Study DesignRetrospective study of surgical technique and outcome.ObjectiveThe authors conducted a study to evaluate the ability of the TPS-TL (telescopic plate spacer-thoracolumbar) implant to correct kyphotic deformity and restore vertebral body height after vertebrectomy in the thoracolumbar spine.Summary Of Background DataTPS-TL is a novel vertebral body replacement device that consists of an expandable cage with an integrated plate component for transvertebral screw fixation.MethodsThis is a retrospective study of 20 patients who underwent anterior column reconstruction with TPS-TL after a 1 or 2 level thoracolumbar vertebrectomy. Preoperative and postoperative sagittal alignment and vertebral body heights were radiologically analyzed in all patients. The mean follow-up was 14 months.ResultsPreoperative and postoperative Cobb angles were measured to assess sagittal alignment. The average preoperative Cobb angle was 16.0 + or - 7 degrees. This was reduced to 9.8 + or - 10 degrees at the final follow-up (P<0.001). Percent of ideal vertebral body height was used to assess postoperative restoration of vertebral body height. This value was obtained by creating a ratio of the height of the effected vertebral levels to the height of the adjacent normal vertebral bodies. The mean percent of ideal vertebral body height improved from a preoperative value from 86.2 + or - 2% to 93.1 + or - 6% at the final follow-up (P<0.001).ConclusionsThe TPS-TL implant is effective in restoring vertebral body height and correcting kyphotic deformity after thoracolumbar vertebrectomy.
