目的 观察 6个月以下髋脱位患儿初次治疗年龄与Pavlik支具应用时间之间的关系 ,探讨患儿各初次治疗年龄组和各Pavlik支具应用时间组髋臼指数和Y -协调指数的变化情况。方法 本研究共随访了 1994年 1月至 2 0 0 2年 12月间我院采用Pavlik支具治疗的先天性髋关节脱位患儿 30例 (4 2个髋关节 )。随访期限为 9.4～ 81个月 ,平均随访时间为 32 .9个月 ,初次就诊年龄介于生后 0 .5 3～ 8个月之间 (6个月以上者只有 1例 ) ,平均初次就诊年龄为生后 2 .9个月 ,Pavlik支具应用的时间为 3～ 9个月 ,平均应用时间为 4 .7个月。结果 本文所得的复位成功率为 91.2 % ,无一例患儿发生股骨头坏死。 6个月以下患儿各初治年龄组的支具应用时间之间差异不显著 ,各支具应用时间组的患儿初治年龄之间也没有差异。支具应用 6个月时 90 .5 %的患儿可以去除支具。具有完整资料的34个脱位髋关节初次治疗时的髋臼指数均值为 30 .6 2°,其标准差为 6 .5 6°。本次随访所得髋臼指数的均值为 18.75° ,其标准差为 5 .78°。髋臼指数的前后变化差异有非常显著性意义 (P <0 .0 0 1)。本次记录的反映髋关节脱位治疗前后股骨头与髋臼同心情况的Y 协调指数 ,在初次治疗时其均值为 0 .94 ,标准差为 0 .0 6 ;而在随访时所得的均值为 0 .8
Objective To observe the relationship between the initial treatment age and the application time of Pavlik brace in children younger than 6 months and to explore the change of acetabular index and Y - coordination index in each primary treatment group and each Pavlik brace application time group Happening. Methods A total of 30 children (42 hips) with congenital dislocation of the hip joint treated with Pavlik brace in our hospital from January 1994 to December 2002 were followed up. The follow-up period ranged from 9.4 to 81 months with an average follow-up of 32.9 months. The initial treatment was between 0.53 and 8 months after birth (only 1 patient was older than 6 months), and the average initial visit Pavlik Bracelet application period of 3 to 9 months, the average application time of 2.7 months, the age of 2.9 months after birth. Results The success rate of this article was 91.2%, none of the patients had avascular necrosis of the femoral head. There was no significant difference in the duration of application of braces among children under the age of 6 months or less in each age group. There was no difference in the age of first trimester between the two groups. At 6 months, 90.5% of children with braces removed the brace. The mean value of acetabular index of the 34 primary dislocated hip joints with complete data was 30.62 ° and the standard deviation was 6.56 °. The average acetabular index obtained at this follow-up was 18.75 ° with a standard deviation of 5.78 °. The difference of acetabular index before and after the change was very significant (P <0.01). The recorded Y coordination index reflecting the concentricity of the femoral head and the acetabulum before and after the treatment of dislocation of the hip showed an average of 0.94 at the initial treatment and a standard deviation of 0.06 while the mean obtained at follow-up was 0 .8
