Spinal Implant Axial & Axial Torsion Test Systems -- Testers & Machines

Testing Accessories -- Test Fixtures


Spinal devices are the fastest growing segment of the biomedical industry with fusion (pedicle screw systems, intervertebral fusion devices, vertebral body fusion devices, etc.) and non-fusion (disc nucleus replacements, intervertebral disc prosthesis, screw or hook based stabilization spinal systems without fusion) developments occurring at a quick pace.

Testing requirements include static and fatigue tests in a variety of loading modes including axial, torsional, bending, shear , flexion/extension, lateral bending, and axial rotation.

Orthopedic devices implanted in the body must undergo static and fatigue tests that mimic ten years of product life to be considered acceptable. Spinal implants and constructs are tested according to various ASTM and ISO standards and typically require static tension, compression and torsion testing, and fatigue tests. The typical medical device developer needs a versatile proven test system that can do both types of tests and one that can expand to combined axial torsional loading. 800LE test systems are servo-all-electric systems that are rated to produce the high loads needed for static tests and the high (to 20 Hz) speeds needed for fatigue testing of materials, devices and components. They require single phase 110V or 220V electric power. No special utilities such as pneumatic air, hydraulics or water are needed. TestResources configures each system to match required load and speed requirements.

Static and Fatigue Test Systems - Single Channel - Axial or Torsional - Static & Fatigue - Expands to Multistation or Multiaxis as needed. Fatigue Testers are required when first testing devices, because developers must generate the required 5 to 10 million compression-compression cycles at speeds to 20 Hz. We also offer servohydraulic load frames - including axial torsional test systems

Biaxial tests on spine fixators, spinal constructs, spine segments and other components require combined axial and torsional tests. Setups can apply static or dynamic forces while acquiring test data. Load bearing activities can be simulated on subsections of the spine such as functional spine units or lumbar and cervical sections. All spinal products require extensive mechanical tests due to the consequences of potential catastrophic failure. Simple static testing is required to evaluate the compressive, tensile and torsional loading required to fracture a spinal device. Fatigue life tests are critical because fatigue failure is more common than catastrophic failure. Loading test samples with load-controlled sinusoidal waveforms is most common, and tests last in excess of five million (10 MM) cycles.

Standard test methods are evolving within the industry for spinal products. ASTM F1717 relies on ultra high molecular weight polyethylene (UHMWPE) blocks rather than vertebrae to eliminate variances that bone properties and geometry introduce.

TestResources testers are configured to match specific customer requirements and typically perform static and fatigue tensile, compression and torsion tests. With the capabilities of our 2350 Servocontroller, high accuracy and flexible control of multiple channels of actuators are now possible. Software records load-displacement curves and performs calculations required by the standard.
