Long-Term Risks of Spinal Fusion
Summary
| Key Point | Details |
|---|---|
| What ASD is | New problems at the levels above or below the fused segment due to increased stress |
| How common | Imaging changes in 5–50% of cases; reoperation needed in about 20–25% |
| Main causes | Increased mechanical stress, surgical impact, number of fused levels, spinal alignment |
| Prevention | Minimize fused levels, use MIS, maintain lordosis, core strengthening |
| Progression | Develops over years; regular follow-up is essential |
| Irreversibility | Once fused, it cannot be undone — the first decision matters most |
| Consider SCS | If pain is the main symptom, a reversible SCS trial may be worth exploring before fusion |
