[Modification of a percutaneous transpedical interbody bone grafting apparatus and its application in cadaveric operation].
OBJECTIVE
To modify a percutaneous transpedical interbody bone grafting apparatus for better surgical performance in transpedical interbody bone grafting.


METHODS
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.


RESULTS
This modified apparatus allowed increased bone grafting scope with shortened operative time, simplified operation procedures, and reduced surgical trauma.


CONCLUSIONS
Percutaneous puncture and transpedical interbody bone grafting can be easily and safely performed with the modified apparatus.
