CATAMARAN™ SIJ Fusion System

CATAMARAN™ SIJ Fusion System

The CATAMARAN™ SIJ Fusion System offers a new surgical solution that places a single implant directly into the SI joint, bridging the sacrum and ilium with a Posterior Inferior surgical approach.

Posterior Inferior Sacroiliac Approach

Known Trajectory
Standard and known entry point, trajectory, and angle that mimics SI joint injection. The surgical access pathway is angled away from critical neural and vascular structures.

Favorable Entry Point
To facilitate arthrodesis, direct visualization of the SI joint provides the entry point to decorticate the joint.

Optimized Placement
The CATAMARAN™ Fixation device is designed for maximum fixation in the dense cortical bone of the SI joint, avoiding the dorsal gap.

Titanium Implant Technology for Single Implant Surgery

The CATAMARAN™ Fixation Device is designed to span the SI joint with one pontoon in the sacrum and one pontoon in the ilium, providing fixation with a single implant. The two pontoons are joined by an osteotome bridge.
