目的 婴幼儿髋关节发育不良(developmental dysplasia of the hip,DDH)目前最有效、最简捷的方法是采用闭合复位治疗。通过对3周岁以下不同年龄段、单侧DDH患儿闭合复位治疗结果进行分析,探讨年龄因素对DDH闭合复位治疗疗效及预后的影响。方法自1982~1996年采用闭合复位治疗3周岁以下DDH413例(共545髋),随机选用<1周岁、1~2周岁、>2周岁的单侧完全性DDH各 30例。测定(量)各病例复位前及复位后 6、12、24个月患侧、正常侧髋臼指数(the acetabular index,AI)、髓臼指数深宽比[the ratio of depth to width of AI,AI(D/W)]和治疗后12、24个月股骨头中心距离差数百分比(centre-head distance discrepancy, CHDD)。结果 各年龄组单侧 DDH经闭合复位治疗后24个月时,各组患侧髓臼与正常侧髓臼 AI差值中位数:< 1岁组 4°,1~ 2岁组 5. 5°,> 2岁组8°患侧髋臼与正常侧髓臼AI(D/W)间平均差值:<1岁组2.60%,1-2岁组5.25%,>2岁组12.03%。各组CHDD差值中?
To study the relationship between the age of the patients undergone closed reduction and the development of the acetabulum in patients with developmental dysplasia of the hip (DDH). Methods From 1982 to 1996 a total of 413 cases(545 hips) of DDH under 3 years of age were treated with closed reduction. Three groups each consisting of 30 cases of unilateral complete DDH were randomly selected for this study. Group 1 belonged to the age range of one year, group 2, 1-2 years, and group 3, over 2 years. Before the reduction and 6, 12, 24 months after closed reduction, data of the acetabular index (Al), ratio of depth to width of AI[AI (D/W) ] of the lesional and normal acetabulum and the 12, 24 months centre-head distance discrepancy(CHDD) were obtained by measurements. Results 24 months after the treatment, the difference of AI between the abnormal and normal acetabulum were: 4° in group l, 5. 5° in group 2, and 8° in group 3. The average difference of AI of the abnormal and the normal acetabulum (D/W) were: 2. 60% in group 1, 5. 25% in group 2, and 12. 03% in group 3. The average difference of CHDD was: 2% in group 1, 3% in group 2, and 1% in group 3. Conclusion During the treatment of DDH with closed reduction in the age range of under 3 years, the AI of the lesional acetabulum decreased in each group and the results were closely related with the basic figure before the commencement of the treatment, the AI of the lesional acetabulunm AI(D/W) increased in each group, apparently there is a relation with the basic figures as well as a linkage with the age factor. In patients of less than 2 years old, there was a relative larger decrease of CHDD, in cases of more than 2 years of age the change of CHDD was not obvious. There is still a question for using CHDD ≤6% as a standard of judgement for the unilateral DDH following treatment for 12 months. The application of CHDD ≤ 9% as the judgement factor seemed to be more in concert with results of practical clinical observations.
