    摘要： An elongated shaft is sized and configured to establish an access path to bone having an interior volume occupied, at least in part, by cancellous bone. The elongated shaft includes a generally closed distal end portion and a side opening spaced from the closed distal end. A first tool is sized and configured to be selectively inserted into the shaft and selectively removed from the shaft. The tool includes a region that, when the first tool is inserted into the shaft, is capable of being aligned with and advanced through the side opening to project outside the side opening and contact cancellous bone. A second tool is sized and configured, upon removal of the first tool from the shaft, to introduce into the shaft a bone filling material for discharge through the side opening into the cancellous bone contacted by the first tool.
