Core Tip

Core tip: This is the first report of a patient with a surgically treated os calcis lipoma, showing spectacular graft resorption at a long-term follow up. Previous studies, which report satisfactory graft performance, rely on plain radiographs for follow-up imaging and they have not used computed tomography to assess the incorporation of bone graft. The complex interplay of biomechanical and biological factors in Ward’s neutral triangle of the os calcis may account for the failure of graft integration. The possibility of bone graft resorption must be taken into account when surgical treatment is considered.
