Abstract:

Objective　To investigate the surgical method and efficacy of dorsal cutaneous branch-chain flaps in repairing dorsal skin defects of the finger.　Methods　Ten cases of dorsal skin defects of the finger were repaired using dorsal cutaneous branch-chain flaps, with a flap area of 1.0 cm×1.5 cm~2.0 cm× 3.0 cm.　Results　Postoperatively, only 1 case presented effusion at the distal epidermis. After drawing out effusions and wound dressing, all flaps survived. Postoperative follow-up was performed for 3~12 months. After flap repair, fingers showed good appearance. Flaps presented good appearance and color, pliability and no bloating, and all finger joints had good activity function.　Conclusion　The dorsal cutaneous branch-chain flap is characterized by stable blood supply, digital artery preservation, convenient design and simple harvest. Therefore, it is a simple and safe ideal method to repair dorsal skin defects of the finger.
