The RJB ™

RJB™ Overview

The RJB system is an Intraoperative Surgical Angle Measurement tool targeted for improving ease, efficiency and cost-effectiveness in procedures for lumbosacral pedicle screw placements.

Device Description

The RJB device can measure the axial and sagittal angles of the instrument relative to gravity. The RJB system only provides measurements for angles in two planes relative to the vertical gravitational plumb line. As such, the RJB device does not provide surgical assistance, guidance, or navigation against patient anatomy. The RJB device is not intended to replace a surgeon’s clinical judgment and has not undergone clinical evaluation. No clinical benefit has been demonstrated or is claimed. For more information, please visit the complete RJB IFU Page.
