超声在先天性髋关节脱位中的早期诊断准确率分析

摘要

Objective To investigate the early diagnostic methods of B-mode ultrasonography in neonatal hip anatomy and congenital dislocation of the hip. Methods The results of B-mode ultrasonog-raphy of bilateral hip joints of 1083 cases neonatus were analyzed retrospectively. Results There was 1 case of congenital subluxation of hip unilateral. The α,β angle,acetabular index and morin ratio of the neonatal hip on the hip joint coronal plane sonogram echogram were measured,and the normal values were:65. 10° ± 5. 10°,40. 27° ± 6. 14°,24. 75° ± 4. 29°,(64. 66 ± 5. 63)% . Conclusions The B-mode ultrasound can discover the congenital dislocation and dysplasia of the hip early,it is simple,econ-omy,painless and has no radioactive damage.%目的：探讨新生儿髋关节的超声解剖和先天性髋关节脱位的 B 超早期诊断方法。方法回顾性分析1083例新生儿两侧髋关节 B 超检查结果。结果发现先天性髋关节半脱位1例，在髋关节冠状面声像图上分别测量新生儿髋关节的α角、β角、髋臼指数和股骨头骨性髋臼覆盖率，其正常值分别为：65.10°±5.10°、40.27°±6.14°、24.75°±4.29°、（64.66±5.63）%。结论 B 超能早期发现先天性髋关节脱位及发育不良，操作简单、经济、无痛、无放射性损害。
