vein thrombosis, knee trauma, bone fractures


Objective: To report the incidence between Deep Vein Thrombosis (DVT) in ipsilateral femur and tibia fractures (floating knee), considering its relation with hospitalization time, fracture classification, treatment implemented and comorbidities.

Methods: This is a retrospective observational analytical study using the medical charts of thirty patients admitted with floating knee to a trauma hospital between October 2016 and July 2017.

Results: Of the 30 patients assessed, 25 (83%) were men and 5 (17%) women. The most affected age range was between 21 and 30 years (36%). The dominant limb was affected in 17 (57%) patients. A total of 19 (63%) patients were classified as Fraser type I, 18 (60%) had open (compound) fractures, 16 (53%) fractures of the tibia and 8 (26%) of the femur. The most widely used emergency treatment was external fixation of the femur and tibia (25 patients = 83%). Seven patients used a femur plate and external fixator in the tibia as definitive treatment. Of the 30 patients studied, 14 (46%) suffered infectious complications, 9 (30%) superficial and 5 (16%) deep. Deep venous thrombosis was observed in 17% of patients (p=0.409). 

Conclusion: Despite the use of antithrombotic prophylaxis, there was a high incidence of DVT in the affected limb of patients with floating knee. Fraser I fractures, being male and the non-dominant limb increases the likelihood of developing DVT.
