ABSTRACT:
An apparatus for delivering bone cement into a vertebra includes a cannula and a syringe pivotally coupled to the cannula. Preferably, the syringe is pivotally coupled to the cannula by a pivot fitting that may be detachable from one or both of the cannula and the syringe. The syringe includes a piston slidable in a barrel for advancing the bone cement through an outlet communicating with the cannula. A shaft and cable arrangement or a fluid-driven system may be used to advance the piston within the syringe. The cannula is inserted into a vertebra, and is connected to the syringe. The syringe is pivoted to a desired position, and bone cement is delivered from the syringe through the cannula and into the vertebra.
