Causes of New Periosteal Bone Formation

  1. Infection
  2. Trauma
  3. Tumor include, leukemia, neuroblastoma etc
  4. Caffey’s disease
  5. Scurvy
  6. Hypervitaminosis A

Caffey Disease

  • Infantile cortical hyperostosis
  • Characteristics
    • Febrile
    • Hyperirratibility
    • Swellin of the soft tissue
    • Cortical thickening of bone
  • Bones of jaw, forearm most affected
  • Average onset is 9 weeks
  • Rule out infection
  • Usually expectant management

Hypervitiminosis A

  • Xs leads to lysosomal rupture

Scurvy

  • Defficiency of vit C
  • Hydroxylation of proline & lysine requires Vit C as a cofactor
  • Get abnormal physis & hemorhage below the periosteum

Tumoral Calcinosis

  • Error of phosphate metabolism
  • In skeletal mature patient – phosphate restriction, consider work up of hypervitaminosis D, hyperparathyroidism, collagen vascular disease
  • Excision not always currative
