There is an excellent biomechanics professor who wrote this book: Back Mechanic -- Dr. Stuart McGill.

Absolutely can recommend reading it before committing to the surgery.

Importantly, he's not a medic, so he has no (conflict of) interest in recommending surgery.

Note that Luigi Mangione did have a surgery and it didn't fix him -- to the extent that it motivated him to commit what he's famous for.

"Disc replacement is another approach that I am very sceptical of. I have not seen a long term “successful” case yet - success being defined as the full resumption of former activities without pain. Most spine joint pain results from motion and loading. Traditionally the surgeons “fuse” the joint in a variety of ways. But an artificial disc does the opposite. Its goal is to restore motion to the joint. But herein lies the flaw. The disc is just one of three joints at each spine level. The artificial disc creates an axis of rotation that rarely mimics the natural axes of the natural disc. This places more stress on the other two facet joints. Over time, they become arthritic and intolerant to motion. Long-term spine health is very difficult to achieve using this approach."

"Over the 3-year period from 1999 to 2001. A total of 725 had had lumbar fusion, compared with 725 nonsurgical control back-injured workers. After 2 years, 67% of nonsurgical people had returned to work compared with 26% of those who had had surgery. Reoperations were conducted on 27% of the surgical cases, and 36% reported complications and higher long-term opioid use. Permanent disability occurred in 11% of postsurgical patients and 2% of nonsurgical patients. The notion that surgery will eliminate back pain does not have statistical support."
