How Do You Test Spinal Implants?

This is especially true for medical devices manufacturers, where the company’s universal testing systems, help surgeons and doctors all over the world make decisions for their patients based on mechanical property data. The mechanical property data exhibits tensile strength, bend strength, fatigue/durability, torsional capacity, and reliability for a number of devices.

Of all the devices the system tests, one of the most important to a potential recipient’s quality of life, is a spinal implant. ADMET’s spinal implant testing systems are the best way to ensure that these devices go beyond any and all requirements.

ADMET designs all of its systems with ASTM, BSENISO and DIN-compliant materials so medical professionals know they are getting the most reliable, most up-to-date measurements when assessing the qualities of an implant.

Strength

Tension and compression tests on spinal implant testing systems give the user readings on the maximum load a device can take before it yields or breaks. ADMET compression tests have a range up to 600 kN and tension tests tell the tensile properties of the device at the same levels.

Flexibility

Flexibility is every bit as important as strength for spinal implant testing systems because of the range of motion, angles and twists the spine makes. ADMET bend testing systems and customizable bend fixtures can span up to 1200 mm to allow the user to test beyond the normal range of motion and ASTM requirements.

Durability

The ADMET fatigue testing systems exceed ASTM and ISO requirements and testing profiles can be established to show waveforms as simple or as complex as the user desires.
All of these features are fully customizable to ensure users can always test for the exact measurements they want. Systems have a load capacity range from grams of force to 600 kN and a speed range from .001 in/min to 50Hz. Options for data analysis and reporting include: PC based or Touch Panel controllers, standard or extensive calculation analyses, ability to export, see real time plots, and a complete library of ASTM / ISO specifications. Many other aspects of the system are also customizable simply by contacting an ADMET engineer.

With ADMET spinal implant testing systems, doctors and surgeons able to get a more accurate assessment of the strengths and weaknesses of the implants than he/she would with any other system on the market today.
