Description
The basic shape of the TETRIS II devices is a hollow structual frame having a rounded, tapered leading face. The upper and lower aspects of the implant are open. Surface spikes assist in the positive anchorage and seating of the implant between the vertebral bodies. The device is avaiable in a variety of sizes and angulations thereby enabling the surgeon to choose the size best united to the individual pathology and anatomical condition.
