Answer

Deossification due to marrow hyperplasia can bring about the following changes in bone:

  • Decreased density of the skull
  • Decreased thickness of outer tble of skull due to widening of diploe
  • Hair on-end striations of the calvaria
  • Osteoporosis sometimes leading to biconcave vertebrae, coarsening of trabeculae in long and flat bones, and pathologic fractures
