Modification of a percutaneous transpedical interbody bone grafting apparatus and its application in cadaveric operation / 南方医科大学学报

<p><b>OBJECTIVE</b>To modify a percutaneous transpedical interbody bone grafting apparatus for better surgical performance in transpedical interbody bone grafting.</p><p><b>METHODS</b>The puncture needle, guide pin and expander were removed from the original design of interbody bone grafting apparatus, with also modification of the bone grafting funnel, obturator, wick and bone harvesting device. Percutaneous puncture and transpedical interbody bone grafting were performed using the modified apparatus on two cadavers, and the operative procedures, bone grafting scope and surgical trauma were observed.</p><p><b>RESULTS</b>This modified apparatus allowed increased bone grafting scope with shortened operative time, simplified operation procedures, and reduced surgical trauma.</p><p><b>CONCLUSION</b>Percutaneous puncture and transpedical interbody bone grafting can be easily and safely performed with the modified apparatus.</p>

Surgery simulation with a percutaneous and transpedical interbody bone grafting apparatus / 南方医科大学学报

<p><b>OBJECTIVE</b>To develop a percutaneous and transpedical interbody bone grafting apparatus for vertebral bone defect reconstruction in thoracolumbar fracture correction via minimally invasive operation.</p><p><b>METHODS</b>The percutaneous and transpedical interbody bone grafting apparatus was designed with CAD software, and the reduction effect, range of bone grafting and surgical complications of the apparatus were investigated in adult cadaveric thoracolumbar body and with computerized surgical simulation.</p><p><b>RESULTS</b>The self-designed apparatus was convenient for percutaneous and transpedical interbody bone grafting that did not give rise to complications. CT showed large bone grafting area with increased density in the vertebral body corrected with this apparatus.</p><p><b>CONCLUSION</b>The designed apparatus allows easy manipulation and efficient bone grafting and repositioning. Minimally invasive interbody bone grafting in thoracolumbar fracture can be easily performed with proper application of the apparatus.</p>
