Extremity Reconstruction Using Nonreplantable Tissue (“Spare Parts”)

After a severe digital or extremity injury, the replantation surgeon should always seek to make the best use out of what tissue is available for reconstruction. Exercising sound surgical judgment and being creative allow the surgeon to restore function to critical areas of the hand or extremity by the judicious use of available tissues that would otherwise be discarded. The use of “spare parts” should, therefore, always be considered to facilitate digital or extremity reconstruction when routine replantation is not possible or is likely to produce a poor functional result. The surgeon should always try to use available nonreplantable tissue to preserve length, obtain soft tissue coverage, or most importantly improve the function of remaining less injured digits. This article presents several case studies that illustrate the principals of spare parts reconstruction performed at the time of the initial debridement using nonreplantable tissue to provide coverage or improve function.
