PURPOSE
This study aimed to describe the reverse digital artery cross-finger flap (RDAC flap) in the treatment of failed finger replantation.
METHODS
This study retrospectively reviewed the records of patients who underwent modified RDAC flap reconstructions for failed finger replantation and assessed their outcomes. Of the patients who underwent soft tissue reconstructions for finger injuries between March 2011 and February 2015, we enrolled 11 patients in whom RDAC flap reconstruction procedures were performed to treat the failed replantations.
RESULTS
The flaps survived in all cases, with a mean static, two-point discrimination value of 5.3 mm (range, 4-7 mm) in the healed flaps. The sizes of the flaps ranged from 2 × 1 cm to 2.3 × 1.5 cm.
CONCLUSION
The RDAC flap was introduced by Lai et al., and it is a mixed form with the advantages of both cross-finger flap and heterodigital island flap. Our results suggest that it could provide reliable coverage of the sensate soft tissue of fingers with failed replantation.
目的
本研究旨在描述逆行指动脉交指皮瓣（RDAC皮瓣）在治疗断指再植失败中的应用。
方法
本研究回顾性分析了接受改良RDAC皮瓣重建术治疗断指再植失败患者的病历，并评估其治疗效果。在2011年3月至2015年2月期间因手指损伤接受软组织重建的患者中，我们纳入了11例行RDAC皮瓣重建术治疗断指再植失败的患者。
结果
所有皮瓣均存活，愈合皮瓣的平均静态两点辨别觉值为5.3毫米（范围为4 - 7毫米）。皮瓣大小从2×1厘米至2.3×1.5厘米不等。
结论
RDAC皮瓣由Lai等人提出，它是一种兼具交指皮瓣和异指岛状皮瓣优点的混合形式。我们的结果表明，它可为断指再植失败的手指提供可靠的感觉性软组织覆盖。
