Comparing Treatment Options
Benefits, costs, risks, and long-term outlook organized across all major treatment options — a detailed guide.
1. Treatments Compared: Effect, Cost, and Risk
Comprehensive Treatment Comparison
Basic Information
| Treatment | Hospitalization | Recovery period | Duration of effect | Covered by insurance |
|---|---|---|---|---|
| Medication | Not required | -- | While taking the medication | Yes |
| Rehabilitation | Not required | -- | Requires ongoing participation | Yes |
| Nerve block injections | Not required to a few days | A few days | Days to months | Yes |
| Decompression surgery | 1-2 weeks | 1-3 months | Long-term | Yes |
| Fusion surgery | 2-3 weeks | 3-6 months | Long-term | Yes |
| Minimally invasive surgery | A few days to 1 week | 2 weeks to 2 months | Long-term | Yes |
| SCS | 1-2 weeks | 2-4 weeks | Long-term (adjustable) | Yes |
Cost Comparison
Conservative Treatment Costs (Approximate Out-of-Pocket at 30%)
| Treatment | Cost per session | Estimated annual cost |
|---|---|---|
| Medication | A few hundred to a few thousand yen/month | 10,000-50,000 yen |
| Rehabilitation | 500-2,000 yen/visit | 30,000-100,000 yen |
| Nerve block injections | 3,000-10,000 yen/session | Several tens of thousands of yen |
Surgery and SCS Costs
Decompression surgery, fusion surgery, and SCS are all covered by Japan's High-Cost Medical Care Benefit System (Kogaku Ryoyo-hi Seido). This system puts a monthly cap on your out-of-pocket costs.
| Category | Monthly out-of-pocket cap (from August 2026) |
|---|---|
| Under 70, annual income approx. ¥3.7–7.7 million | ¥85,800 + (bill − ¥286,000) × 1% |
| Under 70, annual income up to approx. ¥3.7 million | ¥61,500 |
| 70 or older, general income (a month with a hospital stay) | ¥61,500 (outpatient-only months: ¥22,000) |
The cap depends on your income category and is subdivided further from August 2027. If a trial is done and falls in a different month from the permanent implant, that can mean two months at the cap, and meal and private-room charges are not covered. See Treatment Costs and the High-Cost Medical Expense Benefit.
The exact out-of-pocket amount depends on your income bracket. For details, ask the hospital billing office or your local municipal government.
Risk Comparison
Risks of Each Treatment
| Treatment | Common risks | Serious risks |
|---|---|---|
| Medication | Stomach/GI problems, drowsiness, dizziness | Kidney damage (long-term NSAIDs) |
| Nerve block injections | Temporary numbness, discomfort | Infection, bleeding (rare) |
| Decompression surgery | Infection, bleeding, temporary symptom worsening | Nerve damage (rare) |
| Fusion surgery | Above + adjacent segment disease | Implant-related complications |
| SCS | Infection, lead migration | Device-related complications |
How to Think About These Risks
Reported complication rates vary widely between studies, and your individual risk depends on your condition, the extent of the procedure, and the facility. So this site does not list figures that would apply to everyone. In general:
- The larger the operation, the higher the risk of complications such as infection and blood clots
- Fusion surgery carries the long-term concern of adjacent segment disease, which is new strain on the levels next to the fused segment
- SCS is easier on the body, but lead migration and re-interventions for adjustment are relatively more common
For your own risk, ask your doctor: "At this facility, how often do complications occur with this treatment?"
2. Who Each Treatment Suits, and Long-Term Outcomes
Who Is Each Treatment Best Suited For?
Conservative Treatment
| Good fit | Not a good fit |
|---|---|
| Mild to moderate symptoms | Severe symptoms |
| Mild neurological symptoms | Muscle weakness |
| Daily life is not greatly affected | Walking is severely limited |
| Prefer to avoid surgery | Bladder or bowel problems |
| Overall health is a concern | Symptoms are worsening rapidly |
Decompression Surgery
| Good fit | Not a good fit |
|---|---|
| Compression is the main cause | Slippage or instability is present |
| Stenosis at 1-2 levels | Widespread stenosis |
| Conservative treatment has not helped | Surgical risk is too high |
| Intermittent claudication is the main symptom | Chronic pain is the dominant problem |
Fusion Surgery
| Good fit | Not a good fit |
|---|---|
| Spondylolisthesis (vertebral slippage) is present | Stenosis is stable |
| Spinal instability is present | Severe osteoporosis |
| Deformity (such as scoliosis) is present | Multiple prior surgeries |
| Extensive decompression is needed | Overall health is poor |
SCS
For Patients Who Have Not Had Surgery
| Good fit | Not a good fit |
|---|---|
| Imaging does not match symptoms | Decompression alone could help |
| Degeneration at multiple levels | Structural instability is present |
| Neuropathic pain is the main problem | A mental health condition is the primary cause |
| Surgical risk is high (older age, health conditions) | Active infection |
| Multi-level fusion is needed but surgical risk is high | Severe dementia |
| Younger and wish to avoid fusion |
For Patients Who Have Had Surgery
| Good fit | Not a good fit |
|---|---|
| Pain persists after surgery | Clear compression remains |
| Reoperation carries high risk | A mental health condition is the primary cause |
| Chronic pain is the dominant problem | Active infection |
| Good results (in a trial, if one was done) | Pacemaker present (requires discussion) |
Long-Term Outcomes
The Outlook at 5 and 10 Years
| Treatment | What tends to happen over time |
|---|---|
| Continued conservative treatment | Living with and managing the symptoms; if they worsen, the treatment plan should be re-evaluated |
| Decompression surgery | The benefit lasts for most patients; over the years, new degeneration may develop at adjacent levels |
| Fusion surgery | The benefit tends to be durable, but adjacent segment disease is the main long-term concern |
| SCS | Maintaining the benefit requires programming adjustments; re-interventions such as lead replacement are more common than with surgery |
Why we do not list figures here: Long-term satisfaction and retreatment rates vary widely between studies, which use different patient groups and different measures. Simple side-by-side numbers would mislead more than help. Ask your doctor about the long-term outlook in your case. With every one of these treatments, care continues after the first procedure, and long-term follow-up matters.
3. Choosing Your Treatment
Treatment Selection Flowchart
Step 1: Assess the Severity of Your Symptoms
| Symptom severity | Next step |
|---|---|
| Mild (daily life is not greatly affected) | Continue conservative treatment |
| Moderate (life is affected but you can walk) | Try conservative treatment for 3-6 months; if no improvement, go to Step 2 |
| Severe / Urgent (cauda equina syndrome, progressive muscle weakness) | Consider surgery immediately |
Step 2: When Conservative Treatment Has Not Helped -- Three Directions
When conservative treatment has not helped enough, consider these three directions. The question is not only whether surgery can fix it: the scale and risk of the surgery should also be part of the decision.
| Direction | When this applies | Specific situation |
|---|---|---|
| A. Surgery is the best option | The compression site is clear, and a relatively small surgery can help | Stenosis at a single level, decompression alone is sufficient, overall health is good |
| B. SCS should be considered first | Pain is difficult to fix with surgery, or the scale and risk of surgery are high | Imaging does not match symptoms, degeneration at multiple levels, neuropathic pain is the main problem, multi-level fusion is needed but surgical risk is high (age, health conditions), younger patient wishing to avoid major fusion |
| C. Consider SCS after surgery | Surgery was performed but pain remains | Chronic pain persists after surgery, reoperation carries high risk |
Key point: Along with "whether surgery is possible," consider "how extensive the surgery would need to be" and "whether the expected benefit justifies the risk." For example, multi-level fusion may be technically possible but places a heavy burden on the body, and SCS may be the safer choice.

- Shows which of the three directions (surgery is optimal / SCS first / observation) applies to your case, including the scale and risk of surgery
"If I choose surgery, what is the chance that pain will remain afterward?"
- Tells you the risk of pain after surgery in advance
"If SCS is an option for me, am I a pre-surgical or post-surgical candidate?"
- Clarifies which patient group you belong to
"What would my actual out-of-pocket cost be under the High-Cost Medical Care Benefit System?"
- Gives you a realistic estimate of the financial burden
"Looking at the long term (5 years, 10 years), which treatment is likely to give the best results?"
- Looks at long-term satisfaction as well as short-term success
"Is it possible to combine treatments (for example, decompression surgery followed by SCS)?"
- Asks whether staged or combined approaches are possible
"Should I get a second opinion? Can you recommend a specialist?"
- Finds out whether more expert input is needed before a complex decision
"How much time do I have to decide? Do I need to decide quickly?"
- Confirms the timeline so you can think it over carefully
"How would each treatment option affect my quality of life? (Work, hobbies, housework, etc.)"
- Covers the practical effect on your daily life as well as medical outcomes
