骨科英文书籍精读(229)|股骨颈骨折(2)
中国十大名师之一赖世雄老师说过,学习英语没有捷径,少就是多,快就是慢。不要以量取胜,把一个音标、一个单词、一段对话、一篇文章彻底搞透,慢慢积累,你会发现,你并不比每天走马观花的输入大量英文学的差。
Mechanism of injury
The fracture usually results from a simple fall; however, in very osteoporotic people, less force is required–perhaps no more than catching a toe in the carpet and twisting the hip into external rotation. Some patients may have experienced minor symptoms of a preceding stress fracture of the femoral neck. In younger individuals, the usual cause is a fall from a height or a blow sustained in a road accident. These patients often have multiple injuries and in 20 percent there is an associated fracture of the femoral shaft. Occasionally, stress fractures of the femoral neck occur in runners or military personnel.

损伤机制
骨折通常是由简单的摔倒造成的;然而,对于骨质疏松症患者来说,所需的力量要少得多——也许只不过是在地毯上抓住一个脚趾,然后扭动臀部进行外旋。有些病人可能经历过股骨颈应力性骨折的轻微症状。对于年轻人来说,常见的原因是从高处坠落或在交通事故中遭受打击。这些患者通常有多处损伤,20%的患者伴有股骨干骨折。偶尔,跑步者或军人会发生股骨颈应力性骨折。
