Claim Text:
1. A method of forming a void in bony structure, the method comprising the steps of: accessing a bony structure with a cannula; inserting a distal end of a combined drill and reaming device through the cannula and into the bony structure, wherein the combined drill and reaming device comprises a knob, a slotted outer tube, a pivotable blade insertable in the slotted outer tube, a drive shaft extending through the slotted outer tube and operably connected to the pivotable blade, wherein the pivotable blade is capable of changing from a non-deployed drill configuration into a deployed ream configuration via rotation of the knob, wherein in the non-deployed drill configuration the pivotable blade is capable of translating proximally and distally while in the deployed ream configuration the pivotable blade is capable of translating only proximally and not distally; wherein in the non-deployed drill configuration the knob is disengaged from a ratcheting mechanism and in the deployed ream configuration the knob is engaged with the ratcheting mechanism; manipulating the distal end of the combined drill and reaming device to create a void in the bony structure; and removing the distal end of the combined drill and reaming device from the cannula.
