M6‑C Artificial Cervical Disc: safety concerns and what they may mean for patients

A UK safety notice issued by the MHRA in January 2026 followed reports of complications including bone loss (osteolysis), implant failure and the need for further surgery.

Hospitals are now contacting affected patients and placing them under ongoing monitoring programmes, even where no symptoms are currently present.

While not every patient will experience problems, some have reported worsening neck pain, neurological symptoms or the need for revision surgery.

Where complications arise, there may be different legal routes depending on the circumstances. These can include claims relating to the safety of the device itself, or clinical negligence if the care, advice, or follow‑up provided fell below a reasonable standard.

Each case will turn on its facts, particularly around consent, monitoring, and how any complications were managed.
