摘要
为了探索先天性髋关节脱位术后再脱位的原因，对１９８５年～１９９５年手术治疗的１０６例（１２８侧）小儿先天性髋关节脱位进行了随访，发现有７例再脱位。根据Ｘ线片上髋臼指数、头滴骶比值、股骨头上移程度，对再脱位原因进行分析。结果表明，术后再脱位与多因素作用有关，主要是手术后髋臼指数回升，髋臼内软组织残留，股骨颈前倾角过大和髋臼与股骨头之间压力过大。提示防止小儿先天性髋关节脱位术后再脱位，应针对造成再脱位的原因。
Redislocation of the femoral head may be occured after its operative reduction in the congenital dislocation of the hip, therefore, it is greatly important to disclose the causes of the redislocation in order to avoid this every complication and improve the curative effect of this operation. Seven cases of redislocation from 106 cases (128 sides) of the congenital dislocation of the hip which had been reduced operatively were studied with relative measurements of the hip joints on roentgenogram, associated their pathologic conditions described in operation. The results showed that, in these cases, there were (0.843±0.692)cm upward displacement of the femoral head beyond the horizontal Y line, (68.86±0.692) degree of the femoral anteversion, the more lateral displacement of the femoral head compared to the opposite side and the acetabular index increasing up to (33.86±3.72) degree from (26.14±2.73) degree of the operative correction. These phenomena indicate that the redislocation after operative reduction of the femoral head in congenital dislocation of the hip is mainly related to four causes which include the existence of large pressure between acetabulum and femoral head, the uncorrected abnormal femoral anteversion, the residue of the pathologic tissues in the acetabulum and the reascending of the acetabular index having been corrected in operation.
