Spinal Disc Impingement-Wear Testing under Adverse Kinematic Conditions
The traditional wear test procedure for a spinal disc replacement is adjusted to apply and evaluate wear under adverse impingement conditions using the OIC’s AMTI hip simulator. Wear is measured and analyzed at shorter intervals of 125, 250, and 500 thousand, and at the end of the test at 1 million cycles. Test fluid samples may be collected and examined for wear particle characterization as described in ASTM F1877 and ASTM F561. Wear patterns may be evaluated further using microscopic imaging.
This standard may be customized to suite the design and needs of your spinal device.
