Inertia® One-Shot Pedicle Screw System

Nexxt Spine expands its INERTIA® Pedicle Screw System with the introduction of the One-Shot™ Pedicle Screw and instrumentation. The introduction of these components provides the surgeon flexibility to choose from an open, mini-open or MIS procedure. The One-Shot Pedicle Screw is designed specifically for surgeons who wish to utilize a guided screw insertion technique without the use of Kirschner wires.

A unique single-step screw closure mechanism minimizes the chances of cross-threading and significantly reduces head splaying. The system also features a "Rod Capture Mechanism" for retention of the rod within the screw head, generous polyaxial screw angulation and a low profile design.
