Hip fracture may be referred to the supracondylar knee. On examination, the affected extremity is often shortened and unnaturally, externally rotated compared to the unaffected leg. Hip fracture following a fall is likely to be a pathological fracture. The most common causes of weakness in bone are: The hip joint, an enarthrodial joint, can be described as a ball and socket joint. The femur connects at the acetabulum of the pelvis and projects laterally before angling medially and inferiorly to form the knee. Although this joint has three degrees of freedom, it is still stable due to the interaction of ligaments and
X-ray of hip dysplasia be drawn in the pediatric pelvis assessing hip dysplasia are as follows: In the adult hip there are important landmarks to be recognized on plain film radiographs (Figure 5): In the adult hip, normal joint space ranges from 3 to 5 mm and must be uniform. Values under 2 mm are consistent with joint space narrowing. The most important measurements are detailed in Figure 6 and Table 1. Figure 6: Acetabular depth value under 250 characterizes the dysplastic hip. In normal conditions the acetabulum covers 75% of the femoral head. This coverage can be determined by three different measurements: lateral
