Abstract
A system and method of bone fixation are provided for improving the bone growth and stability of the fixated bones. For example, a target site for a bone fixation procedure can be accessed at a facet of a first vertebra using a tissue dilator. Bone material can be disrupting from or at the target site, and a bone fixation device can be installed to fix the first vertebra relative to a second vertebra. The disruption and/or removal of the bone material, such as by rasping facets or a facet joint of the first vertebra and the second vertebra, can tend to promote bone growth. Further, it is contemplated that bone graft material can be inserted at the target site, such as into a joint space formed between facets of the first vertebra and the second vertebra.
