Rule of thumb is
- Most of the bone tumours happen in long bones (with distal femur most common, followed by proximal tibia and humerus).
- Chondroblastoma and GCT involve epiphysis.
– Chondroblastoma – humerus > lower limb bones
– GCT- can involve distal radius (which is an uncommon location)
- Spine involvement – eosinophilic granuloma (and other bone marrow bone tumours), osteoid osteoma (osteoblastoma) and osteochondroma.
- Echondrome can affect small tubular bones.
