Incidence of bleeding low unless on anticoagulation

Lateral compression injury

- pubic rami fracture

II Closed

A Supraclavicular

- Postganglionic / Rupture of Trunks

B Infraclavicular

- cords & branches

C. Post anaesthetic

III Radiation / Other

Most common site for skeletal TB

- usually haematogenous spread

- can be direct from lung

2. Central - high incidence of vertebral collapse

3. Anterior - instability less common with less bony destruction

Affects multiple contiguous vertebrae
