A new study published in The Spine Journal examined the correlation between patient outcomes and satisfaction two to five years after anterior cervical surgery.
The study authors examined prospectively collected data from the FDA investigational device exemption clinical trial for the Mobi-C cervical disc and anterior cervical discectomy and fusion. There were 512 patients included in the study with data for 60 months after surgery. The researchers found:
1. Two years after surgery, the following factors were excellent predictors of patient satisfaction:
• Neck Disability Index improvement
• Absolute NDI score
• Absolute Visual Analog Scale neck pain score
2. Five years after surgery, the excellent predictors of patient satisfaction were:
• NDI score improvement
• Absolute NDI score
• VAS neck pain score improvement
• Absolute VAS neck pain score
3. The study authors concluded surgeons could predict patient-reported outcomes two and five years after surgery for patients undergoing one- and two-level cervical procedures based on the NDI and VAS neck score.
4. LDR, now owned by Zimmer Biomet, supported the research.
5. The researchers also examined Short Form-12 scores, but those scores were not listed among the predictors of patient satisfaction.
