Method and system for trans-lamina spinal fixation

摘要

A method of providing spinal stabilization is provided herein. More specifically, the method includes positioning a plurality of fixation assemblies within a plurality of vertebrae in a trans-lamina orientation wherein each fixation assembly includes a proximal portion configured to securely receive a stabilization element (e.g., a stabilization rod). The proximal portions of the various fixation assemblies can be aligned so as to secure at least one stabilization element in a desired position (e.g., along and above a midline of the patient's spine, adjacent and parallel to the midline). A system for providing spinal stabilization is also provided which utilizes trans-lamina delivery and positioning of fixation assemblies within target vertebrae thereby providing stronger fixation and a significant reduction in associated tissue damage.

主权项

1. A method of providing spinal stabilization, comprising:
inserting a first fixation assembly within a first vertebra, the first fixation assembly having a proximal receiving head and a bone-engaging portion; inserting a second fixation assembly within a second vertebra, the second fixation assembly having a proximal receiving head and a bone-engaging portion; positioning a spinal stabilization element within the proximal receiving heads of both the first and second fixation assemblies; and securing the spinal stabilization element within each of the proximal receiving heads; wherein, when each of the first and second fixation assemblies are inserted within the vertebra, the bone-engaging portion of each of the first and second fixation assemblies is angled away from a spinal canal extending, respectively, through the first and second vertebra, and the proximal receiving head of each fixation assembly is positioned along and above a midline of a patient's spinal column.
