Management of Lumbar Spondylosis
For lumbar spondylosis, begin with NSAIDs as first-line pharmacological treatment combined with patient education and regular exercise, reserving surgical fusion only for patients with intractable pain refractory to at least 6 months of comprehensive conservative management including physical therapy. 1, 2
Initial Conservative Management (First 6+ Months)
Pharmacological Treatment
- NSAIDs or COX-2 inhibitors are the first-line medications for symptomatic control of spinal pain and stiffness 1, 2
- Level Ib evidence supports large treatment effects on spinal pain with moderate benefits for physical function 1
- For patients with increased gastrointestinal risk, use either non-selective NSAIDs plus gastroprotective agents or selective COX-2 inhibitors 1
- Analgesics (paracetamol, opioids) may be considered for pain control when NSAIDs are insufficient, contraindicated, or poorly tolerated 1
- Prostaglandin E1, epidural steroid injections, and transforaminal injections can provide additional relief for leg pain and neurogenic claudication 2
Non-Pharmacological Treatment
- Patient education and regular home exercise programs are essential components with Level Ib evidence supporting functional improvement 1
- Individual or group physical therapy should be incorporated, with group therapy showing superior patient global assessment scores compared to home exercise alone 1
- Activity modification and bracing may be considered in select cases 3
Important Caveat
Conventional disease-modifying antirheumatic drugs (DMARDs) including sulfasalazine and methotrexate have no evidence supporting efficacy for axial disease and should not be used unless peripheral arthritis is present 1
Surgical Management Criteria
When to Consider Surgery
Surgery should be considered only after failure of at least 6 months of comprehensive conservative treatment including physical therapy and pharmacological management 1
Specific Surgical Indications
For lumbar spondylosis WITHOUT stenosis or spondylolisthesis:
- Lumbar fusion is recommended (Grade B) for intractable low-back pain due to 1- or 2-level degenerative disc disease that has failed conservative treatment 1
- Alternative option: Comprehensive rehabilitation program incorporating cognitive therapy has equivalent outcomes to fusion 1
For lumbar stenosis WITHOUT spondylolisthesis:
- Decompression alone is recommended (Grade C) for symptomatic neurogenic claudication 1
- Fusion is NOT recommended (Grade B) in the absence of deformity or instability, as it has not been shown to improve outcomes 1
For stenosis WITH degenerative spondylolisthesis:
- Decompression plus fusion is recommended (Grade B) as Level II evidence from the SPORT trial demonstrates superior outcomes at every time point for at least 4 years compared to nonoperative management 1
- The specific fusion technique (posterolateral, interbody, instrumented vs non-instrumented) should be selected based on patient anatomy and surgeon experience 1
Critical Pitfalls to Avoid
- Do not use DMARDs for axial symptoms - there is no high-level evidence supporting their use in lumbar spondylosis without peripheral arthritis 1
- Do not add fusion to decompression for isolated stenosis without documented instability or deformity, as instrumented fusion increases fusion rates but does not improve clinical outcomes and may increase complication rates 1, 4, 5
- Do not proceed to surgery prematurely - most patients with lumbar spondylosis respond to conservative management 2, 6
- Avoid systemic corticosteroids for axial disease - there is no evidence supporting their use, though local corticosteroid injections directed at the site of inflammation may be considered 1
