- cortical splitting and new periostitis
-
sickle cell disease
/thalassaemia/ thalassaemia /Gaucher disease -
chronic osteomyelitis
ee.g. congenital syphilis, TB - scurvy
-
sickle cell disease
- Caffey disease (infantile cortical hyperostosis)
- abnormal bone metabolism
- disordered bone growth
- heavy metal poisoning (bismuth, lead, thorium)
- hypervitaminosis D
- Thorotrast (ghost vertebrae)
-
ionising radiation
- radiation injury
- radiotherapy
- subcortical osteopenia
- leukaemia, metastases
- complex regional pain syndrome (Sudeck atrophy)
- idiopathic juvenile osteoporosis
- oxalosis (intraosseous crystal deposition)
- iatrogenic
- bone graft, subcortical bone cement
- bisphosphonates
- radiotherapy
- bone healing
- artifact
