Abstract

Instrumentation for implanting an artificial intervertebral disc includes static trials and a dynamic trial for determining the appropriate size of disc to be implanted, static trial holders (2060) for manipulating the static trials (1000), inserter/impactors for inserting and removing the static trials and for inserting the artificial intervertebral discs, repositioners/extractors for repositioning and extracting the static trials or the artificial intervertebral discs, and a leveler for setting the proper position of the artificial intervertebral disc. Methods for using the same are also disclosed. Features for artificial intervertebral discs and intervertebral spacer devices useful for manipulation by the instrumentation are also disclosed.

Claims (14)

1. A spinal orthopedic device and tool set, comprising:
an intervertebral spacer device having first and second baseplates mounted to one another such that the first and second baseplates are articulatable relative to one another, the first baseplate having a top surface and an opposed bottom surface, the bottom surface of the first baseplate having a perimetrical region including a plurality of recesses formed therein, the second baseplate having a top surface and an opposed bottom surface, the top surface of the second baseplate having a perimetrical region including a plurality of recesses formed therein, the perimetrical regions of the baseplates separated by a spacing having a first width, wherein the recesses of the perimetrical regions of the first and second baseplates include walls that define an access volume separated by a spacing having a second width greater than the first width; and a manipulation tool having a distal shaft having a relevant dimension greater than the first width, but less than the greater second width, such that when the distal shaft is accommodated between the perimetrical regions of the baseplates only in the access volume, movement of the intervertebral spacer device relative to the distal shaft of the manipulation tool is limited by interference between the distal shaft and the walls of the recesses, such that the intervertebral spacer device is manipulatable using the manipulation tool.
2. The spinal orthopedic device and tool set of claim 1, wherein the perimetrical regions have a plurality of opposing recess pairs.
3. The spinal orthopedic device and tool set of claim 1, wherein each access volume is aligned with a desired surgical approach direction.
4. The spinal orthopedic device and tool set of claim 3, wherein at least one of the surgical approach directions is an anterior approach direction.
5. The spinal orthopedic device and tool set of claim 4, wherein the perimetrical regions have three opposing recess pairs, each defining first, second, and third access volumes, respectively, each being aligned with an anterior approach direction, a left antero-lateral approach direction, and a right antero-lateral approach direction, respectively.
6. A spinal orthopedic device and tool set, comprising an intervertebral spacer device having first and second baseplates mounted to one another such that the first and second baseplates are articulatable relative to one another, the first baseplate having a top surface and an opposed bottom surface, the bottom surface of the first baseplate having a perimetrical region including a plurality of recesses formed therein, the second baseplate having a top surface and an opposed bottom surface, the top surface of the second baseplate having a perimetrical region including a plurality of recesses formed therein, the perimetrical regions of the baseplates separated by a spacing having a first width, wherein at least one recess of the first baseplate is opposed to a recess of thesecond baseplate such that the recesses define an access volume between the baseplates separated by a spacing having a second width greater than the first width;
and a manipulation tool having a distal shaft having a relevant dimension greater than the first width, but less than the greater second width, such that when the distal shaft is accommodated between the perimetrical regions of the baseplates only in the access volume, movement of the intervertebral spacer device relative to the distal shaft of the manipulation tool is limited by interference between the distal shaft and the walls of the recesses, such that the intervertebral spacer device is manipulatable using the manipulation tool.
7. The spinal orthopedic device and tool set of claim 6, wherein each access volume is aligned with a desired surgical approach direction.
8. The spinal orthopedic device and tool set of claim 7, wherein at least one of the surgical approach directions is an anterior approach direction.
9. The spinal orthopedic device and tool set of claim 8, wherein the at least one of the perimetrical regions has three recesses, each defining first, second, and third access volumes, respectively, each being aligned with an anterior approach direction, a left antero-lateral approach direction, and a right antero-lateral approach direction, respectively.
10. A spinal orthopedic device and tool set, comprising:
an intervertebral spacer device having first and second baseplates mounted to one another such that the first and second baseplates are articulatable relative to one another.
the first baseplate having a top surface and an opposed bottom surface, the bottom surface of the first baseplate having a plurality of first recesses formed therein, the second baseplate having a top surface and an opposed bottom surface, the top surface of the second baseplate having a plurality of second recesses formed therein, the plurality of first and second recesses each having a circular wall and a base, wherein at least one first recess of the first baseplate has a corresponding opposing second recess with that of the second baseplate; and a manipulation tool having a distal shaft configured to engage one of the at least one first recess of the first baseplate and one of the at least one corresponding opposing second recess of the second baseplate along an axis perpendicular to an axis along a length of the baseplates, such that when the distal shaft of the manipulation tool is so engaged, movement of the first baseplate with the second baseplate is limited by interference between the distal shaft and the recesses.
11. The spinal orthopedic device and tool set of claim 10, wherein the perimetrical regions have a plurality of opposing recess pairs.
12. The spinal orthopedic device and tool set of claim 10, wherein each access volume is aligned with a desired surgical approach direction.
13. The spinal orthopedic device and tool set of claim 12, wherein at least one of the surgical approach directions is an anterior approach direction.
14. The spinal orthopedic device and tool set of claim 13, wherein the perimetrical regions have three opposing recess pairs, each defining first, second, and third access volumes, respectively, each being aligned with an anterior approach direction, a left antero-lateral approach direction, and a right antero-lateral approach direction, respectively.
