LBP: Disc prosthesis surgery improves pain and disability compared to rehabilitation
BMJ. 2011 May 19;342:d2786. doi: 10.1136/bmj.d2786179 patients were randomized to determine the efficacy of disc prosthesis surgery compared to non-operative rehabilitation in the treatment of low back pain. Pain and disability outcomes were evaluated over 2 years, along with return to work and mental health criteria.

The clinical importance of ODI reduction can be debated, however.
