Foot and Ankle Reconstruction Using Retrograde Lateral Supramalleolar Flap

<b>Background</b> Treatment of soft-tissue defects in the foot and ankle is a challenge. The use of a retrograde lateral supramalleolar flap is a promising technique for reconstruction. This study aims to assess the efficacy and outcomes of the technique. <b>Materials and Methods</b> A prospective observational study was conducted from December 2017 to December 2022. Patients with soft-tissue defects in the foot and ankle underwent reconstruction using the retrograde lateral supramalleolar flap. Data on demographics, injury details, flap dimensions, complications, and outcomes were recorded and analyzed. <b>Results</b> Forty-six flaps were used in the study. The average flap length was 17.47 cm. The maximum size of the flaps was 104 cm ² with an average of 48.43 cm ² . Venous congestion occurred in nine flaps, leading to partial necrosis in four cases. The overall success rate was 91.3%. <b>Conclusion</b> The retrograde lateral supramalleolar flap is effective in covering soft-tissue defects in the foot and ankle.
