慢性肾脏病(CKD)5期患者常发生骨折,并导致病死率的上升。美国肾脏病资料系统显示,CKD患者髋骨骨折的发生率是一般人群的4倍以上,而且发生骨折以后的病死率是同年龄段、同病史、同透析病程患者的2倍。因此,了解骨折的危险因素将有助于预防骨折的发生。本文通过双能X线吸收法(DX Chronic kidney disease (CKD) 5 patients often fractures, and lead to increased mortality. The American Nephrology Information System shows that the incidence of hip fracture in patients with CKD is more than 4 times that of the general population, and the mortality after fracture is of the same age, with a history of 2 times that of patients with a history of dialysis. Therefore, understanding the risk of fractures will help prevent the occurrence of fractures. In this paper, dual-energy X-ray absorption method (DX
