[One patient with chronic refractory wound caused by bamboo sticks in lower leg]

One patient with chronic refractory wound in right lower leg was admitted to our department in June 2017, which experienced repeated ulceration for 4 years. On 4 days post admission, two bamboo sticks were taken out from the deep muscle of the right lower leg. The wound was repaired by perforator flap of posterior tibial artery in the right lower leg. The donor site was covered with split-thickness skin in the upper leg of the same side. On 7 days post operation, the flap and skin graft survived. During follow-up of 12 months, the flap had good appearance. This case suggests that the first thing for the treatment of chronic refractory wound is to find out the cause of wound.
