How long does a T12 fracture in my back heal? 15 yrs old boy athletic drink lot of calcium?

It says in my doent from doctors: There is slight depression of the anterior aspect of the vertebral body noted at T12 level and may suggest slight compression fracture. This should be correlated if there is any history of clinical symptoms over this site. The rest of the vertebra show normal heights. Vertebral alignments seem to be maintained. Evaluation of lumbosacral spine also shows normal vertebral heights and alignments. The disc spaces are maintained throughout the thoracic and lumbosacral spine.
