超声在先天性髋关节脱位中的早期诊断准确率分析

Analysis of the accuracy of ultrasond in the early diagnosis of congenital dislocation of the hip

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。

Objective To investigate the early diagnostic methods of B-mode uhrasonography in neonatal hip anatomy and congenital dislocation of the hip. Methods The results of B-mode ultrasonography 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 Bmode ultrasound can discover the congenital dislocation and dysplasia of the hip early, it is simple, economy, painless and has no radioactive damage.
