Answer

See the list below:

  • Histologic changes demonstrate that vertebral growth endplate cartilage is abnormal, with a decreased collagen/proteoglycan ratio on electron microscopic examination.

  • Enchondral ossification is altered profoundly in affected segments, and there are increased proteoglycan levels.

  • The matrix of the endplates is abnormal, thus interfering with normal vertebral growth.
