- 90.5 percent of patients who received the M6-C disc demonstrated a meaningful clinical improvement in the Neck Disability Index.
- A meaningful clinical improvement in arm pain score was seen in 91.2 percent of the M6-C disc patients compared to 77.9 percent in ACDF patients. In addition, this same meaningful improvement was seen in neck pain scores with 90.5 percent of patients who received the M6-C disc compared to 79.9 percent in patients who underwent the ACDF procedure.
- The M6-C disc preserved range of motion in flexion-extension and lateral bending in the study group.
- Prior to surgery, 80.6 percent of the M6-C disc patients and 85.7 percent of the ACDF patients were taking some type of pain medication for the treatment of their cervical spine condition. At 24 months, 14.0 percent of the M6-C disc patients were still taking some type of pain medication compared to 38.2 percent of the ACDF patients.
- Of the patients still taking pain medication there was a seven times higher rate of opioid use with the ACDF patients than with patients who received the M6-C disc.
- Additional surgery at the treated level was needed in 4.8 percent of the ACDF patients compared to 1.9 percent of the M6-C disc patients.
