The US Food and Drug Administration has approved X-spine’s Calix PC spinal implant system, an intervertebral body fusion system designed to treat spinal disease.

The Calix PC is made from titanium-coated polyetheretherketone (PEEK).

X-spine president and CEO David Kirschman said the Calix implant system showed 79% greater resistance to expulsion forces than the equivalent non-coated device in laboratory testing.

"The Calix PC provides the benefit of a metallic surface while preserving the desirable qualities of PEEK, namely bone-equivalent modulus and radiolucency," Kirschman said.
