Methods: Between May 2012 and February 2017, 7 cases (7 fingers) with the finger nail bed central longitudinal defects were repaired with the great toenail bed flap supplied with the fibular dorsal artery of great toe. There were 3 males and 4 females; the age ranged from 17 to 35 years (mean, 27 years). The cause of injury included cutting injury in 2 cases, electric shaving injury in 3 cases, and frictional injury in 2 cases. The defect located at thumb in 3 cases, index finger in 3 cases, and middle finger in 1 case. The defect area ranged from 12 mm×8 mm to 21 mm×13 mm. The time from injury to admission was 1-2 hours (mean, 1.5 hours). The area of the great toenail bed flap ranged from 14 mm×10 mm to 23 mm×15 mm. The wound of donor site was directly sutured in 3 cases and repaired with full thickness skin graft in 4 cases.
