Xia Cannulated Polyaxial Screws
Minimally invasive systems have been designed to reduce tissue trauma through smaller incisions. The Xia cannulated polyaxial screw has been developed to facilitate screw implantation due to the reduced visualization within the narrower working channels. Xia facilitates surgeons implanting the Xia Polyaxial titanium screws through a less invasive posterior approach by following the path of the guide wire. This is accomplished with streamlined instrumentation to maximize visualization while minimizing the complexity of the Xia Titanium system.
Key advantages include:
- Cannulated screw follows the path of the guide wire to enhance proper screw placement.
- Equivalent strength to non-cannulated screw under static corpectomy conditions*
- Patented closure mechanism lessens potential for cross threading when working through minimally invasive approach
- Depth markings on guide wire provide real time feedback to minimize surgical and fluoroscopy time
- Instruments designed for working through minimal incision
