Abstract
Presently disclosed is a spinal implant. In an embodiment, a spinal implant includes a porous body configured to promote bone growth. The porous body may have an attachment portion that is configured to secure the spinal implant to a fixation system attached to one or more vertebra. The porous body may also include a fusion plate extending from the attachment portion and configured to contact transverse processes, lamina, or facet of adjacent vertebrae. Accordingly, when the attachment portion is secured to the fixation system, the fusion plate may be maintained in compression against the transverse processes, lamina, or facet.
Claims27
A spinal implant system comprising:
- a pair of bone fasteners configured to be fixed to adjacent vertebrae of a spine;
- a rod extending between and secured by the pair of bone fasteners;
- and
- a spinal implant having a porous body configured to promote bone growth, the body having:
- an attachment portion configured to extend at least partially around the rod between the pair of bone fasteners to secure the spinal implant to the rod, and
- a fusion plate extending from the attachment portion and offset from the attachment portion, the fusion plate configured to contact unilateral transverse processes or lamina of the adjacent vertebrae longitudinally along the spine, such that when the attachment portion is secured to the rod, the fusion plate is maintained in compression against the transverse processes or lamina.
A spinal implant comprising:
- a porous body configured to promote bone growth, the body having:
- an attachment portion configured to secure the spinal implant to a fixation system attached to one or more vertebra of a spine, and
- a fusion plate extending from the attachment portion, and offset from the attachment portion configured to contact unilateral transverse processes or lamina of adjacent vertebrae longitudinally along the spine, such that when the attachment portion is secured to the fixation system, the fusion plate is maintained in compression against the transverse processes or lamina;
- wherein the fusion plate further has a convex lower surface, and has a plurality of protrusions on the convex lower surface configured to promote contact with the transverse processes or the lamina of the adjacent vertebrae.
A spinal implant comprising:
- a porous body configured to promote bone growth, the body having:
- an attachment portion configured to secure the spinal implant to a fixation system attached to one or more vertebra of a spine, wherein the attachment portion includes a hook configured to extend at least partially around a rod between a pair of bone fasteners of the fixation system;
- and
- a fusion plate extending from the attachment portion, and offset from the attachment portion configured to contact unilateral transverse processes or lamina of adjacent vertebrae longitudinally along the spine, such that when the attachment portion is secured to the fixation system, the fusion plate is maintained in compression against the transverse processes or lamina.
