Apparatus for compression, comprising: a compression plate comprising first and second opposing regions connected together by an elastic bridge member, wherein the elastic bridge member has a non-linear configuration in its unbiased condition but is capable of being elastically deformed to a more linear configuration upon application of force to the elastic bridge member, and an opening formed in each of the first and second opposing regions, wherein the opening in each of the first and second opposing regions is configured to receive a fastener such that the openings in the first and second opposing regions are separated by a first distance when the elastic bridge member is in its non-linear configuration, and openings in the first and second opposing regions are separated by a second distance when the elastic bridge member is in its more linear configuration, and wherein the second distance is greater than the first distance.
