Abstract
Various exemplary methods and devices are provided for removing abnormalities from bone. In general, the methods and devices can be used to allow excess bone to be scraped from a bone surface. In an exemplary embodiment, a scraper tool is provided that includes an elongate shaft having a plurality of blades movably disposed therein. The blades can be configured to move as a unit between a retracted configuration, in which the blades can be entirely disposed within the elongate shaft, and an advanced configuration, in which at least a portion of the blades can extend distally from the elongate shaft and/or flare away from one another. A distal portion of each of the blades can have a radius of curvature corresponding to a radius of curvature of the bone to be scraped.
