Abstract: Objective To discuss the clinical outcome of the modified super large dorsal metacarpal artery flap in reconstruction of circumferential fingertip avulsion. Methods Twenty-four patients with circumferential fingertip avulsion were treated by the modified super large dorsal metacarpal artery flap from January 2004 to August 2008. There were six index fingers, 11 middle fingers, five ring fingers and two little fingers with surface defects beyond the distal interphalangeal joint and the distal degloving length ranged from 0.8 cm to 3.1 cm. Emergency operation was performed on 22 fingers and stage Ⅱ surgery was done for distal skin necrosis of two fingers. Results Twenty-one patients with 21 fingers were followed up for 6-28 months, which showed that all flaps survived, with satisfactory appearance and function, and that the point discrimination of flap was for 6-9 mm ( average 7.6 mm). Conclusion Modified super large dorsal metacarpal artery flap is an ideal method for reconstruction of the circumferential fingertip avulsion with advantages of easiness, convenience and short treatment period.
