title: Combined orthopedic and vascular lower extremity injuries: sequence of care and outcomes.
abstract: Combined vascular and orthopedic injuries requiring repair are rare. However, these injuries have a high amputation rate and significant morbidity. In a retrospective review of lower extremity injuries managed at a level I trauma center over 9 years, we identified 26 patients with combined vascular and orthopedic injuries. We evaluated their rates of amputation and revascularization procedures based on sequence of care and initial intervention. Patients were stratified into 3 groups based on the initial intervention given: definitive vascular repair (n = 17), orthopedic stabilization (n = 4), and temporary shunt (n = 5). Amputation rates were 29% (5/17) in the vascular group and 20% (1/5) in the shunt group; there were no amputations in the orthopedic group (0/4). Revascularization rates were 41% (7/17), 25% (1/4), and 20% (1/5) in the vascular, orthopedic, and shunt group, respectively. Mangled Extremity Severity Scores higher than 6 had an overall relative risk of 5.5 for amputation (P<.05). We conclude that temporary vascular shunting followed by orthopedic stabilization and then definitive vascular repair is the most reasonable sequence of care for minimizing rates of amputation and revascularization procedures in this cohort of patients.
