At an average follow-up of 2.1 years, we reviewed the records of 241 patients who had had a fracture of the hip. The average age of the patients was 75.4 years. The rate of mortality one year after the fracture was 21.6 per cent for the total group, 8.0 per cent for the low-risk group, and 49.4 per cent for the high-risk group. The standard mortality ratio was six times higher for the high-risk group than for the general population (individuals who did not have a fracture), matched for age. It was highest for patients who were less than seventy years old and lowest for those who were older than eighty. However, in the second year after the fracture, the standard mortality ratio approached unity--that is, the rate of mortality approached that of the general population. The results suggest that there is an inverse relationship between mortality and advanced age and that the impact of a fracture of the hip on mortality is seen primarily in the first year after injury.
在平均2.1年的随访期内，我们查阅了241例髋部骨折患者的记录。患者的平均年龄为75.4岁。骨折后一年的总死亡率为21.6%，低风险组为8.0%，高风险组为49.4%。高风险组的标准化死亡率比年龄匹配的一般人群（未发生骨折的个体）高六倍。70岁以下患者的标准化死亡率最高，80岁以上患者的标准化死亡率最低。然而，在骨折后的第二年，标准化死亡率接近1，即死亡率接近一般人群的死亡率。结果表明，死亡率与高龄呈负相关，髋部骨折对死亡率的影响主要在受伤后的第一年显现。
