![]() 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 complications of pelvic pathology in pediatrics can significantly affect the child's future, highlighting the importance of proper patient positioning 1. The AP pelvis view is a routine view for pediatric patients to examine the hip joints, proximal femora, iliac crests and pelvic ring. ![]() A new measurement-the Hip Value is based on measurements of the Idelberg- Frank angle, the Wiberg angle and MZ-distance of decentralization. Citation, DOI, disclosures and article data. Normal values of the hip joint for the evaluation of X-rays in children and adults. Excessive external rotation of a normal hip can also break Shenton’s line without subluxation of the femoral head. It is more important to look for the relationship between femoral head and acetabulum. It is performed with the patient supine on the X-ray table with the hip externally rotated and abducted. 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 babies and children with developmental dysplasia (dislocation) of the hip (DDH), the hip joint has not formed normally. In a normal hip, the ball at the upper end of the thighbone (femur) fits firmly into the socket, which is part of the large pelvis bone. ![]() Above the double standard deviation only severe dysplasias were present. Developmental Dislocation (Dysplasia) of the Hip (DDH) The hip is a ball-and-socket joint. 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.
