Claim 9:
10. An implant system comprising:
a prosthetic component having a distal portion arranged to be coupled to an end of a bone and a proximal neck portion;
an articulation component arranged to couple to the proximal neck portion; and
a plurality of differently sized collars, each collar comprising a plate having a neck hole, the neck hole and the proximal neck portion being sized and adapted such that the proximal neck portion is configured to be received within the neck hole of each collar of the plurality of differently sized collars, each collar having a plurality of suture holes for coupling the plate to bone fragments or soft tissue, each collar being lockable with respect to the proximal neck portion to prevent rotation, whereby a user may select one of the collars based upon a size of the articulation component,
wherein the plate of each collar of the plurality of differently sized collars has an outer periphery formed from a first curved edge defined by a first radius and a second curved edge defined by a second radius which is larger than the first radius and wherein the first radius is the same as or smaller than a radius of the articulation component and the first curved edge transitions directly into the second curved edge,
wherein the plate of at least one collar of the plurality of differently sized collars is generally planar and of a generally uniform thickness, and
wherein the proximal neck portion is configured to extend past a proximal side of each collar when each collar is locked with respect to the proximal neck portion.
