Abstract
AIM: The treatment of massive diaphyseal tibial bone defects remains challenging with poor results seen from treatment modalities other than bone transport (BT). Current methods of BT require lengthy periods in a circular external fixator. Despite recent modifications in BT techniques via circular external fixator such as multifocal transport and immediate intramedullary nailing after docking, circular external fixation remains poorly tolerated with a high complication profile. Newer technologies such as magnetic lengthening nails have shown promise to provide alternatives to BT without resorting to long-term circular external fixation. Plate-assisted bone segment transport (PABST) has demonstrated success as an all-internal BT technique. Prior case reports have shown a modest ability to treat massive defects with varying success. TECHNIQUE: A novel all-internal cable and pulley augmentation to a PABST technique for a massive (185 mm) tibial defect was utilised during a retrograde transport. The authors describe a patient scenario in which this augment allowed continued transport that could not be treated with an additional Precice nail recharge. CONCLUSION: Augmentation of PABST with a cable and pulley construct can successfully treat massive diaphyseal defects. CLINICAL SIGNIFICANCE: This cable and pulley modification to PABST allows for the treatment of massive tibial defects without the need for magnetic lengthening nail exchange or conversion to external fixation.
