Spinal fusion surgery for chronic back pain does not work at least half of the time.
"They were going to, you know, lock up, you know, give him a spinal fusion, which as I'm sure you know doesn't usually work, at least half the time, and if it does, gives you limited mobility." (said at 0:05:34)
Spinal fusion for chronic low back pain associated with degenerative disc disease has substantial evidence demonstrating limited clinical superiority over intensive non-operative rehabilitation, along with significant complication rates and frequent persistent pain (often termed failed back surgery syndrome). Systematic reviews and meta-analyses of randomized trials indicate that lumbar fusion yields little to no clinically meaningful difference in pain or disability scores compared to non-operative multidisciplinary care, although quantifying this strictly as 'failing at least half the time' requires qualification based on how success (e.g., pain reduction thresholds versus return-to-work or complication rates) is measured.

"The present meta-analysis determined that fusion surgery was no better than nonoperative treatment in terms of the pain and disability outcomes at either short- or long-term follow-up. It is necessary for clinicians to weigh the risk of complications associated with fusion surgery against additional surgeries after nonoperative treatment." (abstract, conclusions, passage verified)

"Among patients with chronic low back pain, lumbar spine fusion surgery showed improvement in functional outcomes related to changes in disability and low back pain when compared with intensive rehabilitation. However, the two treatment options showed no differences with respect to improvement in leg pain and overall patient outcome." (abstract, conclusions, passage verified)
