目的　探讨游离桡动脉腕横纹穿支皮瓣移植修复手指小面积皮肤软组织缺损的临床效果。  方法　2016年01月~2017年06月对11例手指皮肤缺损患者，缺损面积约为1.5 cm×3.0 cm～2.0 cm×4.0 cm,采用游离桡动脉腕横纹穿支皮瓣游离移植修复手指小面积皮肤缺损。  结果　术后11例皮瓣均成活，随访6~12个月，修复手指外形和功能恢复满意，皮瓣供区损伤小，瘢痕轻、仅遗留线状瘢痕，腕关节屈、伸功能无明显障碍。  结论    动脉腕横纹穿支皮瓣具有不牺牲主干血管、血供可靠、供区损伤小等优点，是修复手指小面积皮肤软组织缺损较为理想的方法。

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.
