髋部骨折患者中股骨颈强度的测定

Determination of strength of femoral neck in patients with hip fracture

目的:了解老年髋部骨折和老年骨质疏松的关系。方法:选择1998年至2003年收治的50岁以上老年髋部骨折80例,测定其健侧股骨上端强度(Singh指数),同时选择门诊50岁以上其他原因摄骨盆X线片而无骨盆和股骨上端骨折的患者90例,测定其左侧股骨上端强度,将测得的数值作对比分析。结果:50～60岁组和61～70岁组股骨上端强度与对照组比较差异有统计学意义(P<0.01),而70岁以上组的强度与对照组比较差异无统计学意义(P>0.05)。结论:老年髋部骨折患者其股骨上端强度明显下降,测定Singh指数对预测髋部骨折有重要意义。

Objective：To study the relationship between the hip fracture and osteoporosis of the aged. Methods：The strength of contralateral unfractured proximal femur（Singh index）in 80 patients with hip fractures from 1998 to 2003 were collected ,and the patients＇ age were all over 50 years. At the same time, the strength of proximal femur of 90 patients without fractures were also measured, and the figures were analyzed. Results：The results showed that the fractures of proximal femur was closely related to osteoporosis in 50-60 age group and 61-70 age group （P〈0.01）. The relationship was not obvious when the age was over 70（P〉0.05 ）. Conclusion：The strength of proximal femur in patients with hip fracture was obvious decreased.The Singh index of proximal femur can be helpful in forecasting the possibility of proximal femur fracture.
