[Repair of skin and soft tissue defects at distal end of finger with serrated flap with digital proper artery and nerve pedicle combined with bilaterally pedicled V-Y advancement flap of the injured finger].
OBJECTIVE
To investigate the therapeutic effects of repair of skin and soft tissue defects at distal end of finger with serrated flap with digital proper artery and nerve pedicle combined with bilaterally pedicled V-Y advancement flap of the injured finger.


METHODS
Thirteen patients with skin and soft tissue defects at distal end of 13 fingers were hospitalized from September 2013 to January 2015. After debridement, the wound area of finger ranged from 1.2 cm × 0.8 cm to 1.8 cm × 1.5 cm. Serrated flap with digital proper artery and nerve pedicle combined with bilaterally pedicled V-Y advancement flap of the injured finger were used to repair the defect. The flaps were interruptedly sutured. The areas of bilaterally pedicled V-Y advancement flap and serrated flap with digital proper artery and nerve pedicle ranged from 0.52 to 1.11 and 2.60 to 5.23 cm(2,) respectively.


RESULTS
All flaps of 13 patients survived completely. The patients were followed up for 6 to 24 months. The color and texture of the flaps were good. After reconstruction, the finger tips were in round in shape. The appearance of the fingers was consistent with that of the normal fingers, and joint motility was normal. No hook-nail deformity or knuckle dysfunction was found. Sensation of the flaps was estimated as S4, and the distance of two-point discrimination ranged from 2 to 3 mm. The recovery of the joint motion function of the fingers was excellent.


CONCLUSIONS
Serrated flap with digital proper artery and nerve pedicle, combined with bilaterally pedicled V-Y advancement flap from the injured finger can repair the skin and soft tissue defects at distal end of finger with reliable blood supply and simple operative technic. It also could avoid the formation of deformity subsequent to a linear scar, and a satisfactory appearance with good function could be obtained.
