Abstract
INTRODUCTION: This study demonstrates the use of a modified free innervated DRAP flap utilizing the supermicrosurgery technique for fingertip reconstruction.
MATERIALS AND METHODS: From January 2010 to February 2014, 20 cases of fingertip reconstruction were performed using a short pedicle mini innervated transverse DRAP flap. The patients demographics, the mechanism of injury, the defect size and anatomical location, the source of pedicle vessels, the recipient vessels, the nerve branch used for innervation, the follow-up and sensation outcomes are reported. Three cases are presented demonstrating different anatomical fingertip injury reconstructions.
RESULTS: 20 consecutive traumatic fingertip injuries (M:F-14:6) were reconstructed with a free DRAP flap from the same hand. 6 index, 6 middle, 5 ring and 3 little finger defects were included in this study. All procedures were performed under regional anaesthesia and sedation. There were no intra- or post-operative complications. The average operative time was 105 (85-120) minutes. Each flap size was matching the size of the defects. All donor sites achieved primary closure and good cosmesis. The average follow-up was 12.8 (6-28) months. Follow-up demonstrated a static two-point discrimination of the flaps with an average distance of 5.5 (4-7) mm.
CONCLUSION: The innervated DRAP flap has proven to be an easy, reliable and effective sensate fingertip reconstruction option, utilizing the supermicrosurgery technique.
LEVEL OF EVIDENCE: Level IV, retrospective series.
