Systems, methods, devices and device kits for fixation of bones and spinal vertebrae
First Claim
1. A method for stabilizing adjacent segments of a mammalian bone, comprising the steps of:
- forming a through aperture in each of the adjacent bone segments;
providing an arcuate implant member (a) having a length that is sufficient so the arcuate implant member extends between the two adjacent bone segments, (b) having a cross-section sized so that portions of the arcuate implant member including ends thereof extend through the preformed aperture that is formed in each of the two adjacent bone segments, and (c) being configured so that the arcuate implant member lies in a plane as it extends between the adjacent bone segments and as the portions thereof extend through the preformed apertures;
implanting the provided arcuate fixation member so that (i) it extends between the adjacent bone segments, and (ii) so that the portions of the arcuate fixation member including ends thereof extend through the preformed apertures in each of the adjacent bone segments; and
wherein the apertures formed in each of the two bone segments define an arcuate path in the plane and wherein the provided arcuate implant member is further configured so as to correspond to the arcuate path defined by the apertures.

Abstract
Featured are methods for fixing adjacent vertebrate of a spine that utilize an implant member, which preferably is arcuate. Preferred methods of the invention for stabilizing adjacent vertebrae of the spine, include forming an aperture in each of the adjacent vertebrae and inserting an implant into the apertures formed in each of the adjacent vertebrae so that the implant extends between the adjacent vertebrae and through the intervertebral space. An alternative method for fixing adjacent vertebrae of a spine includes the step of forming a common channel in and between the adjacent vertebrae and inserting an implant in the channel so as to bridge between the adjacent vertebrae. Also featured are methods for stabilizing adjacent segments of a bone, fixation systems and fixation kits.

9. A method for stabilizing adjacent segments of a mammalian bone, comprising the steps of:
-
forming an arcuate through aperture in each of the adjacent bone segments; implanting an arcuate fixation member so that it extends in a plane between the adjacent bone segments and so portions of the arcuate fixation member including ends thereof extend through the preformed aperture in each of the adjacent bone segments and so the arcuate fixation member lies in a plane as it extends between the adjacent vertebrae and as the portions thereof extend through the preformed apertures; and wherein the step of forming includes forming the through aperture by one of drilling or ablation of the bone by an energy source.

10. A method for stabilizing adjacent segments of a mammalian bone, comprising the steps of:
-
forming a through aperture in each of the adjacent bone segments; wherein the step of forming includes drilling the through aperture in each of the adjacent bone segments so as to create intersecting apertures with convergent paths; and implanting an arcuate fixation member so that it extends in a plane between the adjacent bone segments and so portions of the arcuate fixation member including ends thereof extend through the preformed through aperture in each of the adjacent bone segments and so the arcuate fixation member lies in a plane as it extends between the adjacent vertebrae and as the portions thereof extend through the preformed through apertures. - View Dependent Claims (11, 12, 13, 14, 15)
