The study included 57 patients who underwent total disc replacement from 2003 to 2008. Each patient had at least 10 years of follow-up. Study authors found:
1. Patients reported significant improvement from the preoperative to final follow-up in the Visual Analog Scale and Dallas Pain Questionnaire. The VAS improved from 6.8 to 3.2 while the DPG improved from 63.2 to 45.6.
2. One-third of the patients underwent revision fusion after the initial total disc replacement.
3. The revision patients reported worse outcomes at the 10-year follow-up than the patients who didn’t have revision procedures.
4. Around half — 52.6 percent — of the patients reported they would choose TDR again if they had the same problem.
5. Study authors concluded their work “demonstrated significant improvement in long-term clinical outcomes, similar to previously published studies, and two-thirds of the discus prostheses were still functioning at follow-up.”
