Abstract
An anterior thoracic/lumbar system comprising a thin plate and fasteners for securing the plate to vertebrae or other osseous material. The plate may be hinged along the central axis, with a pair of collinear holes on each portion of the plate. Each of the holes accommodates a bolt which is screwed into the vertebrae and secured to the plate using a nut.
Claims106
A method of performing spinal fusion surgery, comprising:
- inserting an implant between a first vertebral body and a second vertebral body;
- hingedly coupling a first plate having a first pair of openings with a second plate having a second pair of openings;
- and
- affixing said hingedly coupled first and second plates to said first and second vertebral bodies.
A method of affixing a first vertebra to a second vertebra, each vertebra bisected by a lateral axis so as to include a posterior region and an anterior region, the method comprising:
- providing a first plate having a first pair of openings hingedly coupled to a second plate having a second pair of openings;
- and
- affixing said first and second plates to said first and second vertebrae such that said first plate is disposed at least in part within said posterior region of at least one of said first and second vertebrae, and such that said second plate is disposed at least in part in within said anterior region of at least one of said first and second vertebra.
A system for performing spinal fusion surgery, comprising:
- an implant dimensioned for use in spinal fusion surgery;
- a first plate having a first pair of openings and a second plate hingedly affixed to said first plate and having a second pair of openings;
- and
- a plurality of bone anchor elements, one for each of said first pair of openings and said second pair of openings to anchor said first and second plates to vertebrae in the spine.
A system for affixing a first vertebra to a second vertebra, each vertebra bisected by a lateral axis so as to include a posterior region and an anterior region, the system comprising:
- a first plate having a first pair of openings hingedly coupled to a second plate having a second pair of openings, wherein said first plate is disposed at least partially within said posterior region and said second plate is disposed at least partially within said anterior region;
- and
- a plurality of bone anchor elements, one for each of said first pair of openings and said second pair of openings to anchor said first and second plates to vertebrae in the spine.
