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. With such an arrangement, additional force is placed on vertebral bodies in order to encourage fusion. In additional, 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.
