Malignant foot tumours are often treated with amputations due to anatomical difficulties. Limb salvage techniques are difficult to perform, as a stable, sensible and plantigrade foot should be obtained to prevent further problems. In this report, we present a midfoot reconstruction with a vascularized free fibula, osteomized in a V-shape after wide resection of a midfoot synovial sarcoma. We describe the reconstruction of both longitudinal arches in which using a vascularized autograft facilitated union, remodeling of the bone, and obtaining a functional foot
