Abstract

A spine stabilization system includes a flexible member attachable to a portion of the spinal column. The member includes components that are oriented and function similar to the natural fiber orientation of the anterior longitudinal ligament and annulus tissue. The use of components resist loading applied by extension and rotation of the spine, while the flexibility of the member does not subject it to the compressive loading of the spinal column segment to which it is attached.

Independent Claims | See all claims (20)

  1. 1. A spinal stabilization device, comprising: a flexible member having opposite edges spaced from one another along an axis with a length sized for attachment between first and second vertebrae, said flexible member including a mesh pattern comprising a first layer including a number of square shaped apertures along the axis extending through said first layer and a second layer including a number of diamond shaped apertures along the axis extending through said second layer, wherein said diamond shaped apertures include sides obliquely oriented to said axis of said flexible member and said square shaped apertures include sides paralleling said axis of said flexible member.
  2. 8. A spinal stabilization device, comprising: a flexible member having opposite ends spaced from one another along an axis with a length sized for attachment between first and second vertebrae, said flexible member including a mesh pattern comprising a single layer including a number of openings extending therethrough between opposing surfaces, at least a portion of said number of openings being defined by at least one of a plurality of vertical components of said mesh pattern extending along said axis and at least one of a plurality of first diagonal components of said mesh pattern that are obliquely oriented to said axis and said vertical components.
  3. 15. A device for spinal stabilization, comprising: a first member extending along a longitudinal axis between opposite first and second ends, said first and second ends being spaced by a length sized for attachment to first and second vertebrae; a second member extending along said longitudinal axis between opposite first and second ends, said first and second ends being spaced by a length sized for attachment to first and second vertebrae, wherein said first and second members are spaced from one another on opposite sides of said longitudinal axis; at least one diagonal member obliquely oriented to said longitudinal axis and extending between said first end of said first member and said second end of said second member; and a first fastener extending through said diagonal member and said first end of said first member and a second fastener extending through said diagonal member and said second end of said second member.
