1. A method of treating a vertebra, comprising:
- (a) inserting a delivery device into an interior of a vertebra, the delivery device having a delivery tip with a closed distal end and an aperture that directs the bone cement out of a first side of the delivery device;
(b) extruding bone cement through the aperture and into the bone, wherein the extruded bone cement has a curved shape and a degree of the curvature is controlled via a difference in friction between a proximal side and a distal side of the aperture.
