Since 1985, 76 pedicled island flaps had been used for primary repair of skin defect of thumb and 62 flaps for reconstruction of thumb. Fifteen thumbs were reconstructed by 29 pedicled island flaps in which 14 from dorsum of middle phalanx of index and middle fingers, 12 reversed island flaps from forearm and 3 from dorsum of proximal phalanx of index fingers. Eight degloved injuries of thumbs were repaired by 8 reversed island flaps from forearm. Thirty-nine skin defects of thumbs were treated by pedicled island flaps in which 16 from dorsum of proximal phalanx of index finger and 23 from dorsum of middle phalanx of index and middle fingers.All of pedicled island flaps survived excep onw flap had partial neerosis and two had slight infection. The apperance and function of the thumbs were satisfactory. In this paper, the adventages of pedicled island flaps in repairing thumb injuries were introduced and the points required attention during the operation were also discussed.
