摘　　要：目的探讨儿童股骨头坏死后对颈干角发育的影响。方法在52例单侧股骨头坏死的儿童骨盆X线平片上,进行颈干角的测量(包括患侧和健侧),并按照年龄及病情进行分组比较。结果 52例股骨头坏死均为单侧发病,其中右侧20例,左侧32例,按照Catterall标准:Ⅰ、Ⅱ型分别有7例和16例(A组),Ⅲ、Ⅳ型分别有21例和8例(B组)。颈干角患侧148.9°±13.3°,健侧156.1°±10.2°,健患两侧比较差异有统计学意义(P均<0.01);A组颈干角患侧较健侧小6.2°±2.3°,B组颈干角变小9.8°±3.7°,A、B组间比较差异有统计学意义(P均<0.01)。发病年龄<9岁患儿组颈干角患侧较健侧小7.3°±3.1°,≥9岁患儿组颈干角小9.2°±4.3°,两者比较差异无统计学意义(P>0.05)。结论儿童股骨头坏死会影响股骨颈的发育和塑形,使颈干角变小,且病情越严重,后遗影响可能越大。Objective To study the influences of Perthes disease on the development of neck shaft angle（NSA）. Methoods We measured NSA in the 52 cases with unilateral usteonecrosis of the femoral head of tile pelvic X - ray of the children, and compared the re- suits in groups accroding to age and patient＇s condition. Results The 52 cases all were attacked unilaterally, 20 cases of them occurred on the right, 32 cases on the left. Accroding to Catterall standards： there were 7 cases in type I , 16 cases in type Ⅱ （group A） , 21 cases in type HI , 8 cases in type IV （group B）. The NSA of the affected side was 148.9° ±13.3°. the normal side was 156. 1° ± 10.2°. In group A, the NSA of diseased side decreased by 6.2°± 2.3°than the normal side. In group B, the NSA of diseased side decreased l）y 9.8° ± 3.7°. The comparison between groups mentioned above had significant difference（ P 〈 0.01 ）. In the group of sick children whose age of onset were less than 9 years oht. The NSA of the affected side was 7.3° ±3.1°, smaller than the normal side. In the group of more than 9 years old, the NSA of the affected side was 9.2° ± 4.3°, smaller than the normal side.There were no significant difference be- tween the two groups（ P 〉0.05 ）. Conlusion Perthes disease can influence the development and reconstruction of NSA, and also be able to lessen the NSA. Furthermore, the worse of illness, possibly the more obvious the sequelae could be.
