Systems, devices and apparatuses for bony fixation and disk repair and replacement methods related thereto
View Patent ↗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.
1. A method for stabilizing adjacent vertebrae of a spine, comprising the steps of:
providing a frame assembly to which is a spacer is removably secured;
securing the frame assembly with respect to the adjacent vertebrae such that the spacer element is disposed in the intervertebral space between the adjacent vertebrae; and
rotating a drill bit in fixed relation to the frame assembly to form an arcuate channel in the surface or sub-surface of the bone, bony structure or vertebra, wherein the spacer is removably secured to the frame assembly so that the drill bit passes through a desired part of the spacer as the drill bit is being rotated to form the arcuate channel.
2. The method of claim 1 , wherein said rotating includes forming a passage through the spacer when rotating said drill bit, the passage being generally congruent with the formed arcuate channel.
3. The method of claim 1 , wherein the spacer includes a pre-formed aperture and wherein the spacer is removably secured to the frame assembly so that the drill bit passes through the pre-formed aperture as the drill bit is being rotated to form the arcuate channel.
4. The method of claim 1 , further comprising the steps of: providing a frame assembly including a plurality of connectors that extend a predetermined distance from the frame assembly, and connecting each of the plurality of connectors to the spacer so as to maintain the spacer in fixed relation to the frame assembly.
5. The method of claim 1 , further comprising the steps of: providing a frame assembly and a clip mechanism coupled to the frame assembly and extending a predetermined distance from the frame assembly, and removably securing the spacer within the clip mechanism so as to maintain the spacer in fixed relation to the frame assembly.
