Anatomical and radiographic study of arthrosis of the hip. Statistics.
The most important points in this study of 147 patients with arthrosis of the hip are the following: 1. Unilateral arthrosis has a distinctive behaviour pattern. 2. There are migratory and non-migratory and non-migratory types. The most common migration is supero-lateral. 3. Arthrosis of the hip is a biological process which can be divided into four stages. 4. Narrowing of the joint space is focal. 5. Cysts are seen frequently on both the acetabular side and in the head of the femur. They form after the overlying cartilage layer has disappeared. 6. Six types of osteophytes are identifiable, the most common being in relation to the inferior aspect of the calcar or femoral head. 7. Acetabular dysplasia, evaulated by using parameters of measurement (acetabular angle, depth, slope of roof and Wiberg's CE angle) was present in over half of our cases of arthrosis of the hip.
