髋臼骨折病人(伴或不伴股骨头脱位)在确定关节内是否有骨折碎片及其性质时,作CT横断面观察是有益的。1例患者的一般X线片提示有明显的关节内碎片,而CT检查则明确那只是一个无移位的股骨头骨折,从而避免了不必要的再次手术。CT扫描仪可将某些重要部位投影放大。CT检查比常规X线摄片更能明确髋臼复杂骨折的形态,包括骨折片的性质、位置、骨折片间的立体关系、关节间隙的状态、间隙内有无骨折 Acetabular fracture patients (with or without femoral head dislocation) in the determination of joint fragments and the nature of the fracture, the CT cross-sectional observation is beneficial. The plain radiographs of 1 patient showed significant intra-articular fragments, whereas the CT scan revealed that it was a non-displaced femoral head fracture, thus avoiding unnecessary reoperation. CT scanners can highlight some important parts of the projection. Computed tomography (CT) can confirm the shape of complex acetabular fractures more than conventional radiography, including the nature and location of the fractured disc, the three-dimensional relationship between the fractures, the status of the joint space, and the presence or absence of fractures
