Blunt distal extremity trauma with associated distal vascular injury is more commonly involved in early limb loss and amputations. Risk factors for delayed amputation include major soft tissue injury, compartment syndrome, ischemia of more than 6 hours, and associated fracture.2 Injuries involving the lower extremities are more common than injuries involving the upper extremities. The two most commonly injured blood vessels are the femoral and popliteal vessels.3
