目的：对脑瘫髋关节Ｘ线观察指标进行测量，了解患儿髋关节骨结构状况，提出发现此类患儿髋关节发育异常的便利方法及客观依据。方法：测量３．５～１３岁７４名脑瘫１４８个髋关节骨结构Ｘ线指标，测量项目有：髋臼指数、Ｓｈａｒｐ角、ＣＥ角、颈干角、头臼指数，并观察股骨头骺形态。结果：髋臼指数７°～３４°（１８．９６°±６．１３°）。Ｓｈａｒｐ角３３°～６５°（４８．６３°±４．５９°），ＣＥ角－１７°～４３°（１５．２５°±８．２１°），颈干角１２７°～１７３°（１４９．５０°±９．２５°），头臼指数４２～１１０（７６．６７±１０．３７），骺点位值－１１～４（－２．１９±２．３２）。显示髋臼指数异常的病例占１５％，Ｓｈａｒｐ角大于５０°占３５％，ＣＥ角小于２０°的为３３％，头臼指数异常为６８％，骺点位值小于－２的为４８．６５％，头骺形态发育好的圆型或椭圆型为６１％，发育差的扁平型或三角型为３９％。结论：部分脑瘫患儿存在髋关节发育异常，骺点位值方法较客观地反映股骨头骺中心点与髋臼相对位置关系，有实际应用价值。脑瘫髋关节发育特别是骨性发育异常包括髋臼发育不良和股骨头骺发育不良。髋臼和股骨头的相容性值得重视。具有行走能力患儿更?
OBJECTIVE: To measure the X-ray observation indexes of cerebral palsy, to understand the bone structure of the hip in children and to provide a convenient method and an objective basis for discovering the dysplasia of hip joint in these children. Methods: X-ray findings of 148 hip structures of 74 cerebral palsy patients aged 3.5-13 years were measured. The items of measurement included: acetabular index, Sharp angle, CE angle, cervical angle, head and socket index, and observation of epiphyseal morphology . Results: The acetabular index ranged from 7 ° to 34 ° (18.96 ° ± 6.13 °). Sharp angle 33 ° ~ 65 ° (48.63 ° ± 4.59 °), CE angle -17 ° ~ 43 ° (15.25 ° ± 8.21 °), neck angle 127 ° ~ 173 ° (149). 50 ° ± 9.25 °), head and mortar index 42 ~ 110 (76.67 ± 10.37), epiphysis point value -11 ~ 4 (-2.19 ± 2.32). 15% of patients with abnormal acetabular index, 35% of patients with Sharp angle greater than 50 °, 33% of patients with CE angle less than 20 °, 68% of abnormalities of the head and mortar index, 48.65 with epiphysis point less than -2 %, Round or oval morphology of well developed epiphysis was 61%, poorly developed flat or triangular type was 39%. Conclusion: Some children with cerebral palsy have hip dysplasia. The method of epiphyseal location value objectively reflects the relative position of epiphyseal center and acetabulum, and has practical value. Development of cerebral palsy, especially hip dysplasia, including acetabular dysplasia and femoral epiphyseal dysplasia. Acetabular and femoral head compatibility worth attention. Children with walking ability more?
