Design rationale

Low-profile entry

The low-profile pre-expansion geometry is intended to make insertion atraumatic and to reduce retraction of the dura. The cage passes through the posterior window at its smaller height and gains its working height once it is in position.

Marker and serrated surfaces

A tantalum marker sits in the expanding mechanism and allows verification in situ on fluoroscopy, which helps the surgeon judge expansion. Serrations on the upper and lower surfaces are designed to give primary stability and to resist migration of the implant.

Holder and extractor

Expansion is driven by turning the rear part of the ALLIGATOR-EXP holder. For removal, a dedicated extractor is placed behind the implant, and sliding impact retracts the cage.

Indications

Revision procedures for post-discectomy syndrome
Pseudarthrosis or failed spondylodesis
