Product Overview

CAPITOL®* preferred angle screws eliminate the challenges associated with posterior CT fusion, with user-friendly construct assembly and a muscle-sparing approach. A wide range of instruments, including the MARS™ Posterior Cervical Retractor, assist in screw insertion.

Features and Benefits


Preferred Plane Technology

Revolutionary pre-angled screws enhance locking cap placement to minimize anatomical disruption.

Non-Threaded Locking Cap

Robust design eliminates cross-threading and directs set screw forces axially against the rod, unlike threaded systems which direct forces radially against the screw head.

Customized Retractor

Retractor adapts to patient anatomy with bayoneted arm attachments allowing for 20° of built-in blade angulation.

*CAPITOL® screws are components of the ELLIPSE® Stabilization System System
