Overview

This document presents technical information about the PROXiphias™ Posterior Fixation System, specifically focusing on thoracolumbar pedicular screws used in spinal surgery. The system includes various types of screws designed for posterior thoracolumbar fixation, including polyaxial and monoaxial screws, as well as specialized listhesis screws.

Main Components and Screw Types

• Polyaxial Thoracolumbar Posterior Pedicular Screws: Allow multi-directional angulation for flexible placement.
• Polyaxial Listhesis Thoracolumbar Posterior Pedicular Screws: Designed for cases involving vertebral slippage (listhesis).
• Monoaxial Thoracolumbar Posterior Pedicular Screws: Fixed axis screws providing rigid fixation.
• Monoaxial Listhesis Thoracolumbar Posterior Pedicular Screws: Monoaxial screws tailored for listhesis conditions.

Design Features and Benefits

• Torx Designed Setscrew: Provides more reliable tightening, reducing the risk of loosening.
• Toothed Surface Feature: Ensures a stronger connection between components.
• V-Shaped Thread Design: Enhances pull-out strength by improving bone tissue engagement.
• Cutting Flute Design: Facilitates easier insertion into bone, reducing insertion torque and trauma.

Sizes and Codes

The document includes extensive listings of screw sizes and corresponding product codes for each screw type (polyaxial, monoaxial, listhesis variants). Sizes range approximately from 4.5 mm to 8 mm in diameter, with various lengths available to accommodate different patient anatomies and surgical requirements.

Additional System Components

• Thoracolumbar Spinal Connectors: Components such as PROSCOBE™ connectors are mentioned, which facilitate rod and screw assembly.
• Spinal Rods: Various rods compatible with the fixation system are referenced, though detailed specifications are not fully legible.
