A<unk>  is a semicircular skin<unk>  that is rotated into the defect on a fulcrum point.<unk> s provide the ability to mobilize large areas of tissue with a wide vascular base for reconstruction. The<unk>  must be adequately large, and a large base is necessary if a back-cut will be needed to lengthen the<unk> . If the<unk>  is too small, the residual defect can be covered by mobilizing the surrounding tissue. A drawback of<unk> s is the extended cutting and undermining needed to create the<unk> , thus increasing the risk of hemorrhage and nerve damage. This term is often used in contrast with the term "free<unk> " where the transferred tissue is completely detached.
