Low back pain — structured viva
Structured oral on low back pain: defending no-imaging with trial data, dismantling paracetamol and steroid habits with PACE and Goldberg, the opioid nulls, stratifying chronicity risk with STarT Back, selling cognitive functional therapy, and proving you know what cauda equina timing evidence actually shows.

Prompt
The examiner opens: 'Your patient wants a back MRI and a box of oxycodone — talk me through why you'll refuse both.' The viva branches through imaging evidence, drug-trial honesty, risk stratification, chronic-pain management and the emergency that must never be missed.
Stem
You are the GP. A 46-year-old with two weeks of nonspecific low back pain demands an MRI and strong painkillers, saying his cousin "had his spine fixed by surgery". [1]
