1. A method for performing ablation of a treatment site and delivering cement to an ablation zone larger than and encompassing the treatment site, the method comprising:

  • providing a system that comprisesa cannula having a proximal end and a distal end, and an interior cavity extending between the proximal end and the distal end;

    a stylet received within the interior cavity of the cannula and having a proximal end and a distal end, wherein the distal end is capable of protruding beyond the distal end of the cannula upon insertion of the stylet into the interior cavity thereof;

    at least one ablation probe having a proximal end and a distal end; and

    a drill having a proximal portion with one or more markings and a distal portion, wherein the distal portion of the drill is capable of extending beyond the distal end of the cannula;

    an inflatable bone tamp with an inflatable balloon; and

    cement;

    inserting portions of the cannula and the stylet received in the interior cavity of the cannula into a human body, and positioning the distal ends of the cannula and the stylet adjacent a proximal margin of a proximal subzone of the ablation zone;

    removing the stylet through the interior cavity of the cannula;

    inserting the drill into and through the interior cavity so that the distal portion of the drill protrudes from the distal end of the cannula;

    manipulating the drill so that the distal portion extends across the ablation zone through the treatment site to adjacent a distal margin of a distal subzone of the ablation zone;

    visualizing the position of the cannula and the stylet during insertion thereof, and visualizing the position of the drill during manipulation thereof;

    removing the drill through the interior cavity of the cannula;

    inserting the ablation probe into and through the interior cavity of the cannula so that the distal end is positioned adjacent the distal margin of the distal subzone;

    using the at least one ablation probe to form the ablation zone substantially between the proximal subzone and the distal subzone;

    removing the ablation probe through the interior cavity of the cannula;

    inserting the bone tamp into and through the interior cavity of the cannula so that the inflatable balloon is positioned within the ablation zone;

    inflating the balloon of the bone tamp;

    removing the bone tamp through the interior cavity of the cannula; and

    delivering a volume of the cement into the ablation zone.
