ASTM F2193 – Standard Specifications and Test Methods for Components Used in the Surgical Fixation of the Spinal Skeletal System

Test methods is this standard are intended to provide a comprehensive reference for the components of systems used in the surgical fixation of the spinal skeletal system.  Spinal components covered in this test method are Metallic Spinal Screws, Metallic Spinal Plates and Metallic Spinal Rods.  Typically, six (6) tests are performed for each test method.

If the user is interested in evaluating the next level in the spinal fixation system chain, the interconnections between individual components and subassemblies (two or more components), the user should consult Guide F1798.  At the highest level in this chain is Test Methods F1717, which is used to evaluate an entire construct assembled from many components and involves numerous interconnections and several sub-assemblies.
