婴儿髋关节超声检查床临床应用研究

目的:探讨自制婴儿髋关节超声检查床在婴儿发育性髋关节发育不良超声筛查中的应用效果.方法 :选择160名(320个髋关节)出生后42 d的婴儿进行髋关节超声检查.3名超声医生首先用普通检查床,徒手固定婴儿臀部及下肢进行检查;随后应用婴儿髋关节超声检查床再次检查,并对比在2种不同检查床条件下超声测量数据.结果 :应用婴儿髋关节检查床总体检查的结果左右侧α角和β角差异均显著小于普通检查床检查的结果(P<0.01),右侧股骨头覆盖率检查的总体结果差异显著低于普通检查床检查的结果(P<0.01);使用普通检查床3名医生测量结果之间内部相关系数均<0.4,一致性较差,使用本研究设计婴儿髋关节超声检查床后内部相关系数均>0.75,一致性较好.结论 :婴儿髋关节超声检查床的应用可明显减少人为因素误差,降低数据变异度.

Research on clinical application of the ultrasonic examining bed in infant hip joint

Objective:To investigate the effects of self-made ultrasonic examining bed in the screening of development dislocation of hip( DDH) . Methods:Three hundred and twenty hip joints in 160 infants born more than 42 days were detected by ultrasound. The cases were examined using common examining bed combined with fixing the infant hip and lower limbs by hand by three doctors,and the cases were examined using infant hip joint ultrasonic examining bed again. The examining date between two methods were compared. Results:The deviation of α angle and β angle in left and right sides detected by infant hip joint examining bed were significantly less than those detected by the common bed(P <0. 01). The difference of right side total result detected by FHC was significantly less than that of common bed(P<0. 01). The intraclass correlation coefficient(ICC) of examination result using common bed by three doctors was less than 0. 4,the consistency of which was poor. The intraclass correlation coefficient of examination result using infant hip joint examining bed was more than 0. 75,the consistency of which was good. Conclusions:Ultrasonic examining bed for infant hip joint can significantly eliminate the anthropic factor influencing,and reduce the degree variation of date.
