The hook nail deformity is a relatively common complication after fingertip amputation. It can be corrected or prevented with a carefully performed surgical procedure. The nail plate is removed. The redundant nail bed that is folded over the tip of the terminal phalanx is carefully removed with an additional 2 mm that is supported by the terminal phalanx so that wound healing will not draw the nail bed over the tip of the phalanx again. The fingertip is then resurfaced by a V-Y advancement flap, with precautions taken to avoid all tension in the flap.
钩甲畸形是指尖截肢术后一种相对常见的并发症。通过精心实施的外科手术可以对其进行矫正或预防。去除指甲板。仔细切除折叠在末节指骨末端的多余甲床，并额外切除由末节指骨支撑的2毫米甲床，这样伤口愈合时就不会再次将甲床拉过指骨末端。然后通过V-Y推进皮瓣对指尖进行表面修复，并采取预防措施避免皮瓣出现任何张力。
