Abstract

An apparatus for removing an osteophyte includes an elongated member. A portion of the elongated member includes a blunt end. A burr extends from this portion at a location proximal to the blunt end. An alternative embodiment includes a generally tongue-shaped elongated member. The elongated member includes a first portion and a second portion that define a passageway. The second portion includes a blunt end. At least one of a post and a wall extend from the first portion. A burr is coupled the second portion and the passageway at a location proximal to the blunt end. The burr includes a base with a generally pie-slice shaped perimeter, and includes a generally convex surface extending from the base. The generally convex surface includes a smooth portion facing generally toward the blunt end and a perforated, non-smooth portion facing generally toward the first portion of the elongated member.
