C. Stenosis 1. In central lumber stenosis, with circumferential compression of the cauda equina, the associated clinical syndrome is one of neurogenic claudication. Patients note unilateral or bilateral lower extremity pain related to activity. When patients sit, they are pain-free. A key differential point between neurogenic and 2.
Conservative treatment revolves around epidural therapy, and flexion exercises.

The lumbar and thoracolumbar regions are most commonly involved, due to the arrangement of Batson's valveless vertebral plexus. Harrington has described a classification system for metastatic disease of the spine, which is useful for diagnostic and prognostic reasons. Infectious processes generally provoke enough destruction of the spinal structures to generate low back pain, but on occasion, instability, deformity, and neurologic compromise results.
