目的：分析老年髋部骨折患者骨折后D-二聚体变化规律及ROC曲线确定D-二聚体诊断老年髋部骨折患者深静脉血栓形成的诊断临界点。方法入院记录459例年龄≥50岁的髋部骨折患者血浆D-二聚体浓度，并应用SPSS 19.0软件进行统计学分析。结果老年髋部骨折患者，其D-二聚体有一个先降低后升高的趋势，转折点位于骨折后第3天；骨折后3天以内，其诊断临界点为12.13 mg/L；而3天后，其诊断临界点为2.79 mg/L。结论对于老年髋部骨折患者，骨折3天内、3天后应使用不同诊断临界点，以增加D-二聚体诊断深静脉血栓形成的准确性。

Objective To analyze the change in D-dimer and ROC curve in elderly patients with hip fracture and to determine the criti-cal diagnosis point of deep vein thrombosis in elderly patients with hip fracture. Methods The clinical data of 459 patients with hip fracture and the records of plasma content of D-dimer were retrospectively analyzed with the application of SPSS 19. 0 software for statistical analysis. Results In elderly patients with hip fracture,the plasma concentration of D-dimer had a trend with low at start before rising,the turning point was in 3 days after the fracture. Within 3 days after fracture,the critical point for diagnosis was 12. 13 mg/L. Three days later,the critical point for diag-nosis changed to 2. 79 mg/L. Conclusion For elderly patients with hip fracture,it should use different critical points of D-dimer for diagnosis after three days,in order to increase the diagnostic accuracy of D-dimer.
