Figure 4. (A) The preoperative dorsal thumb defect with the extensor pollicis tendon exposed. (B) The defect was debrided and washed out properly, and the Brunelli flap and pedicle were designed and marked. (C) The flap was raised, taking into account that the most distal extension of dissection should be proximal to the interphalangeal joint. (D) Flap was inset with a good postoperative result.
