摘要
An artificial intervertebral disc exhibiting an anisotropic negative Poissons ratio has been designed and characterized in the laboratory. This disc prosthesis incorporates negative Poisson ratio to prevent bulge which might impinge on nerves, as well as the duplication of compressive axial stiffness of the natural lumbar intervertebral disc. The disc is also compliant in bending and torsion.
