title: [EFFECTIVENESS OF FREE ANASTOMOSIS CUTANEOUS NERVE DOUBLE ARTERIALIZED VENOUS FLAP GRAFT FOR REPAIRING FINGER DEFECT].
abstract: OBJECTIVE
  To explore the effectiveness of the free anastomosis cutaneous nerve double arterialized venous flap graft in repairing finger defect.
  
  
  METHODS
  Between May 2010 and May 2013, 39 patients with finger defect were treated. There were 27 males and 12 females with an average age of 31 years (range, 17-45 years). The injury to admission time was 30-90 minutes (mean, 60 minutes). The causes included mechanical injury in 23 cases, crush injury in 11 cases, and other injury in 5 cases. The thumb was involved in 13 cases, the index finger in 11 cases, the middle finger in 9 cases, the ring finger in 4 cases, and the little finger in 2 cases. Skin soft tissue defect ranged from 2 cm x 1 cm to 4 cm x 2 cm. Of them, 22 cases had tendon injury, 17 cases had tendon and phalanx injuries. The size of free anastomosis cutaneous nerve double arterialized venous flap ranged from 2.5 cm x 1.5 cm to 4.5 cm x 2.5 cm. The donor site was directly sutured.
  
  
  RESULTS
  Tension blister and swelling were observed at distal flap in 5 cases at 3-5 days after operation and were cured after symptomatic treatment; the other 34 flaps survived, and wound healed by first intention. Primary healing at donor site was obtained. The patients were followed up 6-12 months (mean, 9 months). The flap appearance and texture were good with two-point discrimination of 6-9 mm (mean, 7.5 mm). According to the upper extremity function evaluation criteria issued by the Hand Surgery Society of Chinese Medical Association, the results were excellent in 35 cases and good in 4 cases.
  
  
  CONCLUSIONS
  The free anastomosis cutaneous nerve double arterial ized venous flap not only can ensure the flap blood supply, but also can obviously improve the sensory function of the flap, which greatly reduces the risk of postoperative flap atrophy, and can achieved satisfactory effectiveness.
