Supplemental spine fixation device
First Claim
1. An implant for rigidly positioning spinous processes comprising:
- a first means adapted for engaging a first spinous process;
a second means adapted for engaging a second spinous process;
a body means adapted for positioning between the first spinous process and the second spinous process;
a hub means for engaging the first means, the second means and the body means; and
wherein said body means is rotatable, and pivotable relative to the hub means.

Abstract
A supplemental spine fixation device and method is used in association with a primary spine fixation device. The supplemental spine fixation device includes a guide and spacer for distracting apart adjacent spinous processes and the device has hook members which hook about the first and second spinous processes. With the spinous processes distracted and the hook members about the spinous processes, the hook members can be rigidly secured to a hub in order to rigidly affix the spinous processes about the spacer. The rigidity between the spinous processes assures that the vertebral bodies will be held rigidly in place in order to promote bone growth and fusion. Further additional freedom of movement between the spacer and hub is accomplished with the spacer being pivotably mounted relative to the hub. The hooks have a tissue distracting lead-in guide for allowing the hooks to be easily urged between spinous processes.
