Figure 3. Schematic diagram of asymmetric spindle-shaped skin flap harvesting with an ultra-tension-reducing suture. (A) The skin was harvested by excision through an asymmetric spindle incision in the abdomen; (B) There were relatively few postoperative scars in the abdominal donor site after using ultra-tension-reducing suture; (C) Schematic diagram of the ultra-tension-reducing suture technique. The annotations in the picture represent the process of suturing; (D) The larger arc of the asymmetric spindle-shaped graft was utilized to reconstruct the finger web space, while the smaller arc to repair the dorsal hand.
