Claim 11:
12. A method of reducing acetabulum bone damage during insertion of a cup implant gripped on its outer surface, the method comprising the steps of: (a) providing an implant-engagement arm of an impactor head, wherein the implant-engagement arm is rotatably translatable such that the implant-engagement arm has a dynamically-movable virtual pivot point; and (b) providing a release path on which an implant outer-surface engagement element travels, the release path originating at an implant-engagement condition of the implant outer-surface engagement element, so that, when moving to an implant-release condition, a bone space required to accommodate a lateral arm end of the implant-engagement arm is reduced, wherein the dynamically-movable virtual pivot point results in the implant outer-surface engagement element having at least a reduced movement outwardly when moving to the implant-release condition.
