Abstract: An instrument for use in cartilage removal comprises an elongate body having a first end and a longitudinal axis having a longitudinal direction. A cartilage removal portion is coupled to the elongate body at the first end. The cartilage removal portion includes a plurality of serrated blades substantially perpendicular to the longitudinal axis and adapted for removing material while moving in the longitudinal direction. Each serrated blade has a centroid located along the longitudinal axis.

Abstract: An implant comprises a unitary body including an intramedullary portion connected to an extramedullary portion. The unitary body is configured to attach a first bone section to a second bone section. The intramedullary portion has a first longitudinal axis, and is configured for insertion into the first bone section. The intramedullary portion includes at least one first fastener aperture having an aperture axis oriented obliquely relative to the first longitudinal axis. The extramedullary portion is configured to abut a surface of the second bone section and includes at least one second fastener aperture disposed to transversely receive a bone fastener inserted in the second bone section. The extramedullary portion has a second longitudinal axis offset from, the first longitudinal axis.

Abstract: An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.

Abstract: In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.

Abstract: A surgical tool includes a body defining an opening sized and configured to receive a first bone portion therein, a displacement tip coupled to a first end of the body, the displacement tip sized and configured for insertion into a medullary canal of a second bone portion, and a deployable retention block configured to be transitioned from a first position to a second position. The deployable retention block is configured to maintain the first bone portion in a predetermined position when the deployable retention block is in the second position.

Abstract: A system includes an instrument and a distractor. The instrument includes a shaft extending from a first end to a second end and defining a first axis between the first end and the second end. The instrument further includes a first gear coupled to the first end of the shaft. The instrument further includes a second gear enmeshed with the first gear. The instrument further includes a reamer coupled to the second gear. Rotation of the shaft about the first axis causes rotation of the reamer about a second axis that is non-parallel with the first axis. The distractor includes a first arm defining a first passage and a second arm defining a second passage, each configured to receive a pin. The distractor further includes a retainer configured to engage the instrument to retain the instrument in position. The distance between the first passage and the second passage is adjustable.

Abstract: A guide for a bone cut comprises a guide base having an inner wall defining an opening. The inner wall has a plurality of detents distributed around the opening. The guide base has a proximal surface adapted to contact a skin of a person. An inner collar has one or more spring loaded devices extending outward from the inner collar in opposite directions. The inner collar is mountable with the spring loaded devices fitting within one or more of the plurality of detents. The inner collar has an inner wall defining a bore for receiving a cutting tool. The inner collar is configured to pivot the cutting tool about an axis, for cutting a bone. The axis lies along or parallel to a line along which the spring loaded devices lie.
