Hand V-Y Flap Surgery

The main point of surgery for the VY flap is to cut the fiber bundle and the ligament, so that the skin on the palm side has sufficient mobility without damaging the finger vascular bundle. Treating diseases: refers to deformed multi-finger malformations Indication 1 Wound repair of the distal segment II degree finger (a broken finger of the distal phalanx). 2 Finger skin on the back side or nail bed defect. Contraindications 1. Patients with systemic diseases who cannot tolerate surgery. 2. There are local infections in the surgical area. Preoperative preparation 1. Injection of tetanus antitoxin. 2. Prophylactic antibiotics. Surgical procedure Take the volar middle VY flap as an example: (1) Cut the skin of the volar V-shaped flap. The dermis layer was cut at both sides of the neurovascular bundle. Under the dermis layer, the proximal nerve fiber bundle is freed to the proximal end by 1 to 2 cm. (2) In addition to the above-mentioned soft tissue retention associated with the finger neurovascular bundle, other fibrous septa and soft tissue should be cut at the palmar surface of the phalanx. (3) The above two steps should be carried out under the tourniquet to stop bleeding. The tourniquet should be relaxed after the V-shaped flap is free. (4) The V-shaped flap with good blood circulation was displaced to the stump, and the bottom edge was sutured with the dorsal edge or the margin of the stump, and the lateral edge of the flap was sutured with the lateral edge of the stump. (5) The scapular donor area is directly sutured, and the final stump is sutured into a Y shape.
