Patent ID: 8366775

Claim:
A spinal orthopedic device and tool set, comprising: an intervertebral spacer device having a first baseplate and a second baseplate, the first and second baseplates each including an upper surface, a lower surface, and an angled perimeter, the first and second baseplates mounted to one another such that the first and second baseplates are articulatable relative to one another; and a manipulation tool having a correspondingly angled distal surface, such that when the correspondingly angled distal surface of the manipulation tool is engaged with the angled perimeter of at least one of the baseplates, rotation of the baseplates relative to the correspondingly angled distal surface of the manipulation tool is prevented by interference between the angled perimeter of at least one of the baseplates and the correspondingly angled distal surface of the manipulation tool, the manipulation tool further including a spacer protruding outwardly from the angled distal surface, the spacer having an upper angled surface and an lower angled surface, wherein the angled distal surface of the manipulation tool is engageable with the angled perimeter of at least one of the baseplates in a plurality of locations, each of the plurality of locations establishing a respective desired surgical approach angle for manipulating the intervertebral spacer device, and wherein when the manipulation tool is engaged to the baseplates in any one of the plurality of locations, the first baseplate is lordodically angled with respect to the second baseplate as the lower surface of the first baseplate is held against the upper angled surface of the spacer and the angled perimeter of the second baseplate is parallel with respect to the angled distal surface of the manipulation tool as the angled perimeter of the second baseplate is held against the angled distal surface of the manipulation tool.
