Popis: Objective: The objective of this study was to evaluate and compare the effect of 2 reverse pedicle flaps for repairing soft tissue defects of the finger. Methods: In this prospective study, 46 patients with finger soft tissue defects planned for flap repair of soft tissue were enrolled from April 2011 to March 2015, and randomized to undergo either repair of reversed island flap pedicled on a perforating branch of the dorsal metacarpal artery in group A (25 cases) or retrograde island flap of dorsal branch of the proper digital artery in group B (21 cases). The survive rate, hand function, postoperative complications, and appearance were compared between the 2 groups. Results: Patients were followed up for an average of 18 months in group A while 15 months in group B. All flaps in both groups survived, with satisfactory sensory function. The 2-point discrimination testing of group A was from 6.0 to 9.0 mm (7.1 ± 0.5 mm) while it was from 4.0 to 7.0 mm (5.2 ± 0.4 mm) in group B, significantly superior to that of group A ( P < .05). Motion of finger interphalangeal joint in both groups was not significantly different, nor was affected in comparison with the healthy side. As for complications, 2 cases of early venous congestion and 2 cases of superficial skin necrosis occurred in group A while 1 case of flap blister occurred in group B. In addition, we observed that the appearance of the flap was 5mm higher than normal skin in 5 cases in group A, while only in one case in group B. The difference was significative ( P < .05). Conclusion: Both reverse pedicle flaps were safe and reliable for repairing finger defects, while in consideration of sensory function and appearance, retrograde island flap of dorsal branch of the proper digital artery may suit better in fingertip defects repair than reversed island flap pedicled on a perforating branch of the dorsal metacarpal artery.
