Abstract: The present invention features new methods, apparatuses and devices for fixing adjacent bone segments, segments of a bony structure and adjacent vertebrate of a spine. The methods, apparatuses and devices utilize an apparatus for forming a channel in a surface of the bone or bony structure segments or adjacent vertebra or a channel submerged within the bone or bony structure segments or adjacent vertebra. In more particular embodiments such apparatuses and methods including forming an arcuate channel and which channel can receive therein a curved rod or implant member. Also featured are systems, apparatuses and methods for removably suspending a spacer in the intervertebral space while forming such a channel as well as systems, apparatuses and methods for use of dynamized implant members.
