Objective　To explore the clinical therapeutic effect of  transverse wrist crease perforator flaps repairing small-sized soft tissues defects of the fingers.　Methods　From January 2016 to June 2017, 11 cases of small-sized soft tissue defects of the fingers, ranging from 1.5cm×3.0cm to 2.0cm×4.0cm,  were treated with transverse wrist crease perforator flaps.　Results　All patients were followed up  about 6 to 12 months, and all of the flaps survived. The flaps possessed soft texture without bulky appearance. The repaired fingers gained satisfactory recovery of both appearance and function. Donor site morbidity was minor, with only linear scar formation. The flexion and extension function of the wrist was not hindered. 　Conclusion　The transverse wrist crease perforator flap has the advantages involving of protecting the main vessel, reliable blood supply, high survival rate and minor donor site morbidity, which is an ideal option for repairing small soft tissue defects in fingers.
