This is the TTA Cuttable Cage Titanium 4.5 x 18mm. (TTA Cutters not included). As the range of cage widths increases it becomes more difficult to manage a full inventory of conventional cages. We currently stock 24 different variants. Use of cuttable cages allows the surgeon to select the required advancement and trim the cage to length intraoperatively using the dedicated cutters. The cages may be trimmed by 2mm increments.
