Combined rectus abdominis muscle/paraumbilical flap and lower abdominal flap for the treatment of type III circumferential electrical burns of the wrist

摘要

Background Type III circumferential electrical burns of the wrist are one of the most severe electrical injuries, involving rather extensive necrosis, progressive blood circulatory embarrassment and a high amputation rate. This injury poses a challenge for vascular reconstruction and wound coverage. The purpose of this study was to evaluate the effectiveness of the combined rectus abdominis muscle/paraumbilical flap and lower abdominal flap for the treatment of type III circumferential electrical burns of the wrist. Methods Six men (age, 19-32 years; average, 21 years) with type III circumferential electrical burns of the wrist were included. After thorough debridement, the volar wound was repaired with a partial rectus abdominis muscle/paraumbilical flap and the dorsal wound was repaired with a lower abdominal flap. Results Flap survival was complete in all six patients. During a follow-up of 6-12 months, the flaps showed good texture and shape. No abdominal hernia occurred in any patients. The scar on the abdominal wall was acceptable. Conclusion The combined rectus abdominis muscle/paraumbilical flap and lower abdominal flap has large wound coverage potential and offers a new, easy, safe option for the treatment of type III circumferential electrical burns of wrist.
