Lumbar disc compression collapse refers to a significant loss of intervertebral disc height and integrity, resulting in collapse of the disc space and ...

Lumbar disc compression collapse at the L1–L2 level occurs when the intervertebral disc—a soft, cushion-like structure between the first and second lumbar ...

Lumbar disc compression collapse is a pathological condition in which one or more intervertebral discs in the lumbar (lower back) region lose height and ...

Terminal spinal cord compression refers to any pathological process that exerts pressure on the conus medullaris—the distal, tapered end of the spinal cord ...

Spinal cord compression at the L5–S1 level occurs when structures surrounding or within the spinal canal press on the cauda equina nerve roots or the conus ...

Spinal cord compression at the fourth and fifth lumbar vertebral levels (L4–L5) occurs when structures within the spinal canal press on the nerve roots or the ...
