| Spinal fusion has high rates of bony fusion — commonly reported around 90% or higher for single-level fusions in good candidates — and most patients get meaningful pain relief and improved function. Success depends heavily on patient selection, the diagnosis being treated, and factors like smoking, which significantly lowers fusion rates. |
Medically reviewed by Kanwarpaul Grewal, DO — Orthopedic Spine Surgeon, UCSF Complex Spine & Deformity Fellowship. Reviewed July 2026.
What “success” means
There are two questions: did the bone fuse, and did the patient improve. Both are usually favorable when fusion is chosen for the right structural problem, and less predictable when it’s used for nonspecific back pain.
What lowers success
Smoking, poorly controlled diabetes, and unclear pain sources reduce the odds — which is why careful selection matters more than the technique itself.
