M6-C Artificial Cervical Disc recall and safety concerns: Investigating potential claims

Our specialist Harmful Products team was recently instructed to represent a patient who received an M6-C Artificial Cervical Disc and is currently undergoing medical investigations following concerns regarding the performance of the implant.

The team is investigating potential claims involving the M6-C Artificial Cervical Disc, a spinal implant used in cervical disc replacement surgery.

What is the M6-C Artificial Cervical Disc?

The M6-C Artificial Cervical Disc is a motion-preserving spinal implant designed to replace a damaged cervical disc in the neck. The device was developed to replicate the function of a natural spinal disc by allowing movement while maintaining stability.

Safety concerns and regulatory action

In January 2026, the Medicines and Healthcare products Regulatory Agency (MHRA) issued a Device Safety Information notice concerning the M6-C Artificial Cervical Disc after assessing reports of osteolysis (destruction of bone tissue) and early device failure published in the medical literature.

Patients implanted with the device should be informed of the risks of osteolysis, receive routine annual monitoring, and discuss the need for further investigations and ongoing follow-up with their treating clinicians.

In August 2025, Orthofix issued an Urgent Product Alert Communication stating that changes in disc position, loss of height and peri-prosthetic bone loss may indicate the onset of osteolysis and noted that this could potentially result in neck pain and serious neurological consequences.

What is Osteolysis?

Osteolysis is a condition involving the loss or destruction of bone around an implant. The manufacturer identifies wear debris, material degradation and peri-prosthetic osteolysis as recognised complications that may be associated with device failure and additional surgery.

Potential symptoms reported in connection with osteolysis and implant failure may include:

• Persistent or worsening neck pain;
• Arm pain, numbness or weakness;
• Neurological symptoms;
• Reduced movement in the neck;
• Device loosening or instability; and
• The need for revision or removal surgery.

Not every patient with an M6-C implant will experience complications, and the presence of symptoms does not necessarily mean that osteolysis has occurred. Appropriate medical assessment and investigation are essential.

How can we help?

Our specialist product liability lawyers are investigating whether patients who have suffered injury, complications, revision surgery or other losses associated with the M6-C Artificial Cervical Disc may be entitled to pursue compensation.

We are currently advising a potential claimant who is undergoing investigations relating to an M6-C implant and are monitoring developments closely. We have successfully recovered compensation for patients who had defective artificial discs and other orthopaedic implants in the past.

If you have received an M6-C Artificial Cervical Disc and have experienced complications, have undergone revision surgery, or have recently been contacted about monitoring of your implant, please contact our team for a confidential discussion about your circumstances.
