PRODUCT OVERVIEW

Percutaneous Thoracolumbar Fixation Built Around a 5.5 mm Rod Platform

The RHmeditech 5.5 mm MIS Spinal Pedicle Screw System provides a coordinated implant and instrument solution for posterior thoracolumbar stabilization through a minimally invasive approach.

Cannulated pedicle screw options support guidewire-assisted placement, while monoaxial and polyaxial head configurations provide flexibility for different construct requirements. Multiple screw diameters, screw lengths and rod lengths allow the system to be configured for varied anatomies and fixation levels.

A matching minimally invasive instrument set supports screw insertion, rod passage, reduction and final locking. Component selection, compatibility and clinical use must follow the approved instructions for use and applicable requirements in the destination market.

INTENDED APPLICATION

Posterior Thoracolumbar Stabilization Through a Minimally Invasive Approach

The system is designed for posterior non-cervical pedicle screw fixation as an adjunct to fusion where a minimally invasive approach is clinically appropriate. Potential application areas may include thoracolumbar instability, spondylolisthesis, selected fractures and revision procedures. Final patient selection, fixation levels and construct configuration must be determined by qualified surgeons according to the approved instructions for use and applicable local regulations.
