Q

What is the 3 column concept for thoracic/lumbar spine trauma?

A
  • If two or more columns are disrupted, then it is considered an unstable injury
  • If the middle column is disrupted it is considered aunstable injury

(Anterior Column = ALL, anterior 2/3rds of vertebral body and disc

Middle Column = PLL posterior 1/3rd of vertebral body and disc

Posterior Column = Posterior arch, all other posterior ligaments)
