Static, Dynamic, and Wear Test Methods of Extra-Discal Single Level Spinal Contructs
Extra-discal single-level motion preserving spinal constructs are tested under static, dynamic, and wear conditions that evaluate implant designs in a functional manner. Wear is tested in a fluid medium, then assessed through gravimetric and dimensional analysis. Wear debris may be analyzed through particle analysis as per ASTM F1877 and ASTM F561.
