Systems, devices and apparatuses for bony fixation and disk repair and replacement methods related thereto

摘要

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.

主权项

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.
