We treated fingertips injured through the proximal half of the nail bed using artificial dermis in 22 patients from 2004 to 2009. We classified the injuries to the nail bed into three types according to where the wounds were. Type І was localised to the nail bed with or without minor injury to the surrounding structure; type II was an avulsion and amputation of the fingertip including the nail bed, the finger pulp, and the distal phalanx at the level of the proximal nail bed; and type III was post-traumatic shortening of the nail, in which the pulp and distal phalanx were intact. Regeneration and elongation of the nail was achieved in every patient by applying artificial dermis. All patients were satisfied with the results.
2004年至2009年期间，我们使用人工真皮治疗了22例甲床近端一半受伤的指尖。我们根据伤口位置将甲床损伤分为三种类型。I型为局限于甲床，周围结构有或无轻微损伤；II型为指尖撕脱和离断，包括甲床、指腹和近端甲床水平的远节指骨；III型为创伤后指甲缩短，其中指腹和远节指骨完整。通过应用人工真皮，每位患者的指甲均实现了再生和延长。所有患者对结果均满意。
