The Xia Cortical Trajectory (CT) implants and instruments are built upon Stryker’s leading Xia Spinal System foundation and are used in less invasive LITe LIF posterior lumbar interbody fusion procedures for patients with degenerative disc disease, spondylolisthesis and trauma, among other indications. The cortical trajectory procedure facilitates a smaller midline incision to help achieve decompression, fixation and fusion1. It also is intended to be more muscle sparing than standard open procedures that require lateral dissection, and its reduced incision may allow for more efficient exposure and closure time1.
Brad Paddock, president of Stryker’s Spine division, said the introduction of the Xia 4.5 Cortical Trajectory offering is one of several new products the company will be unveiling at the AAOS meeting, continuing the strong momentum Stryker has achieved in recent years. “The new Xia CT implants and instruments are an important addition to our suite of products designed to facilitate LITe LIF procedures,” Paddock said. “This product introduction reinforces our commitment to providing innovative technology to physicians and their patients with the goal of achieving enhanced outcomes. We look forward to the continued expansion of Stryker’s Spine portfolio of spinal procedural innovations and differentiated technology.”
The Xia CT implants utilize the low profile tulip head of Stryker’s Xia 4.5 Spinal System to allow for maximum visualization, and can be used with the LITe Midline Retractor that allows for optimized visualization of the surgical site without the need for headlamps. The Xia CT implants and instruments offer both cannulated and non-cannulated options. The cannulated screw offering and cannulated tap markers allow for screw insertion over a guide wire. The Xia CT implants and instruments are compatible with existing Xia 4.5 implants and instrumentation.
