Thromboembolic Disease After Orthopedic Trauma

Abstract

Orthopedic trauma results in systemic physiologic changes that predispose patients to venous thromboembolism (VTE). In the absence of prophylaxis, VTE incidence may be as high as 60%. Mechanical and pharmacologic thromboprophylaxis are effective in decreasing rates of VTE. Combined mechanical and pharmacologic thromboprophylaxis is more efficacious for decreasing VTE incidence than either regimen independently. If pharmacologic thromboprophylaxis is contraindicated, mechanical prophylaxis should be used. Patients with isolated lower extremity fractures who are ambulatory, or those with isolated upper extremity trauma, do not require pharmacologic prophylaxis in the absence of other VTE risk factors.
