Surgical Indications (Hard)
• Decompression of nerves
• Stabilisation of instability

Surgical Indications (Soft)
• Non-radicular Pain - removal of potential pain generators

Interpreting radiology
• We have no gold standard scan for pain
• Dynamic imaging (erect X-rays)
• Cross sectional imaging (CT & MRI)
• Nuclear medicine studies

Interpreting radiology
• Radiologist (by their nature) do not have the patient in front of them - they cannot correlate potentially pathological findings with actual pathology
• Degenerative changes are common to universal
