Predictive model for preoperative deep vein thrombosis in distal femur fractures using inflammatory blood markers: a single-center retrospective cohort study.

Among the preoperative inflammatory indicators evaluated, NLR, lymphocyte-to-monocyte ratio, white blood cell count, neutrophil count, lymphocyte count, and eosinophil count were identified as independent determinants of preoperative lower limb deep vein thrombosis in patients with distal femur fractures.

The predictive model constructed based on independent risk factors has excellent predictive efficacy and clinical application value.
