Elective Lumbar Decompression With Fusion Is Associated With Increased Mortality Compared With Decompression Alone: A National Propensity-Matched Analysis of Aging Cohorts
Global Spine Journal · 30 Jul 2026
† Impact is the editorial-priority score. All scores are out of 100. Clinical is a stored clinical-importance score from the earlier method; it has not been recalculated.
Why it matters
This raises a real concern for how surgeons counsel elderly patients about adding fusion to decompression when there is no clear structural indication like instability or deformity.
The evidence
This retrospective database study used TriNetX to compare adults with degenerative lumbar disease (no instability) who had decompression alone versus decompression plus fusion, matching by age decade and frailty. Fusion was linked to much higher mortality at every time point studied, most strikingly a 30-day mortality of 4.19% versus 0.68% in octogenarians (OR 6.34), with the gap persisting out to two years (13.24% vs 4.61% in the 80s group).
30-day all-cause mortality: Odds ratio 6.34 (95% CI 3.236 to 12.424; units not reported). The interval favours the comparator; the size of the disadvantage needs clinical interpretation.

For journal club
1.In an octogenarian with degenerative stenosis but no radiographic instability, how should this absolute mortality gap change the way you counsel about adding fusion versus doing decompression alone?
2.If a patient has significant mechanical back pain suggesting possible occult instability not captured on imaging, how should surgeons balance the theoretical benefit of fusion against this study's mortality signal?
