Zusammenfassung: | Introduction. Complex wounds of the hand often result in soft tissue defects that are not amenable to primary closure, vacuum-assisted closure, or tissue expansion. Injuries presenting with large defects involving multiple levels of tissue must be addressed by using techniques at higher rungs on the reconstructive ladder, such as split-thickness grafting, pedicled flaps, or free flaps. When repairing palmar tissue, these techniques fall short due to their failure to approximate structure and function of specialized skin. More recently, dermal substitutes containing a decellularized extracellular matrix (ECM) have been used in reconstruction of soft tissue defects, acting as a structural scaffold for the regrowth of native cells. Extracellular matrix products have been shown to improve functional and sensory outcomes in areas requiring highly specialized skin. Urinary bladder matrix (UBM), a porcine ECM scaffold, is unique in that it contains an intact epithelial basement membrane that promotes more organized regrowth through layered structure. Case Report. This case presents a novel use of this product in resurfacing 80% of a palm after postoperative necrosis following a table saw injury to the right volar palm at the distal crease. The patient had intact sensation and near normal functional outcomes at most recent follow up. Conclusions. The UBM may be a valuable adjunct to achieve soft tissue coverage in large, complex hand wounds, particularly those involving the palmar surfaces. |
