Trans-digit Salvage Replantation Using Part of an Amputated Digit for Reconstruction of Thumb Pulp

重建外傷性手指腹面組織缺損包括植皮，局部，區域，遠端以及游離皮瓣。而且日常行醫過程中，經常會遭遇此類問題。因為手指皮膚具有耐磨等異於身體他處的特性，所以如何選擇重建方式成為整形外科醫師常見的課題，平時腳趾或足底部的皮瓣移植為提供此種獨一無二皮膚特性的方法之一，但代價是會造成另一處的外觀變形，在多處手部外傷的病人中，我們可利用無法再行顯微接回的組織來覆蓋其他部分的外傷處。我們報告一個病人同時有左手大拇指及小指的外傷，其中小指為撕脫性截肢，無法接回，因此我們將小指部份壞死的部份切除並將剩餘部位分離成脫骨性皮瓣，將此皮瓣以顯微接合血管及神經後覆蓋於拇指缺損處，於術後及門診追綜均發現皮瓣存活情形良好，此運用“備用部份”的方法提供我們作為類似的手部外傷重建的考慮之一。

Hand trauma is a common problem in daily practice. Restoration of hand function is important, especially for the pulp defect. Pulp defect can be reconstructed by many methods. However, every method has some limitations and drawbacks, like donor site deformity and morbidity. It is common for hand trauma to have multiple fingers involvement. The option of the treatments depends on the extent of tissue damage. For the non-replantable amputated finger, the residual viable tissue of the amputated part can be used for other finger defect reconstruction. We reported a patient having left hand crush injury with small finger avulsion amputation at the level of metacarpophalangeal joint and thumb pulp defect. A fillet flap was harvested from the non-replantable small finger to reconstruct the pulp defect of thumb. At one-year of follow-up, good functional result and aesthetic appearance were archived.
