Radiologic studies and photographs of patient 4. a T1 gadolinium-enhanced magnetic resonance images of at the first presentation demonstrate partial tumor invasion into the lateral cortex of the proximal tibia (arrow). b After allograft reconstruction, the proximal tibia was reinforced with a lateral proximal tibial plate and screws. c Radiographs show a stress fracture in the proximal tibia 5 months post-operatively. A black arrow and white arrow point a thin oblique fracture line and posterior fracture-associated callus formation, respectively
