Beside the nerve root nearly all lumbar structures are potential sources of LBP, such as the facet joints, the intervertebral discs, bones, fascial structures and muscles[42]. Especially facet joint osteoarthritis is known for radiating pain without evidence of nerve root compression[43,44].

If this is painful, firm pressure is then applied to the popliteal fossa. Pain in the lumbar region or radiculopathy is a + sign for nerve root compression. The test is commonly linked to L4/L5 radiculopathy. *** *** Femoral Nerve Traction Test (not included in the regional sheet) = Assessment for mid-lumbar nerve root involvement (L2-L4).

References: Description Inflammation of a nerve root in the lumbar region of the spine due to compression by an extruding disk. Pathology (organ, cell, system) Grossly, cracks develop in the disc, which shrinks and buckles out. There is narrowing of the disc space.
Sciatica L4
Unilateral disc herniation between L4 & L5 results in compression of L5 nerve root. L5 nerve root compression : Motor weakness : Extensor hallucis longus, Gluteus medius muscle, extensor digitorum longus and brevis. Reflex : Usually none, diminished tibialis posterior reflex which is difficult to elicit.

Compression can affect distal nerve segments, as in tarsal tunnel syndrome or peroneal neuropathy at the fibular neck, but is even more common proximally where a herniated disc may compress a spinal nerve root. In its most mild form, compression may be intermittent due to positioning, with associated reversible ischemia of the nerve.
