Design rationale

Mobile titanium head

An integrated, movable titanium head lets the cage be steered and positioned in the anterior disc space. At the end of insertion the cage is designed to rotate on its rail as the front edge contacts the ventral annulus.

In-line entry

The cage and the holder are aligned at the start, and the front edge is streamlined for entry through the annulus and the initial distraction of the disc space.

Graft space

Wide structural windows and a central opening provide space for bone graft. A tantalum marker shows the position of the cage on radiographs.

Indications

Lumbar and lumbosacral pathologies in which segmental spondylodesis is indicated, for example degenerative disc disease and spinal instabilities
Revision procedures for post-discectomy syndrome
Pseudarthrosis or failed spondylodesis
Degenerative spondylolisthesis
Isthmic spondylolisthesis
The cages are intended for use with supplemental posterior fixation
