The system includes a superior inferior component, a connection feature, a housing, at least one rotating member and a cutter. The superior inferior component is engaged to a structure. The connection feature is engaged with the superior inferior component. The housing is engaged with the connection feature. The rotating member is configured to rotate within the housing. The first cutter is engaged with the rotating member such that the rotation of the rotating member translates into rotation of the first cutter, wherein the first cutter rotates about an axis that is generally parallel to a natural surface of the bone. ## Claims ### Claim 1 A system for preparing a bone for receiving an articulating member, the system comprising: a superior inferior component configured to be engaged to a structure; a connection feature engaged with the superior inferior component; a housing engaged with the connection feature; at least one rotating member configured to rotate within the housing; and a first cutter engaged with the rotating member such that the rotation of the rotating member translates into rotation of the first cutter, wherein the first cutter rotates about an axis that is generally parallel to a natural surface of the bone. ### Claim 2 (depends on 1) The system of claim 1, wherein the axis of rotation of the rotating member is angular to the axis of rotation of the first cutter. ### Claim 3 (depends on 1) The system of claim 1, wherein, the axis of rotation of the rotating member is parallel to the axis of rotation of the first cutter; and the axis of rotation of the rotating member is offset from to the axis of rotation of the first cutter. ### Claim 4 (depends on 1) The system of claim 1, wherein, the rotating member comprises a first bevel gear; and) the first cutter is engaged to a shaft, wherein the shaft comprises a second bevel gear configured to interface with the first bevel gear. ### Claim 5 (depends on 1) The system of claim 1, wherein, the rotating member comprises a first gear; / the first cutter is engaged to a shaft, wherein the shaft comprises a second gear configured to interface with the first gear; and the axis of rotation of the first gear is parallel to the axis of rotation of the second gear; and the first gear is engaged with the second gear such that the rotation of the first gear translates into rotation of the second gear. ### Claim 6 (depends on 1) The system of claim 1, further comprising a plurality of cutters, wherein the first cutter is among the plurality of cutters, wherein axis of rotation of at least two of the cutters intersect to define an oblique angle. ### Claim 7 (depends on 1) The system of claim 1, wherein the system comprises a transmission member, wherein the transmission member interfaces with the first gear and the second gear such that the rotation of the first gear translates into rotation of the second gear. ### Claim 8 (depends on 1) The system of claim 1, further comprising a plurality of cutters, wherein at least two of the cutters have different diameters. ### Claim 9 (depends on 1) The system of claim 1, wherein the connection feature comprises a longitudinal axis, and wherein the housing is engaged with the connection feature such that the housing pivots about an axis which is incident at an angle with the longitudinal axis of the connection feature. ### Claim 10 (depends on 1) The system of claim 1, wherein the connection feature comprises a longitudinal axis, and wherein the housing is engaged with the connection feature such that the housing is operable to swing about the longitudinal axis of the connection feature.) ### Claim 11 A method for preparing a bone for receiving an articulating member, the method comprising: engaging a superior inferior component to a structure; engaging a connection feature with the superior inferior component; engaging an housing with the connection feature; enabling rotation of at least one rotating member within the housing; and transmitting the rotation of the at least one rotating member to a first cutter, such that the first cutter rotates about an axis that is generally parallel to a natural surface of the bone. ### Claim 12 (depends on 11) The method of claim 11, imparting rotation in the rotating member by a rotation imparting member, wherein an axis about which the rotation imparting member rotates is incident at an angle with the axis about which the rotating member rotates. ### Claim 13 (depends on 11) The method of claim 11, further comprising rotating a plurality of cutters, wherein the first cutter is among the plurality of cutters, about a single axis of rotation. ### Claim 14 (depends on 11) The method of claim 11, wherein enabling rotation of the rotating member comprises rotation the rotating member about an axis which is perpendicular to the axis of rotation of the first cutter. ### Claim 15 (depends on 11) The method of claim 11, wherein transmitting the rotation of the rotating member to the first cutter comprises: engaging a flexible member with the rotating member and the first cutter; and transmitting the rotation via the flexible member. ### Claim 16 (depends on 11) The method of claim 11, wherein engaging the housing with the connection feature comprises, enabling the housing to operably swing about a longitudinal axis of the connection feature by at least 180 degrees. ### Claim 17 A system for shaping a surface of a bone, the system comprising: an accommodation means for receiving a rotating member, wherein the accommodation means is configured to pivot about a pivot axis; and a cutting means engaged with the rotating member such that cutting means rotates about an axis which is incident to an axis that is perpendicular to the pivot axis. ### Claim 18 (depends on 17) The system of claim 17, further comprising a connection means for engaging the accommodation means with the bone, wherein the cutting means is disposed between the rotating member and the connection means. ### Claim 19 (depends on 17) The system of claim 17, further comprising a connection means for engaging the accommodation means with the bone, wherein the rotating member is disposed between the cutting means and the connection means. ### Claim 20 (depends on 17) The system of claim 17, wherein the cutting means comprises a cutting surface, wherein the cutting surface is partially enclosed in the accommodation means.
