Changes to normal structure
- Damage to periosteum:
- Invokes a hyperplastic reaction of the inner layer
- Is painful
- Exostoses can remodel or remain
- Lifting of periosteum causes new bone formation below
- Circumferential incision (e.g. during fracture)
- Longitudinal bone growth results
- May be only on one side where periosteum is damaged
- Used by surgeons to treat angular limb deformities
- Damage to periosteum:
Physis (Growth plate)
- Site of many congenital or nutritional bone diseases in the growing animal
- Open in neonates and growing animals
- Chondrocyte proliferation balances cell maturation and death
- Closes and ossifies at maturity
- Regulated by androgens
- If growth teporarily stops -> layer of bone seals the growth plate -> moves into metaphysis when growth resumes -> forms Harris lines
