Static & Fatigue Testing - Orthopaedic Implants
Our static and fatigue programmes expose your orthopaedic implants to a series of rigorous tests to characterise the mechanical strength of your design, coating, or material. Static and fatigue tests are designed to push your implants to their limits, allowing you to gather data for research, product development, and regulatory submissions. When standard tests are not suitable, our expert team can work with you to modify or design tests specific to your implant and application.
Using supporting analytical capabilities, such as White Light Interferometry (WLI), Scanning Electron Microscopy (SEM), and Digital Image Correlation (DIC), we track the stresses and strains on your implants so you can see the areas where failures begin. With real-time analysis we provide visuals of the failures in action, along with the supporting data and interpretation. These advanced analyses help to inform future R&D as well as being used in regulatory support of your current implants.
If you are looking to:
- Simulate and evaluate the static & fatigue loading performance of your new orthopaedic implants
- Compare a new design with an existing one
- Outsource your orthopaedic implant static & fatigue testing to accelerate new product developments and avoid in-house delays
- Find a supplier that can provide a comprehensive service and the full suite of information you require for your regulatory submission
- Visualise the areas of your implant that take the main force of stresses and strains
- Understand failure mechanisms…
…then we can help.

White Papers
In this white paper we look at why the testing of implants is so important. Traditional test methods and their limitations are detailed and adverse event testing is discussed
In this white paper we review the key tribology & testing techniques available for orthopaedic implants
This white paper provides an introduction to the theory behind fatigue in general, and the factors that affect how materials perform in fatigue
This white paper offers additional guidance that could help support implant manufacturers in their decision-making and justifications for regulatory submissions
Wear simulation for implantable knee, hip and intervertebral spinal disc prostheses have all been well documented and standardised tests methods have been created to assess the performance of these medical device implants
This white paper highlights some of the testing involved in ISO 13356 and discusses how recent and ongoing research into ceramic processing provides opportunities to meet product improvement challenges
