Third Toe Pulp Reconstruction Using the Contralateral Second Toe Hemi-pulp Free Flap

Summary: A hemi-pulp flap is widely known as a flap useful for aesthetic and functional reconstruction of the fingers, and rarely used for toe reconstruction. We performed third toe pulp reconstruction using a free hemi-pulp flap harvested from the contralateral second toe to repair the tissue defect following toe replantation. An 18-year-old woman was injured with complete left third toe amputation and open fracture of the proximal phalanx of the left second toe in a traffic accident. On the same day, third toe replantation was urgently performed. After surgery, the third toe was partially taken, and had a toe pulp tissue defect due to necrosis. It was reconstructed with a free hemi-pulp flap prepared from the contralateral second toe. The flap was completely taken. Three years after surgery, the reconstructed left third toe was aesthetically favorable. Perception of the flap region was restored up to S2 without pain and there was no complication such as numbness, callus, and ulceration. In the flap donor site (right second toe), the skin graft was unnoticeable without pigmentation. Toe pulp reconstruction requires a sensory flap as low-invasive as possible with excellent sensory restoration, texture, feel, and shear property. This method is considered as one of the low-invasive, aesthetic, and functional reconstruction methods.
