SynCages

SynCage-Open

The SynCage-Open is an ideal implant for patients with nonosteoporotic vertebral bodies. It has been specially designed for use in interbody procedures from L1-S1. The design of the SynCage-Open is a fusion of the TIS and SynCage implants.

The cranial/caudal surface is convex in the sagittal plane to provide optimum interface with the endplate geometry.

The implant has a central canal and four lateral windows to receive autograft or other osteoconductive material to allow fusion to occur through the implant.

The outer ring of the implant has been designed to withstand the compressive loads on the outer portion of the vertebral bodies.

The SynCage-Open is available in an anterior, lateral and anterolateral version. All implants come in heights from 9 mm to 21 mm.


SynCage-Curved

The SynCage-Curved as an alternative to the Vertebral Spacer-TR enables surgeons to choose between a polymer and a titanium implant.

The SynCage-Curved has been designed as a scaffold, with central and lateral canals to allow for bone to grow from endplate to endplate, through the implant. The cranial/caudal surface is convex in the medial lateral direction to provide optimum interface with the endplate geometry.

The SynCage-Curved is available in heights from 7 mm to 17 mm.


SynCage-Narrow

The SynCage-Narrow is a metallic version of the Vertebral Spacer-PR. It is designed with saw-tooth teeth, similar to those existing on the PLIF allograft and Vertebral Spacer-PR implants, on the cranial and caudal surfaces thereby increasing its resistance to expulsion compared to the existing Contact Fusion Cage. The surfaces are convex to match the geometry of the vertebral endplates.

The SynCage-Narrow is designed with a width of 8 mm for all heights from 7 mm to 17 mm. Because of this narrow, constant width and the flat insertion technique, only a small window has to be created by a partial laminectomy, lateral to the spinal cord, which does not compromise the facet joints and structural stability of that vertebral level.

Because the SynCage-Narrow is manufactured from a titanium alloy (TAN), less material is necessary and, therefore, it can be designed with lateral windows for fusion, giving the implant a more scaffoldlike structure. Together with the central hole, the implant can receive autograft and allow fusion to occur through and around the implant.This SynCage-Narrow is, at the moment, only available in SUSA territories.
