超声诊断早产儿髋关节异常

Ultrasound diagnosis of developmental dysplasia of hip in premature infants

目的:探讨早产儿发育性髋关节异常(developmental dysplasia of hip,DDH)的发生率及超声诊断价值。方法:采用Graf静态检查法超声检查109例早产儿的髋关节,并对结果进行统计分析。结果:109例中,髋关节不稳定22例(20.2%);DDH26例(23.9%),其中髋关节发育不良15例,髋关节半脱位2例,髋关节脱位9例。与正常儿差异有统计学意义(P<0.05)。孕龄<34周的早产儿DDH发生率高于孕龄34～37周的早产儿(P<0.01)。结论:早产儿,尤其是孕龄<34周的早产儿,易患DDH。超声检查可以早发现,早诊断,早干预。

Objective：To explore the incidence of developmental dysplasia of hip（DDH） in premature infants and the role of ultrasonography in diagnosis of DDH.Methods：One hundred and nine premature infants were received ultrasonography of the hip,and the results were analyzed statistically.Results：Unstable hips were detected in 22 premature infants（20.2%） and DDH in 26（23.9%）.Among the 26 premature infants of DDH,15 had hip dysplasia,2 hip subluxation and 9 hip dislocation.The difference was significant between premature infants and normal term infants（P0.05）.The incidence of DDH was higher in infants with a gestational age of less than 34 weeks than in those with a gestational age of 34 weeks to 37 weeks（P0.01）.Conclusions：As there is a high incidence of DDH in premature infants,especially in infants with a gestational age of less than 34 weeks,it is suggested that each premature infant receives ultrasonography of the hip so that early intervention could be applied.
