The system comprises first and second cannulas and first and second void forming tools which are sized and configured to be advanced respectively through the first and second cannulas. The first and second void forming tools are each adapted to form a void in cancellous bone of a desired shape and volume. A nozzle is provided which is sized and configured to pass through at least one of the first and second cannulas. The nozzle includes a nozzle exit and an interior passage to deliver a volume of filling material into a void through the nozzle exit. The system also comprises a stylet which is sized and configured to be received by the interior passage of the nozzle and urge filling material from the nozzle.
