title: Gunshot wounds below the popliteal fossa: a contemporary review.
abstract: The management of extremity injuries above the knee has been well described, but the evaluation and treatment guidelines for penetrating injuries below the popliteal crease has received less attention. A 6-year retrospective review of 100 patients who sustained isolated below-knee gunshot wounds. Patients with proximal extremity, torso, or head wounds were excluded from review so that we could focus on principles of managing below-knee wounds. All patients were evaluated with complete physical examination, ankle-brachial index, and plain X-rays. One patient presented with hemodynamic instability. Twenty-four patients underwent arteriography based on physical examination, an ankle-brachial index less than 0.9, or both. Twenty-two vascular injuries were identified in 19 patients, and an additional injury was found in a patient who went directly to surgery for pulsatile bleeding. Six of these 22 vascular injuries required treatment for bleeding or arteriovenous fistula. Treatment was by embolization in 5 and surgical ligation in 1. Thirteen patients had compartment syndromes. Thirty-five patients had fractures, and ten (29%) of these had an associated vascular injury. Four patients had peroneal nerve injuries, and three of these had long term disability. No limb loss or death occurred. We conclude that patients with low-velocity below-knee gunshot wounds sustain fractures, vascular injuries, compartment syndromes, and nerve injuries, in decreasing order of frequency. Arteriography and embolization may be useful to control bleeding; vascular reconstruction was unnecessary in our experience, and limb loss did not occur.
