1. A method for treating a vertebral fracture, comprising:

  • controllably applying energy from an energy source to a bone cement in an injector system via a heating element disposed in the injector system, at least a portion of the injector system having an outlet port positionable within cancellous bone, the applied energy selectively increasing the viscosity of the bone cement;

    injecting a volume of bone cement having the selectively increased viscosity into the cancellous bone; and

    controlling the viscosity of the cement injected through the injector system via the controlled application of energy so that the bone cement flows into cancellous bone along a flow path between the outlet port and a periphery of the volume, and so at least a portion of the flow path comprises bone cement interdigitated with the cancellous bone.
