Non-structural pathology is defined as findings that are based on the following:
- Possibly or probably normal for the patient’s age and activity
- Based solely on a subjective test (interpretation of your reponse to a painful stimulus)
- Non-progressive spinal deformities
- Clinical picture is vague and there is not a definite match of pain to the pathology.
- Examples are:
- Dehydrated discs on MRI-just means there is less water and stiffer
- Facet pain based just on facet blocks
- Discogenic pain based on discography (not a valid test)
- Old compression fractures that have healed
- Stable degenerative spondylolithesis with just back pain
- Stable isthmic spondylolithesis with just back pain
- Non-progressive degenerative or idiopathic scoliosis
- Right now this is a suggested starting point. There is legitimate debate on many of these diagnoses regarding whether they are structural or not. The ones I feel are the most up for debate are:
- Degenerated discs with Modic changes (bony reaction)
- Non-progressive degenerative scoliosis—the absolute number of degrees that a scoliotic curve should be fused for pain is not defined.
