Unlike conventional TTA cages, cuttable TTA cages can be trimmed to length intra-operatively. This permits a smaller cage inventory to cover a larger range of patient sizes. The cages may be trimmed by 3mm increments. Our cages should be cut using the special TTA cage cutters, which are designed with narrow jaws to reach in between the fins of the cage. These cutters should only be used for cuttable TTA cages.
