Clinical application of neurocutaneous vascular flap on dorsal part of hand or finger in repair of distal finger injury

Objective To introduce the clinical application of neurocutaneous vascular flap on dorsal part of hand or finger for the soft tissue defect of the distal finger. Methods According to different defect sites of fingertip soft tissue, 56 flaps of 3 different kinds were devised to repair them : dorsal neurocutaneous vascular flap of the second or third metacarpal for the thumb, ulnar dorsal neurocutaneous vascular us flap of the thumb for the index, dorsal neurocutaneous vascular flap of the finger for the third to fifth finger. The largest flap was 2.1 cm×3.3 cm. Results Fifty-six flaps survived completely. The period of follow-up ranged from 6 months to 3 years. The contour and consistency of the flaps were nearly normal. Two-point discrimination was 5.4-9.6 mm. The appearance and function were satisfactory.. Conclusion The neurocutaneous vascular flap on dorsal part of hand or finger is a good flap for coverage of soft tissue defects of the distal finger.
