Radiographic control 4 weeks after injury (Figure 4(a)) showed signs of healing, and the patient was advised to start performing range of motion (ROM) exercises in order for ankle stiffness to be avoided. New X-rays, 8 weeks after injury (Figure 4(b)), revealed callus formation at the fracture site. At his last followup 18 months (Figure 4(c)) after injury, he was painlessly ambulatory with no restriction to his ankle or foot ROM although there were no signs of mineralization in the cystic lesion.
