摘要
目的探讨髋关节外展锻炼对GrafⅡa型髋关节患儿的近期干预效果。方法选取2017年1月至2017年6月在海盐县妇幼保健院出生并应用超声静态Graf法诊断为GrafⅡa型髋关节78例患儿(90髋)为研究对象,将患儿随机分为干预组41例(47髋)和对照组37例(43髋),干预组采用髋关节外展锻炼,对照组不给予外展锻炼,1~2月后复查超声并对比两组婴儿髋关节骨顶角(α角)发育改善情况。干预组及对照组组间及组内患儿的初查年龄、复查年龄、复查间隔、初查骨顶角度、复查骨顶角度、改善骨顶角度比较采用t检验,患儿性别比组间比较采用χ2检验。结果干预组及对照组骨顶角α角均较前增加,差异均有统计学意义(t=12.71、13.63,P均<0.001),且干预组骨顶角α角增加幅度高于对照组,差异有统计学意义(t=2.219,P=0.029)。两组患儿性别比、初查年龄、复查年龄、复查间隔一般资料比较,差异均无统计学意义(P均>0.05)。结论与自然转归相比,髋关节外展锻炼近期能更好地促进GrafⅡa型髋关节发育成熟。
Objective To analyze short-term effects of hip abduction exercise on Graf type IIa hip joint in infants.Methods A total of 78 infants born at Haiyan County Maternal and Child Health Hospital from January 2017 to June 2017 were diagnosed with Graf type II a hip joints(90 hips)by ultrasound using the static Graf method.They were selected and randomly divided into either an intervention group(n=41,47 hips)or a control group(n=37,43 hips).The intervention group was treated by hip abduction exercise,while the control group did not.After 1~2 months,ultrasound examination was performed to compare the improvement of theαangle in the two groups.The Student′s t-test was used for comparing the age at initial examination,age at reexamination,interval of reexamination,initialαangle,αangle at reexamination,and the improvement of theαangle between the intervention group and the control group.Theχ2 test was used to compare the sex ratio of the infants between the two groups.Results Theαangle increased in both the intervention group and control group(t=12.71 and 13.63,respectively,P<0.001),and the improvement ofαangle in the intervention group was more significant than that in the control group(t=2.219,P=0.029).There were no significant differences in the gender ratio,age at initial examination,age at reexamination,or interval of reexamination between the two groups(P>0.05).Conclusion Compared with the natural outcome,hip abduction exercise can promote Graf IIa hip joint maturity in the short term.
