A fast, cost effective, NHS led service providing independent analysis of explanted medical devices.

Affordable explant analysis

To date there has not been an easily accessible and affordable explant analysis service within the NHS, and so most explanted revised joints end up in the operating room bin. With the introduction of the NHS Implant Analysis Service, hospitals and surgeons now have access to a fast, cost effective, NHS led service. 

The launch of this service enables the cost-effective analysis of explanted devices and provision of expert reports to surgeons and MDTs providing additional data to support patient reviews and insights that can inform clinical practice.

Some of the benefits of explant analysis

Early detection of characteristic failure patterns

Explant analysis enables the early detection of characteristic failure patterns, ensuring that devices which may be performing sub-optimally are rapidly identified

Identify prostheses with atypical features

Corrosion and wear of explants can be quantified and mapped, so that prostheses exhibiting atypical features can be identified

Rapid and accurate analysis

Prosthetic surfaces can be analysed rapidly and accurately to identify issues which may not be visible to the naked eye

Adverse reactions detection (ARMD)

Adverse reactions to metal debris (ARMD) can often mimic infection in their clinical presentation. Analysis of explanted components may identify abnormal wear or corrosive processes commonly associated with ARMD

“In BC (Beyond Compliance) we have always thought that explant analysis of all retrieved implants, particularly if they are novel, should be undertaken. To date this has hardly happened and BC and ODEP are delighted that the NHS Implant Analysis Service is going to facilitate this essential part of implant monitoring.”

“Examination of explanted joints that have failed or caused problems in the body is one of the most valuable sources of data about how and why implants fail.”
