Treatment of Degenerative Lumbar Spine Disease with MRI-Confirmed Nerve Root or Cauda Equina Compression and Lower-Extremity Radicular Symptoms
This protocol applies to patients with degenerative lumbar spine disease who present with lower-extremity radicular symptoms and signs that correspond to lumbar MRI findings — specifically, MRI-confirmed compression of a nerve root or the cauda equina — without significant motion-induced lumbar back pain as the predominant complaint.
Clinical scenario
- Radicular symptoms and signs in the lower extremity matching lumbar MRI findings
- Compression of a nerve root or cauda equina confirmed on lumbar MRI
- No significant motion-induced lumbar back pain as the primary symptom
Treatment approach — partial overview
For MRI-confirmed stenosis compressing a nerve root or the cauda equina with corresponding radicular manifestations, a stability-preserving surgical decompression of the lumbar spinal canal is the principal approach — the complete structured protocol details technique selection, procedural specifics, and the full decision pathway.
Clinical goals at 24 months
- Improvement in Oswestry Disability Index (ODI) score
- Reduction in lumbar back pain and leg pain

- Are there radicular symptoms and signs? Do these correspond to the MRI findings?
- Stenosis causing compression of a nerve root or of the dural sac (cauda equina), as confirmed by MRI, with relevant clinical manifestations and without any significant degree of motion-induced back pain can be treated with decompression of the spinal canal and the neuroforamina.

- Decompression has been shown to yield better long-term results than conservative treatment for lumbar spinal stenosis.
- Malmivaara et al. likewise showed improvements in the ODI score and in back and leg pain (on a 0–20 scale): the mean differences on follow-up at 2 years were, for back pain, 2.1 [1.0; 3.3], and for leg pain, 1.5 [0.3; 2.8].
