Radiographic imaging of the femoral shaft in anterior-posterior and lateral views showing a massive irregular periosteal hypertrophic lamellar ossification at with an irregular sunburst pattern as well as the appearance of spiculae. Furthermore the radiographs show the condition of intramedullary nailing for a tibial shaft fracture years ago.
