Abstract
A spinal implant provides supplemental and dynamic fixation and/or stabilization of the spine via connection to one or more existing or new spinal fixation and/or stabilization spinal constructs. The supplementary spinal fixation/stabilization implant has a first attachment device configured to couple to an existing or new spinal fixation/stabilization construct and a second attachment device configured to couple to the existing or new spinal fixation/stabilization construct at a second location. The first and second attachment devices are joined to each other via a resilient connector that allows dynamic movement between the first and second attachment devices.
Claims20
A spinal implant comprising:
- a first connector configured for attachment to a first spinal implant construct affixed to a lateral side of a spine;
- a second connector configured for attachment to a second spinal implant construct affixed to the lateral side of the spine;
- and
- a resilient connection member coupled to and between the first and second connectors, the resilient connection member allowing movement of the first and second connectors relative to one another.
The spinal implant of claim 2, wherein the resilient connection member is formed of an elastomeric.
A dynamic spinal implant comprising:
- a first connector configured for attachment to a first existing spinal implant construct affixed to a lateral side of a spine;
- a second connector configured for attachment to a second existing spinal implant construct affixed to the same lateral side of the spine;
- and
- a resilient connection member coupled to and extending between the first and second connectors, the resilient connection member allowing limited movement of the first and second connectors relative to one another.
A spinal implant for providing supplementary fixation or stabilization between adjacent fixed or stabilized levels of the spine, the spinal implant comprising:
- a first connection device configured for attachment to a first existing spinal implant construct affixed to a lateral side of first and second adjacent vertebrae of a spine;
- a second connection device configured for attachment to a second existing spinal implant construct affixed to the same lateral side of a third vertebra the spine adjacent one of the first and second vertebrae;
- and
- a resilient connection member formed of an elastomeric and coupled to and extending between the first and second connectors, the resilient connection member allowing limited movement of the first and second connectors relative to one another.
