Lumbar Disc Compression Collapse at L5–S1

Anatomically, the L5–S1 disc bears the greatest mechanical stress in the lumbar spine? due to its location at the lumbosacral junction, where lordotic curvature and axial load converge. The disc’s vascular supply is limited to peripheral endplate diffusion, making it particularly susceptible to nutritional insufficiency and early degeneration. Over time, endplate microfractures and Modic changes (type I inflammatory, type II fatty, and type III sclerotic) further accelerate disc height loss and collapse, contributing to facet joint overload and secondary osteoarthrosis MDPI.

Types (Pfirrmann Grading of Lumbar Disc Degeneration)

Lumbar disc collapse can be classified by the Pfirrmann grading system on T2-weighted MRI?, which correlates signal intensity, nucleus–annulus differentiation, and disc height:

1. Grade I
   Discs display homogeneous high signal intensity with clear distinction between nucleus and annulus and normal height. At L5–S1, Grade I indicates minimal degeneration without collapse Radiopaedia.

2. Grade II
   The nucleus exhibits inhomogeneous signal with horizontal bands, but height remains normal. Early biochemical changes—reduced proteoglycan content—are present though structural collapse is absent Radiopaedia.

3. Grade III
   Intermediate grey signal intensity and unclear nucleus–annulus boundary characterize Grade III. Moderate? disc height reduction (up to ~30%) reflects partial annular disruption and early endplate sclerosis Radiopaedia.

4. Grade IV
   Low signal intensity nucleus, lost boundary distinction, and moderate to severe? height loss (~30–60%) define Grade IV. Collapsed annulus allows osteophyte? formation at vertebral margins, increasing load on posterior elements Radiopaedia.

5. Grade V
   The most advanced stage, Grade V, shows collapsed disc space (<30% of original height), homogeneous low signal, and complete loss of nucleus–annulus differentiation. This collapse often leads to foraminal stenosis? and facet joint arthrosis Radiopaedia.

Causes of Lumbar Disc Compression Collapse at L5–S1

1. Advancing Age
