Abstract
Abstract A clamp for securing a rod adjacent to a bone includes a rod holder constructed from shape memory material. A bone hook also constructed from shape memory material connects to the rod holder to affix the rod holder adjacent to the bone. The bone hook consists of a pincer that encircles the bone or, alternatively, two separate members coupled together during surgery to encircle the bone. A blocker constructed from shape memory material fits within the rod holder to secure the rod within the rod holder. The blocker permits slidable motion of the rod within the rod holder or, alternatively, rigidly secures the rod within the rod holder.
