MRI Evaluation: Multilevel Degenerative Lumbar Spine with Scoliosis and Stenosis
Primary Assessment
This MRI demonstrates multilevel degenerative changes with mild spinal stenosis and scoliosis, but these findings do NOT currently warrant surgical intervention—comprehensive conservative management is the appropriate first-line treatment. 1
The imaging shows common age-related degenerative changes that are frequently present in asymptomatic individuals, with 29% of asymptomatic 20-year-olds having disc protrusions, rising to 43% by age 80. 1 The presence of these findings on imaging does not mandate treatment, as they correlate poorly with clinical symptoms. 2
Key Imaging Findings and Clinical Significance
Structural Alignment Issues
- 24-degree leftward lumbar scoliosis: This degree of curvature is mild and does not independently indicate surgical need. 3
- Grade 1 retrolisthesis at L2-L3 and L3-L4: These represent minimal displacement (less than 25% vertebral body translation) and do not constitute significant instability requiring fusion. 4
- Grade 1 anterolisthesis at L4-L5: Similarly, this minimal forward slippage does not meet criteria for surgical stabilization without documented dynamic instability on flexion-extension radiographs. 4
Stenosis Severity Analysis
- L1-L2: Lateral recess effacement with nerve root contact—this is a radiographic finding that may or may not be clinically significant depending on symptoms. 2
- L2-L3: Mild spinal canal stenosis—does not meet threshold for surgical decompression. 5
- L3-L4: Mild spinal canal stenosis with mild-to-moderate foraminal narrowing—insufficient severity for surgical intervention. 5
- L4-L5: Mild-to-moderate spinal canal stenosis—still below the moderate-to-severe threshold required for surgical consideration. 4
Critical Point: None of these levels demonstrate moderate-to-severe or severe stenosis, which is the minimum radiographic threshold required before considering surgical decompression. 4
Recommended Treatment Algorithm
Phase 1: Comprehensive Conservative Management (Minimum 6 Weeks to 3 Months)
Formal physical therapy program with structured exercises focusing on core strengthening, lumbar flexion-based exercises (which relieve stenotic symptoms), and postural training for a minimum of 6 weeks. 1, 2 This is not optional—it is a mandatory prerequisite before any surgical consideration. 4
Activity modification: Reduce prolonged standing or walking periods, use assistive devices if needed, and avoid lumbar extension activities that provoke symptoms. 5
Pharmacologic management: NSAIDs for pain control, with consideration of neuropathic pain medications (gabapentin, pregabalin) if radicular symptoms are present. 4, 2
Patient education: Emphasize the benign, self-limiting nature of mechanical back pain and the high likelihood of spontaneous improvement—approximately one-third of patients with lumbar spinal stenosis improve without surgery, and 50% remain stable over 3 years. 5, 1
Phase 2: Interventional Options (If Conservative Management Fails)
Epidural steroid injections are NOT recommended for chronic axial back pain without radiculopathy, as recent high-quality guidelines issued strong recommendations against their use for chronic spine pain lasting 3 months or longer. 2 Long-term benefits have not been demonstrated for lumbar spinal stenosis. 5
Facet joint injections are NOT recommended based on 2025 BMJ guidelines that issued strong recommendations against joint-targeted injections for chronic spine pain. 2
Phase 3: Surgical Consideration Criteria (NOT Currently Met)
Surgery should only be considered if ALL of the following criteria are met:
Failure of comprehensive conservative management for minimum 3-6 months, including formal physical therapy. 4, 2
Moderate-to-severe or severe stenosis documented on imaging—your current findings show only mild-to-moderate stenosis. 4
Documented instability (spondylolisthesis with dynamic movement on flexion-extension films) OR extensive decompression requirements that would create iatrogenic instability. 4
Significant functional impairment with neurological symptoms that correlate directly with imaging findings. 4
Progressive neurological deficits or unacceptable decrease in quality of life despite maximal conservative therapy. 6
Common Pitfalls to Avoid
Do not pursue repeat imaging in the near term—84% of patients with lumbar imaging abnormalities show unchanged or improved findings after symptoms develop, and repeat imaging rarely detects clinically meaningful changes. 1
Do not interpret radiographic findings as surgical indications without corresponding clinical symptoms—spondylotic changes on MRI are common in patients over 30 years and correlate poorly with the presence of neck or back pain. 2
Do not consider fusion for isolated degenerative changes without documented instability—Grade B evidence states that in the absence of deformity or instability, lumbar fusion has not been shown to improve outcomes in patients with isolated stenosis. 4
Beware of apical vertebral rotation in the setting of degenerative scoliosis—higher degrees of rotation are associated with mechanical low back pain and may predict poor outcomes with decompression alone (odds ratio 8.16 for residual pain). 3 However, this does not change the initial conservative management approach.
Expected Natural History
With appropriate conservative management, the natural history shows: approximately one-third of patients improve, approximately 50% remain stable, and only 10-20% worsen over 3 years. 5 Intensive physical therapy with cognitive behavioral components shows equivalent outcomes to fusion surgery for chronic low back pain without stenosis or instability. 4
Red Flags Requiring Urgent Re-evaluation
Immediately reassess if any of the following develop:
- Cauda equina symptoms (bowel/bladder dysfunction, saddle anesthesia)
- Progressive neurological deficits with motor weakness
- Constitutional symptoms suggesting infection or malignancy
- Severe or progressive neurologic deficits 2
These would warrant prompt advanced imaging (MRI preferred over CT) and specialist referral. 2
