Figure 1 Magnetic resonance imaging examinations. A: T1WI of magnetic resonance imaging shows tumor does not involve the epiphysis; B: Epiphyseal distraction was performed to separate the epiphysis and diaphysis at a rate of 1 mm/d; C: The success of epiphysis separation was confirmed by plain x-ray 3 wk after distraction.
