Abstract
An intervertebral support assembly, comprising a pair of bone allografts positioned between two adjacent vertebrae, the bone allografts being positioned towards the anterior portion of the adjacent vertebrae; and a pair of facet screws, each facet screw securing together a facet joint between the two adjacent vertebrae. A method of providing support between two adjacent vertebrae, comprising positioning a pair of bone allografts between the two adjacent vertebrae at a location towards the front of the adjacent vertebrae; and securing together facet joints between the two adjacent vertebrae with a pair of facet screws.
Claims24
A method of providing support between two adjacent vertebrae, comprising:
- positioning a pair of allografts between the two adjacent vertebrae at a location towards the anterior portion of the adjacent vertebrae;
- and
- securing together facet joints between the two adjacent vertebrae with a pair of facet screws, wherein said facet screws are positioned in at least one of a transfacet and translaminar approach.
A method of providing support between two adjacent vertebrae, comprising:
- positioning a pair of bone allografts between the two adjacent vertebrae at a location towards the anterior portion of the adjacent vertebrae and at an angle to one another;
- and
- securing together facet joints between the two adjacent vertebrae with a pair of facet screws.
A method of providing support between two adjacent vertebrae, comprising:
- positioning a pair of bone allografts between the two adjacent vertebrae at a location towards the anterior portion of the adjacent vertebrae;
- securing together facet joints between the two adjacent vertebrae with a pair of facet screws;
- and
- positioning autologous bone graft material posterolaterally behind the bone allografts.
A method of providing support between two adjacent vertebrae, comprising:
- positioning a pair of bone allografts between the two adjacent vertebrae at a location towards the anterior portion of the adjacent vertebrae;
- securing together facet joints between the two adjacent vertebrae with a pair of facet screws;
- and
- positioning autologous bone graft material positioned between and to the rear of the bone allografts.
A method of providing support between two adjacent vertebrae, comprising:
- positioning a pair of bone allografts between the two adjacent vertebrae at a location towards the anterior portion of the adjacent vertebrae;
- securing together facet joints between the two adjacent vertebrae with a pair of facet screws;
- and
- harvesting autologous bone graft material from an iliac crest.
A method of providing support between two adjacent vertebrae, comprising:
- positioning a pair of bone allografts between the two adjacent vertebrae at a location towards the anterior portion of the adjacent vertebrae, wherein a first bone allograft is advanced into position between the two adjacent vertebrae through a first percutaneous cannula and the second bone allograft is advanced into position between the two adjacent vertebrae through a second percutaneous cannula;
- and
- securing together facet joints between the two adjacent vertebrae with a pair of facet screws.
