Purpose: The reconstruction of posttraumatic fingertip defects requires adequate soft tissue coverage, sensibility and minimal donor site morbidity. Reconstruction is more difficult in the case of multiple fingertip defects. The purpose of this study was to report the results of reconstruction of multiple fingertip defects using the innervated radial artery superficial palmar branch perforator flap (iRASP).
Methods: We performed 19 cases of the iRASP for the reconstruction of multiple fingertip defects. The surgery was performed in two stages. In the first stage, defects were covered with the iRASP. In the second stage, the flap was divided 2-3 weeks after the first operation.
Results: All flaps survived. At the last follow-up, static two-point discrimination was measured. A mean of 7.6 mm (6-9 mm) was measured on the affected side and 3.6 mm (2-5 mm) on the contralateral side. The sensory examination was performed at a mean 6.8 months (4-11 months) after surgery. Postoperatively, some patients complained of pain in the donor scars, but most of them disappeared after six months. Debulking surgery was not needed to improve the contours.
Conclusion: We reconstructed multiple fingertip defects using the iRASP, and obtained satisfactory functional and cosmetic results. Four fingertip defects could be reconstructed with one flap and with satisfactory sensory recovery. Therefore, the iRASP is considered an appropriate treatment for reconstruction of multiple fingertip defects.
