ASTM F1717 defines methods for static, fatigue, and torsion testing of spinal constructs to minimize failure from normal patient activity and fatigue.
ASTM F2077 reveals the axial-compression, compression-shear, and torsion tests needed to understand spinal intervertebral body fusion devices.
The 8874 axial torsion system aligns with the needs of static and cyclic testing on implants for spinal intervertebral disc prostheses in accordance with ASTM F2346.
In vitro conditions need to be reproduced when testing the axial loading needed to insert a bone screw into laboratory material following ASTM F543.
From ASTM F543 and ISO 6475, bone screw manufacturers are required to use torque tests to replicate the torsional forces from implantation in surgery.
The 8874 system can test the laxity of knee joints in simulated conditions before they are used for a total knee replacement and impacted by the surgery.
Bone Screws are used as internal fixation devices to secure implants, fracture fixation plates, or to create an anchor into bones for sutures and other devices. ASTM F543-13 contains four testing annexes that outline tests to evaluate bone screws.
