mild(®) Lumbar Decompression for the Treatment of Lumbar Spinal Stenosis.

More than 1.2 million people are undergoing treatment for lumbar spinal stenosis (LSS) in the United States. Yet, therapeutic options for these patients are limited to either conservative treatments or highly invasive surgeries.

Interobserver reliability of detecting lumbar intervertebral disc high-intensity zone on magnetic resonance imaging and association of high-intensity zone with pain and anular disruption.

Study Design: Retrospective analysis of a spine imaging center's records of patients with chronic low back pain referred by tertiary care facilities.

Objectives: 1) To assess the interobserver reliability of detecting lumbar intervertebral disc high-intensity zone on T2-weighted magnetic resonance imaging, and 2) to assess the relation between high-intensity zone and discography or post-computed tomography in symptomatic patients with low back pain.

Summary Of Background Data: Two of the three previous studies on this subject found an association between high-intensity zone and the presence of Grade 4 anular disruption with discographic reproduction of patients' exact low back pain.
