ABSTRACT:
A tool for dilating tunnels in bone, in order to compact the cancellous bone around the tunnel and providing better holding for interference screws and the like, comprises a plurality of elongated segments mounted for radial motion with respect to an axis of elongation. When actuated, the segments move radially outwardly, parallel to the axis of elongation, compacting the bone.
