What happened
The MHRA identified increased risk of wear and corrosion in cobalt‑chrome dual‑taper modular neck hip replacement systems, affecting devices from five manufacturers used in the UK between 2007 and 2019. As a precaution, NHS trusts and hospitals are advised to identify and invite approximately 750 patients with these implants for clinical review. The action is a safety recommendation.
Quantitative evidence
- Approximately 750 patients currently have affected devices implanted
- Devices available in the UK between 2007 and 2019
- More than 100,000 hip replacements of all types performed annually in UK

Analysis
The following contextual analysis is AI-assisted and separated from the reported primary-source record above.
Scientific context
The action signals growing concern over corrosion at modular neck junctions in hip implants, reflecting known risks of mechanically assisted crevice corrosion at metal interfaces.
Market context
Since multiple manufacturers are named and devices are no longer available, economic impact is limited to recall logistics and follow‑up of approximately 750 patients.
Legal and regulatory context
The MHRA’s measure is a safety recommendation advising clinical review; this does not impose enforcement but follows previous device safety communications.
