ABSTRACT

Objective To explore the outcomes of free flap from the radial artery superficial palmar branch (RASP) innervated by the lateral cutaneous nerve of the forearm for repairing the defects of finger pulp. Methods From April, 2013 to February, 2015, 20 fingers in 20 cases were treated with free flap from RASP innervated by the lateral cutaneous nerve of the forearm. The area of flap was from 1.8 cm×2.0 cm to 2.0 cm×4.0 cm. Postoperative fol-low up was done termly. Results All 20 flaps survived. All cases were followed-up for 7-20 months ( averag, 12 months). The flaps appeared well with good texture. The two-point discrimination was from 7 mm to 12 mm, and grad-ed with S3 and S3+sensation. There was little scar noted at the donor site in the wrist. There was no influence of hand and wrist function. Conclusion The method of using free flap from SASP innervated by the lateral cutaneous nerve of the forearm to repair the defects of finger pulp has good clinical effect.
