Pin-site scar revision with subcisions and acellular dermal matrix

Abstract

External fixation is widely used in orthopedic and reconstructive surgery. However, it may leave retracted and depressed scars because it involves the percutaneous placement of transosseous pins or wires that are secured to an external scaffolding. These scars do not resolve or improve spontaneously, causing patients to experience dissatis-faction and possibly requiring a surgical intervention. Moreover, the management of scars that arise from external fixator pin sites is challenging because of their fibrotic and depressive features. However, by using subcisions and inserting acellular dermal matrix under the scars, the contour of the scars can be improved easily. Therefore, we present a case of pin-site scar revision using a technique that we developed.
