The researchers examined outcomes from a single center where surgeons used the ProDisc II from Synthes and followed patients for a minimum of five years. There were 181 patients who were included in the study. The researchers found:
• Highly significant improvements in baseline visual analog scale and Oswestry disability index scores at all levels postoperatively.
• VAS scores had a slight deterioration from 48 months onward
• Patient satisfaction remained stable, with 63.6 percent reporting highly satisfied and 22.7 percent reporting satisfactory outcomes.
• There was a complication rate of 14.4 percent.
• Incidence of revision for general or device-related complications was 7.2 percent.
• Two-level replacements also demonstrated significant VAS and ODI scores over baseline, but those results were significantly inferior to one-level cases.
