By Direct Motion Finger Inherence Artery Island Skin Flap To Repair Digit Tip Injury

Objective: To probe curative effect of using anterograde digital artery island flap from the same finger to repair digit tip injury.Methods: 46 cases of the digit tip injury were treated with anterograde digital artery island flap transfer from the same finger after the wound surface cleaned immediately. The defect scopes are 1.0cm×1.0cm to 2.0cm×2.5cm.The skin flap based on wound edge designs in the distal or middle section of the same finger , which longitudinal axis is the radial or ulnaris neurovascular bundle, proximal end doesn't exceed the middle finger crease,and two sides don't exceed the midline of dorsal and palmaris.The size of flaps were 1.0 cm×1.0 cm to 2.0cm×2.5 cm.Results: All the 46 transferred flaps survived completely. Postoperative follow-up ranged from 3 to 12 months, the flaps had good appearance and texture. No patients complained of pain or cold intolerance. The mean static two-point discrimination was 6mm to 10mm . According to the TAM standard, the results were excellent in 28 cases, good in 16, fair in 2, with 95% overall excellent and good rate.
