ABSTRACT
Objective@#To investigate the application and clinical efficacy of dorsal finger flap on repairing donor site of the digital artery perforator flap.@*Methods@#From July 2015 to February 2017, the reversed digital artery perforator flaps were used to repair soft tissue defects at distal part of the fingers. Donor site defects were reconstructed with the dorsal finger flaps in 21 fingers of 18 cases.Male 11 cases, female 7 cases. The defect areas of donor sites were about 1.4 cm×2.0 cm-1.8 cm×2.5 cm.@*Results@#Primary wound healing were achieved in 21 finger of 18 cases. All the flaps survived.19 fingers of 16 cases were follow-up for 6 to 18 months(average 9.2 months), while 2 cases were lost to follow-up.The results of hand function were excellent 14 fingers, good 4 fingers, bad 1 finger. The sensory evaluation of the digital artery perforator flap were 3 fingers S3, 14 fingers S4 and 2 fingers S5, and the distance between two points of flap was 5-9 mm.@*Conclusions@#Using proximal dorsal transverse flaps to reconstruct the defects of digital artery perforator flap can avoid skin graft.It is an effective method for the treatment of the skin and soft tissue defects of the dorsal fingers.
