Spinal implant: MAGEC System Model X rods – risk of failure in use (MDA/2020/010)

Manufactured by NuVasive Inc. – risk of end cap separation after implantation.


  • Identify and quarantine all affected devices (see details below).
  • Follow actions recommended in the manufacturer’s Field Safety Notice (FSN).
  • Ensure systems are in place to follow up patients implanted with affected devices.

MHRA has sought expert clinical advice that recommends all patients receive the following additional follow-up to identify end cap separation:

  • Anteroposterior X-ray imaging within 3 months of this alert.*
  • Advise all patients about the possible complications resulting from this issue as described in the manufacturer’s FSN and what alternative treatment options are available. Each patient should be assessed individually using your own clinical judgement.
  • Continue patient monitoring in alignment with the manufacturer’s instructions for use using anteroposterior X-ray imaging instead of ultrasound imaging.
  • Report suspected or actual adverse events involving these devices through your local incident reporting system and/or your national incident reporting authority as appropriate: England, Scotland, Northern Ireland, Wales. You should also report directly to manufacturers if your local or national systems do not.

*In all cases, the benefit of ionising radiation screening should be weighed against the risks from radiation exposure on an individual patient basis, in line with the requirements of The Ionising Radiation (Medical Exposure) Regulations 2017.

Deadlines for actions

Actions underway: 17/04/2020 Actions complete: 10/06/2020

Medical Device Safety Officers (in England)

Ask the manufacturer to add you to their distribution list for field safety notices (FSNs). This is to help with reconciliation.


If your organisation receives an FSN from a manufacturer, always act on it. Do not wait for a communication from the MHRA.

Problem / background

The manufacturer issued a Field Safety Notice, dated 13 February 2020, to inform users of the potential for the end cap component of affected devices to separate from the housing tube after implantation. The end cap is a threaded component which is designed to prevent the ingress and egress of fluid from the mechanism of the MAGEC System. This component may de-thread after implantation, exposing internal components of the actuator. This could lead to accelerated degeneration of the mechanism and release of titanium alloy wear debris. This issue affects only the MAGEC Model X device generation.

The manufacturer says that affected devices might still distract and/or continue serving as an internal brace despite separation of the end cap. However, the aim of this MDA is to provide additional guidance on the clinical follow-up of patients implanted with affected devices.
