946 patients. ![]() Above the double standard deviation only severe dysplasias were present. 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. ![]()
