- disc degeneration
What 5 pathoanatomical issues can cause lumbar pain? What percent from each issue?
- disc (40%)
- facet (5-60% if part of OA)
- sprain
- strain
- fracture
Direction of disc herniation is (same/opposite) direction of the load?
Opposite
What is the key clinical predictor of discogenic pain?
Pain centralization
+LR 2.1-9.4
What four structural changes are related to facet syndrome?
- OA

- Overlapping territories (nondermatomal)
- To the front and back of leg
- Sometimes as far as the foot
- Referred pain may not be contiguous
- Referred pain from facets and discs overlap
How is a facet block performed?
Fluoroscopic guidance, intra-articular joint space in injected with corticosteroids and local anesthetic & contrast medium
- first injection with with short acting anesthetic (lidocaine) and the patient records duration of pain relief in a diary
- second injection 1-2 weeks later, longer lasting (bupivacaine) and the patient again charts pain relief in a diary
- diagnose if >80% pain relief
- third block can performed with saline (placebo)
If any indicators or abnormalities are present with muscle testing you should then
Use repetitive and sustained muscle testing
To see how they fatigue (how quickly)
