1. A guide assembly for an impactor, comprising:
an impactor guide having a guide magnetic region and an opening having an opening axis, wherein the opening constrains movement of the impactor to translation along the opening axis of the opening;
a guide receptacle having a receptacle magnetic region for receiving the guide magnetic region to form a magnetic interface between the receptacle magnetic region and the guide magnetic region to locate the opening axis along a first axis and having a magnetic attraction force sufficient to hold the impactor guide to the guide receptacle when translation of the impactor is substantially along the first axis and insufficient to hold the impactor guide to the guide receptacle when an impaction force greater than a predetermined threshold is applied to the impactor along a second axis that is not substantially parallel to the first axis.
