Abstract：
Very often, post-traumatic defects involve multiple tissues. Microsurgical techniques can reconstruct them with tissues taken from a toe: from the nail complex alone to compound osteo-onychocutaneous flaps. Several techniques have been reported since the 1980s. This paper describes techniques and indications for microsurgical nail reconstruction. Technique differs according to the deficit, and first and foremost whether only the nail complex is involved or whether other components of the fingertip important for the normal growth of the nail, such as the phalanx bone or the finger pad, are also missing (toenail flaps and the custom-made osteo-onychocutaneous flaps). For most patients the absence of a fingernail is an esthetic rather than functional concern, and the outcomes of microsurgical reconstruction are far from ideal in this regard. We prefer to reserve reconstruction for symptomatic patients with functional impairment.
摘要：
很多时候,创伤后缺损涉及多个组织。显微外科技术可以用从脚趾取出的组织重建它们：从单独的指甲复合体到复合骨甲皮瓣。自1980年代以来，已经报道了几种技术。本文介绍了显微外科指甲重建的技术和适应症。技术根据赤字而有所不同，首先，是否只涉及指甲复合体，或者指尖的其他成分是否对指甲的正常生长很重要，例如指骨或指垫，也缺少（趾甲皮瓣和定制的骨甲皮瓣）。对于大多数患者来说，没有指甲是一种美学而不是功能问题，在这方面，显微外科重建的结果远非理想。我们更愿意为有症状的功能障碍患者保留重建。
