Why a spine surgeon started offering spinal cord stimulation

In short

• Fusion is a permanent change to the spine; its benefit only shows after surgery.
• A stimulator is tried for about a week before anything is implanted.
• It does not work for everyone. In our own patients about 8 in 10 improved by our measure, and about 6 in 10 would recommend it. These are real-world clinic data, not a trial.
• Best window: pain for more than six months, but not yet for many years.

Summary

Early in my career I moved hospitals every one to three years, so I rarely saw what happened to patients long after surgery. Once I followed them for years, some came back, with new problems that began with the operation itself. Fusion can be the right call, but it is permanent.

I used to dismiss spinal cord stimulation. Then an older man with severe back pain, for whom a long fusion was too risky, tried a one-week trial. His pain came down and he walked again. The field had moved on: newer stimulation does not rely on tingling, and back pain itself became a target.

The key difference for patients: a fusion is like buying a car without a test drive. A stimulator trial is the test drive. If it does not help, the leads come out and every other option is still open.

   Successful outcome: 9 of 19 with stimulation vs 3 of 26 with reoperation. Crossover: 14 of 26 from reoperation to stimulation; 5 of 24 the other way.
