Abstract

Objective:

To clarify if fracture site is correlated to the occurrence of deep venous thrombosis, and determine the risk factors of deep venous thrombosis in lower extremity fractures, help surgeons make prophylaxis for the disease correctly.

Methods:

The patients with lower extremity fractures treated surgically in the orthopedics department of our hospital from May 2012 to July 2017 were reviewed retrospectively. The clinical data including age, gender, fracture site, surgery modality, hospital stay, operation time, occupation type, hypertension, coronary heart disease, diabetes, smoking status, drinking status, postoperative exercises were collected and analyzed.

Results:

Eight hundred and twenty-nine patients were included for analysis, in which 68 were included in deep venous thrombosis group, 761 were included in the non-deep venous thrombosis group, and the incidence of deep venous thrombosis was 8.2%. There were significant differences in age, fracture site, surgery modality, occupation type, operation time, smoking status, hospital stay and postoperative exercises between the two groups (p<0.05), but no significant differences in gender, drinking status, coronary heart disease, diabetes and hypertension (p>0.05). In multivariate analysis, old age greater than 50 years, arthroplasty and operation time more than three hours were independent risk factors, while physical labor and postoperative exercises were protective factors for deep venous thrombosis in lower extremity fractures.

Conclusion:

Fracture site was correlated to the incidence of deep venous thrombosis, old age, longer operation time, and arthroplasty were independent risk factors, physical labor and postoperative exercises were protective factors for deep venous thrombosis in patients with lower extremity fractures.
