Key result
In patients with lower extremity fractures, the incidence of deep vein thrombosis in the uninjured limb was 9.63% preoperatively and increased to 20.29% postoperatively.
Why the study?
The study was conducted to investigate the incidence of and independent risk factors for deep venous thrombosis in the uninjured limb, before and after operation, in patients with lower extremity fractures.
Observational (n=1,454)
No
The incidence of DVT in the uninjured lower extremity after fracture is substantial (9.63% preoperatively and 20.29% postoperatively) and warrants increased clinical attention.

DVT risk in uninjured limbs may warrant vigilance after lower extremity fractures; leaves open prospective validation of risk factors and screening.
Objective: The purpose of this study was to investigate the incidence of and independent risk factors for deep venous thrombosis (DVT) in the uninjured limb, before and after operation, in patients with lower extremity fractures.Methods: We collected the clinical data of patients with lower extremities fractures who presented at Xi’an Honghui Hospital between 1 July, 2015 and 31 October, 2017. Doppler ultrasonography was used to diagnose the DVT. Patients were examined pre- and postoperatively. The patients were then divided into a thrombosis group and a no thrombosis group according to the preoperative and postoperative ultrasonography results. The thrombosis group was defined as patients admitted to our hospital with DVT in the uninjured limb and the no thrombosis group was defined as patients without DVT in the uninjured limb.Results: This study enrolled 1454 patients who met the inclusion criteria. The incidence of preoperative DVT in the uninjured limb was 9.63% whereas the postoperative incidence was 20.29%. Age (OR=0.965, 95 CI%: 0.954 - 0.977; P=0.000) and gender (OR=0.667, 95% CI: 0.451-0.986, P=0.042) were independent risk factors for preoperative DVT in the uninjured limb. Blood loss (OR=0.997, 95 CI%: 0.995-1.000; P=0.020), D-dimer levels at admission (OR=0.941, 95 CI%: 0.887-0.999; P=0.045), and postoperative day 5 D-dimer levels (OR=0.889, 95 CI%: 0.819-0.965; P=0.005), were independent risk factors for postoperative DVT in the uninjured limb.Conclusion: In conclusion, the actual incidence of DVT in the uninjured lower extremity after fracture may currently be underestimated and should be pay more attention.
