Recent studies have raised serious concerns about the long-term safety of the M6-C cervical artificial disc. According to a study published in the European Spine Journal, up to 34% of patients who underwent M6-C disc replacement developed severe osteolysis (bone loss) requiring revision surgery and spinal fusion.

This alarming failure rate was linked to polyethylene wear debris from the M6-C implant—significantly higher than any other cervical disc replacement on the market.

Key Findings from the European Spine Journal Study:

• 34% of patients experienced severe osteolysis.
• Bone loss led to revision surgery and spinal fusion.
• Polyethylene wear debris was identified as the cause.
