Abstract
Featured are a methods, systems, apparatus, and devices for fixing adjacent bone segments, segments of a bony structure and adjacent vertebrate of a spine utilizing an implant member as well as device kits related thereto. The methods, apparatuses and devices utilize an apparatus to forming a channel or aperture in or within the bone or bony structure segments or adjacent vertebra. In more particular embodiments such apparatuses and methods including forming an arcuate channel or aperture and which channel can receive therein a curved rod or implant member, which also preferably is arcuate, and avoids the associated problems with prior cage or straight rod and screw systems.

7. A method for stabilizing adjacent vertebrae of a spine, comprising:
-
providing a positioning apparatus including two guide sleeves, each guide sleeve having a long axis;
locating the two guide sleeves with respect to the adjacent vertebrae such that a vertex formed by the long axis of each guide sleeve is located in the intervertebral space for the adjacent vertebrae;
forming an aperture in each of the adjacent vertebrae using the guide sleeves; 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. - View Dependent Claims (8, 9, 10, 11, 12, 13, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

47. A method for fixing two adjacent vertebrae to facilitate a bony union thereof, comprising:
-
performing a diskectomy of an intervertebral space;
transecting a segment of bone from a surface of a vetrebra bordering the intervertebral space;
freeing the segment of bone from the surface of the vertebra from a horizontal to a vertical plane;
securing the segment of bone in the vertical plane to span the intervertebral space;
thereby fixing two adjacent vertebrae to facilitate a bony union thereof.

-
48. A method for stabilizing, adjacent vertebrae of a spine, comprising:
-
providing a positioning apparatus including a pivot arm that is rotatable about a pivot point;
locating the positioning apparatus with respect to the adjacent vertebrae such that the pivot point is disposed between the adjacent vertebrae;
forming an aperture in each of the adjacent vertebrae responsive to rotation of the pivot arm about the pivot point; 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. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)

60. A method for stabilizing adjacent vertebrae of a spine, comprising:
-
providing a cutting device including a cutting implement having midpoint;
positioning the cutting device proximal a surface of the adjacent vertebrae and so that the cutting implement midpoint is located between the adjacent vertebrae;
cutting a common channel in the adjacent vertebrae with the cutting implement; and
inserting a biscuit implant into the common channel so that the implant extends between the adjacent vertebrae and through the intervertebral space, the space between the adjacent vertebrae. - View Dependent Claims (61, 62, 63)

64. A spinal fixation kit comprising a cutter bracket sub-system and a fixation member, wherein the cutter bracket sub-system includes:
-
a frame being configured so as to be removably securable to adjacent vertebrae; and
a pivot arm rotatably mounted to the frame. - View Dependent Claims (65, 66, 67, 68)
-
- 69. A spinal fixation kit comprising a cutting device and a fixation member, wherein the cutting device includes a cutting element that is moveable from a first position in which the cutting element is disposed within a housing of the device and a second position in which a portion of the cutting element is disposed outside of the device housing.
