Background Electrical burns are one of the most devastating types of injuries, and can be characterized
by the conduction of electric current through the deeper soft tissue such as vessels,
nerves, muscles, and bones. For that reason, the extent of an electric burn is very
frequently underestimated on initial impression.
Methods From July 1999 to June 2006, we performed 15 cases of toe tissue transfer for the
reconstruction of finger defects caused by electrical burns. We performed preoperative
range of motion exercise, early excision, and coverage of the digital defect with
toe tissue transfer.
Results We obtained satisfactory results in both functional and aesthetic aspects in all
15 cases without specific complications. Static two-point discrimination results in
the transferred toe cases ranged from 8 to 11 mm, with an average of 9.5 mm. The mean
range of motion of the transferred toe was 20° to 36° in the distal interphalangeal
joint, 16° to 45° in the proximal interphalangeal joint, and 15° to 35° in the metacarpophalangeal
joint. All of the patients were relatively satisfied with the function and appearance
of their new digits.
Conclusions The strategic management of electrical injury to the hands can be both challenging
and complex. Because the optimal surgical method is free tissue transfer, maintenance
of vascular integrity among various physiological changes works as a determining factor
for the postoperative outcome following the reconstruction.
