自19世纪伦琴发现 X 线以来,X 线诊断技术有了很大的发展。然而,直到1971年第一台 CT 扫描器诞生,1972年 Hounsfield 报道70例病人经 CT 检查而明确诊断后,X 线诊断技术才真正有了一个飞跃。髋关节和骨盆 CT 拍摄的截面图能非常有效地将髋关节创伤组成立体形象,清楚地显示出髋臼、股骨头、内侧骨盆壁及股骨头、颈间的骺线。治疗中须考虑的因素有骨片碎裂程度、髋臼前后壁是否完整、骨片的大小、臼底骨折股骨头向盆腔内移位程度以及关节内有无碎片等,CT 对此均能作出准确的判断。CT 可在仰卧位时进行,骨折病人在牵引中即可作
X-ray diagnostic techniques have greatly evolved since X-Rance was discovered in the 19th century. However, X-ray diagnostic techniques did not really make a big leap until the first CT scanner was introduced in 1971 and Hounsfield in 1972 reported 70 patients confirmed by CT examination. Hip and pelvis CT cross-sectional images can be very effective in the formation of three-dimensional image of the hip joint trauma, clearly shows the acetabulum, femoral head, medial pelvic wall and femoral head, epiphyseal line between the neck. The factors to be considered in the treatment are the degree of fragmentation, the integrity of the anterior and posterior wall of the acetabulum, the size of the bone fragment, the degree of displacement of the femoral head from the mortar to the pelvic cavity, and the presence or absence of debris in the joint. CT can do this Accurate judgment. CT can be carried out in the supine position, fracture patients can be made in the traction
