PurposeThe purpose of this study is to compare the major amputation rate following two different fasciotomy techniques, conventional versus straight midline, in patients with high-voltage arc burn injury by electric currents of 22,900V to the upper extremities.MethodsA retrospective analysis of 230 patients (270 burned upper limbs) who underwent fasciotomy after high-voltage electrical injuries between 1996 and 2007 was performed. The patients were divided into two groups according to the fasciotomy method used. From 1996 to 2002, 158 patients (184 limbs) underwent conventional fasciotomy by Green's volar-ulnar incision (conventional fasciotomy group). From 2003 to 2007, 72 patients (86 limbs) underwent fasciotomy using a straight midline curved incision (midline fasciotomy group). The patients were also divided into two groups based on whether the fasciotomy procedure was performed early or late. Patients who underwent fasciotomies <8h after injury were classified as early, while those who underwent it >8h after injury were classified as late. Major amputation rates were compared between two fasciotomy methods and analyzed following fasciotomy timing.ResultsThe midline fasciotomy group had a significantly lower major amputation rate (33.7%) than the conventional fasciotomy group (59.2%) (p<0.001). A subsequently decreased major amputation rate of 27.8% was observed in the early fasciotomy subgroup of the midline fasciotomy group (p=0.025).ConclusionEarly fasciotomy remarkably reduced the major amputation rate after high-voltage arc injury; in the setting of minimized vascular exposure after fasciotomy, a midline straight incision could ensure that various types of reconstructive microsurgical procedures and primary skin closures can be used to save limbs.
