Abstract: A system for removing bone growths and realigning bones includes a bone planer and an osteotomy guide. The bone planer includes a hollow sleeve that has an end embeddable within a bone. The bone planer also includes a rotary blade that is coupled to the hollow sleeve. The rotary blade is positioned within and rotatable relative to the hollow sleeve. The osteotomy guide includes a distal portion and a proximal portion. The distal and proximal portions are slidably coupled together. Each of the distal and proximal portions includes an upright that defines a cut guide surface. A space defined between the cut guide surfaces defines a cut path corresponding with a desired cut through the bone.

Abstract: According to one embodiment, a fastener includes a shank defined about a central axis and a head coupled to the shank. The head includes a continuous receptacle circumscribing the central axis. The continuous receptacle includes a radially inner surface that is angled radially inwardly toward the central axis in a head-to-shank direction.

Abstract: An apparatus, system, and method are disclosed for positional fixation of a fastener, including but not limited to the extraction of an orthopedic screw. According to one embodiment, an instrument is provided which accepts a collet designed to conform to a proximal end of a variety of types and sizes of fasteners. The collet is installed through a chuck body, which is seated in a distal end of a handle. A closing mechanism within the handle causes the collet to tightly grip and lock onto the proximal end of the fastener. A compressible distal end of the collet may have longitudinal slits that define jaws for improving gripping flexibility.

Abstract: According to one embodiment, a fastener includes a shank and a head coupled to the shank. The shank is concentrically aligned with a central axis of the fastener. The head extends from a proximal end to a distal end and the shank extends from a proximal end adjacent the distal end of the head to a distal end away from the distal end of the head. The head includes a plurality of receptacles each spaced radially outwardly away from the central axis of the fastener. Each fastener has a radially innermost portion that extends radially inwardly toward the central axis in a direction away from the proximal end of the head.
