Design rationale

Bullet-shaped front edge

The tapered anterior profile reduces insertion resistance and is intended to allow atraumatic delivery into the prepared intervertebral space. This is useful in a posterior approach, where the working window is small.

Open graft surfaces

The upper and lower surfaces are open, so graft sits in contact with the endplates. Wide graft windows and the central opening are intended to increase the volume of graft that can be placed.

Teeth and biconvex profile

Retaining teeth and a biconvex profile are designed to resist migration. The threaded surface on the upper and lower faces is intended to add fixation to the endplates. The cage is intended for posterior use in mechanical instability and spondylolisthesis.

Tantalum markers

Integrated tantalum markers give fluoroscopic feedback on placement within the disc space.

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
