The incidence of deep vein thrombosis and pulmonary embolism after fracture of the tibia: An analysis of the National Trauma Databank.

Controversy exists regarding the routine use of chemical prophylaxis in isolated lower extremity fractures. The incidence of VTE in specific fracture locations in the lower extremity is largely unknown, and represents key information necessary to determine the need for prophylaxis. A large cross-sectional study using the National Trauma Databank was performed evaluating for the incidence and risk factors of VTE in isolated tibia fractures. The overall incidence of DVT and PE are extremely low in cases of isolated tibia fractures, which brings into doubt a role for routine use of chemical prophylaxis for these fractures.
