Abstract

PURPOSE

This study aimed to investigate the detection rate of developmental dysplasia of the hip (DDH) by ultrasound. To obtain the distribution characteristics of the different types (I-IV) and the role of ultrasound in the evaluation of infants with DDH (type IIc and above) receiving conservative treatment.

METHODS

A retrospective analysis was performed. The chi-square test was used for comparisons between count-data groups. Two-sided tests were used for all analyses. The results of ultrasound follow-up after conservative treatment are described.

RESULTS

Among the 48 666 infants examined, the detection rates were as follows: type I, 95.42%; IIa, 3.18%; IIb, 0.91%; IIc, 0.22%; D, 0.01%; III, 0.14%; and IV, 0.12%. There were 4456 hips with IIa and above, more left (54.65%) than right (45.35%) hips, and more females (82.60%) than males (17.40%). The detection rate of type IIa and above was 4.58%, and that of type IIb and above was 1.40%. After the treatment, the α value increased, and β value decreased. The cure rate of the less-than-42-days group was higher than that of the other groups.

CONCLUSION

The ultrasound detection rate of DDH is high. DDH was more likely to occur on the left side and in females. It is recommended that the infants should be treated within 42 days.

摘要

目的

本研究旨在探讨超声对发育性髋关节发育不良（DDH）的检出率。获得不同类型（I-IV 型）的分布特征，以及超声在评估接受保守治疗的 DDH 患儿（IIc 型及以上）中的作用。

方法

回顾性分析。计数资料组间比较采用卡方检验。所有分析均采用双侧检验。描述了保守治疗后超声随访的结果。

结果

在 48666 例受检婴儿中，检出率如下：I 型，95.42%；IIa 型，3.18%；IIb 型，0.91%；IIc 型，0.22%；D 型，0.01%；III 型，0.14%；IV 型，0.12%。4456 髋存在 IIa 及以上类型，左侧（54.65%）多于右侧（45.35%），女性（82.60%）多于男性（17.40%）。IIa 及以上类型的检出率为 4.58%，IIb 及以上类型的检出率为 1.40%。治疗后，α 值增加，β 值减少。42 天内治疗组的治愈率较高。
