Injury due to high-voltage (>1000 V) electricity is one of the most challenging problems in emergency medicine and plastic surgery. Extremity amputation because of electrical injury yields a stump that leaves vital structures, such as bone, muscle, blood vessels, and nerves, exposed; these structures should be covered with appropriate tissue. We designed a retrospective study that included twelve patients with a high-voltage electrical injury followed by trans-humeral amputation who were evaluated between 2004 and 2013. The ages of the patients ranged between 8 and 35 years (mean, 16.9 years). Following amputation, the defects were covered with an ipsilateral pedicled latissimus dorsi (LD) myocutaneous flap for stump protection and functional transfer.
