Tesera SA Stand-Alone ALIF Cage System

Spine Product Group

The Renovis Tesera® SA Stand-Alone ALIF Cage is a porous titanium Stand-alone Anterior Cage designed to be part of the fusion, rather than merely a vessel for it.

 

Using additive manufacturing, we have created an ideal trabecular structure for bone in-growth, providing excellent long-term fixation. Four screws and an innovative locking system provide immediate fixation and confidence.

Renovis is committed to advancing patient care through better products, based on scientific and clinical data. We commissioned an independent study through IMDS Discovery Research to validate our Tesera Trabecular Technology. Below are images and excerpts from the Twelve Week Draft Report. The final report, with 24 Week data, will be posted upon completion.

Figure 13: This figure shows a comparison of each time point. Black=Titanium, Pink=Bone, Blue=Fibrous Tissue & White=Pore Space. The time 0 specimen shows bone chips (arrows) within the porous structure (PC) and along the drill track in the periprosthetic region (PP). 12 Week specimen shows excellent bone attachment to the porous structure.
