ABSTRACT
Objective@#To explore the clinical effect of the flap from the rasceta area to repair the hand wound, with relayed superior carpal perforator flap of the ulnar artery to repair the donor site.@*Methods@#During July 2015 to July 2016, 11 cases of hand skin and soft tissue defects from 3.0 cm × 5.5 cm to 5.0 cm × 7.5 cm were treated. and the rasceta flap was used to repair the wound. The superior carpal perforator flap of ulnar artery was used to repair the donor site.@*Results@#All the 22 flaps survived after operation in 11 cases.Followed up for 6-12 months (average 8.5 months). The area of the superior carpal branch of ulnar artery skin flap is 4.0 cm ×6.5 cm to 6.5 cm× 8.5 cm. The skin flap appearance was good and the scar of the donor area was minimal. After 6 months of operation, the function of the affected limbs was evaluated according to the criteria of functional evaluation of the upper limb of the Chinese Medical Association, 8 cases were excellent, 3 were good, and the excellent rate was 88.9%.@*Conclusions@#Relayed superior carpal perforator flap of ulnar artery. Not only expands the repair area of the island flap, but also avoids the skin grafting in donor site. It is applicable to the recovery of the function and appearance of the affected limbs.
