Hip fractures are common in elderly women, and early risk assessment of future hip fractures is relevant in relation to prevention. We studied the predictive value of radial and humeral fractures in women. The influence of weather conditions on the risk was also studied. Women aged 20-99 years with a fracture of the distal radius (n = 1162) or proximal humerus (n = 406) were followed for 0 to 9 years. The relative risk (RR) and 95% confidence limits (CL) of subsequent fracture among women suffering radial or humeral fractures compared with the background population were calculated. Women 60-79 years of age who had suffered a fracture of the distal radius or proximal humerus had relative risks of sustaining a hip fracture of 1.9 (1.3-2.6, 95% CL) and 2.5 (1.3-3.6, 95% CL) respectively. The relative risk of hip fracture was highest within the first years following a fracture of the radius or the humerus. Women suffering an upper extremity fracture (radius or humerus) in snowy or icy weather had a marginally increased risk (RR = 1.3, 0.4-2.3, 95% CL and RR = 1.8, 0.3-3.4, 95% CL) for a later hip fracture. A woman 50 years old with a radial or a humeral fracture had an estimated residual lifetime risk of sustaining a subsequent hip fracture of 17% and 16% respectively compared with 11% for the background population.(ABSTRACT TRUNCATED AT 250 WORDS)
髋部骨折在老年女性中很常见，对未来髋部骨折进行早期风险评估对于预防工作具有重要意义。我们研究了女性桡骨和肱骨骨折的预测价值。还研究了天气状况对风险的影响。对年龄在20 - 99岁之间发生桡骨远端骨折（n = 1162）或肱骨近端骨折（n = 406）的女性进行了0至9年的随访。计算了桡骨或肱骨骨折女性与背景人群相比后续骨折的相对风险（RR）及95%置信区间（CL）水平。年龄在60 - 79岁之间发生桡骨远端或肱骨近端骨折的女性，发生髋部骨折的相对风险分别为1.9（1.3 - 2.6，95% CL）和2.5（1.3 - 3.6，95% CL）。桡骨或肱骨骨折后的头几年内髋部骨折的相对风险最高。在雪天或结冰天气发生上肢骨折（桡骨或肱骨）的女性，后期发生髋部骨折的风险略有增加（RR = 1.3，0.4 - 2.3，95% CL和RR = 1.8，0.3 - 3.4，95% CL）。一名50岁发生桡骨或肱骨骨折的女性，与背景人群11%的风险相比，其后续发生髋部骨折的估计终生残余风险分别为17%和16%。（摘要截选至250字）
