Objective To evaluate the elinical effect of the use of a fi＇ee flap taken from the supra-wrist branch of the ulnar artery in the reconstruction of the extensive soft tissue defects of the hands. Methods 13 cases with extensive soft tissue defects of the hands were reconstructed with the free flap taken from supra-wrist branch of the ulnar artery. The minimum flap size was 10cm ×cm, while the maximum was 18cm×9cm. Follow up had been done for 6 months after the free flaps operation. Results All the surgical processes of 13 free flaps operatiuns were smooth and all flaps survived. During the 6 months of follow-ups after operations, the flaps were soft and wear resistant with good blood circulation, and sensation recovery of up to S3 ＋ （two-point discrimination is within the range of 5mm - 11mm）. Conclusion Free flap taken from supra-wrist branch of the ulnar artery used in the reconstruction of extensive soft tissue defects of the hands can achieve good clinical efficacy with the advantages of safety and reliability.
