Successful Treatment of Chronic Ulcerative Lesion on the Heel with a Half-Width Reverse Sural Flap in a Patient Who Underwent Achilles Tendon Repair Three Years Ago: A Case Report.

A reverse sural flap is a surgical procedure to repair soft tissue defects, usually in the ankle region. This procedure involves moving a tissue flap from the calf to cover a defect in the ankle. The flap is turned 180° so that the tissue around the wound is supplied with blood by the vessels at the base of the flap, typically preserving the sural nerve and artery. This method is particularly valuable when thick and robust tissue is required to cover defects resulting from traumatic injuries, chronic wounds, or post-skin tumor removal when the local tissue is insufficient for direct closure. In this case, a patient who had undergone surgery for a chronic ulcerative lesion on the Achilles tendon three years prior to presentation at the authors' hospital was treated using a half-width reverse sural flap. Modifications to the sural flap design may be crucial considering the surgical history, blood supply, and defect size around the lower leg. In particular, previous surgeries for lower leg fractures or ligament damage may limit blood supply and require flap design modifications. [ABSTRACT FROM AUTHOR]
