Distal digital amputations may result in composite tissue loss, affecting both the fingertip and the nail complex. Most surgical procedures that are used for fingertip reconstruction do not restore the nail defect.
The eponychial flap is a new technique where a backward plication of the nail wall is used to expose the nail root and lengthen the visible part of the nail of the amputated digit.
The authors describe the anatomical basis and the operative technique of this flap and also review a series of 30 eponychial flaps that were performed in 28 patients. All patients presented fingertip defects treated with volar advancement flaps. This procedure was followed by an eponychial flap that restored the length of the short fingernail.
The eponychial flap procedure is an easy and reliable technique that is indicated in distal transverse digital amputations to lengthen the short injured nail. It can be associated with any method used for repairing the fingertip defect, thus enhancing the final cosmetic result of the digital reconstruction.
手指远端离断伤可能导致复合组织缺损，累及指尖和指甲复合体。大多数用于指尖重建的外科手术无法修复指甲缺损。
甲上皮瓣是一种新技术，通过将甲壁向后折叠来暴露甲根并延长离断指的可见指甲部分。
作者描述了该皮瓣的解剖学基础和手术技术，并回顾了在28例患者中实施的30例甲上皮瓣手术。所有患者均有指尖缺损，采用掌侧推进皮瓣治疗。随后进行甲上皮瓣手术，恢复了短指甲的长度。
甲上皮瓣手术是一种简单可靠的技术，适用于手指远端横行离断伤，以延长受损的短指甲。它可与任何用于修复指尖缺损的方法联合应用，从而提高手指重建的最终美容效果。
