问题 单项选择题

股骨颈骨折的体征不包括()

A.患肢常有外旋畸形

B.患肢短缩

C.大转子突出

D.患髋轴向叩痛

E.Bryant三角底边延长

答案

参考答案:E

解析:

股骨颈骨折多见于中、老年人,常有摔倒受伤史;伤后感髋部疼痛,下肢活动受限,不能站立和行走。有时伤后并不立即出现活动障碍,仍能行走,但数天后,髋部疼痛加重,逐渐出现活动后疼痛更加重,甚至完全不能行走。检查时少有出现髋部肿胀及瘀斑,可出现局部压痛及轴向叩击痛。可发现患肢出现外旋畸形,一般在45°~60°之间。肢体测量可发现患肢缩短,大转子上移征(+),即①irant三角底边较健侧缩短;②大转子在Nelaton线之上;③两侧Shoe-make线向交之Kaplan点移至脐下对侧。Bryant三角:病人仰卧,沿髂前一上棘作一垂直线,在从大转子尖端画一水平线,即成一三角形。测其底线,与健侧对比,大转子上移时,此底线较健侧为短。Bryant三角>70°的股骨颈骨折,亦可适用于无移位的粗隆间骨折。Nelaton线:侧卧,髋关节屈90°~120°,自坐骨结节至髂前上棘的连线称为Nelaton线,正常时该线恰通过股骨大转子尖,当髋关节脱位或股骨颈折时,大转子尖可移位于此线上方。
