Method of spinal fixation using adhesive media
First Claim
Patent Images
1. A method for stabilizing a portion of the spine, comprising the steps of:
- accessing a first bony surface on a first vertebra, wherein the first vertebra comprises a vertebral body and at least one bony process;
accessing a second bony surface on a second vertebra, wherein the second vertebra comprises a vertebral body and at least one bony process; and
affixing the first bony surface and the second bony surface with an adhesive medium;
wherein the first bony surface and second bony surface of the affixing step comprise a zygapophyseal joint and wherein the affixing step comprises minimally invasively joining the first bony surface and the second bony surface and preserves the cortical bone about the first bony surface and second bony surface.

Abstract
Disclosed are methods of spinal fixation involving application of a liquid medium which cures, hardens, polymerizes or otherwise serves to bind adjacent vertebrae together. The fixation which results from this binding may be temporary or essentially permanent in duration, and may be used to treat conditions or disease of the spine, such as inflammation, instability or fracture. In a preferred embodiment, the liquid medium comprises a low viscosity cyanoacrylate-based adhesive.

13. A method for treating a patient, comprising the steps of:
-
accessing a first bony portion of a first vertebra, wherein the first bony portion is posterior to the vertebral body of the first vertebra; accessing a second bony portion of a second vertebra, wherein the second bony portion is posterior to the vertebral body of the second vertebra; engaging the first bony portion and the second bony portion with a medium at least at a zygapophyseal joint between a first bony surface and a second bony surface; and fixing the relative orientation between the first vertebra and the second vertebra by permitting physical or chemical transformation of the medium;
whereinthe engaging step comprises minimally invasively joining the first bony portion and the second bony portion. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A method of treating a spine, comprising the steps of:
-
accessing facet joint between a first facet on a superior articular process of a first vertebra and a second facet on a corresponding inferior articular process of a second vertebra; orienting the first vertebra and second vertebra; and filling at least a portion of the facet joint with a medium to secure the orientation between the first vertebra and second vertebra. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method of treating a spine, comprising the steps of:
-
minimally invasively accessing a zygapophyseal joint between adjacent vertebrae, the adjacent vertebrae comprising a superior vertebra with at least one inferior articular process and a inferior vertebra with a vertebral body and at least one superior articular process, wherein at least one inferior articular process of the superior vertebra corresponds to a superior articular process of the inferior vertebra; and positioning the adjacent vertebra from a first spatial orientation to a second spatial orientation; and securing the adjacent vertebrae in the second spatial orientation by engaging at least one superior articular process of one of the two adjacent vertebrae with the corresponding inferior articular process of the other of the two adjacent vertebrae using a medium at the zygapophyseal joint between the at least one superior articular process and the corresponding inferior articular process. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
