Abstract
A trialing and preparation system for preparing a disc space between two adjacent vertebrae is provided. The system includes a guide shaft, a trialing cage or spacer, a scraper and a driving shaft. The guide shaft supports the trialing spacer within the disc space and may include an angular adjustment for such access. The scraper sleeves over the guide shaft into an abutting relationship with the adjacent vertebrae. The driving shaft is coupled to the scraper by a pivoting and reciprocation mechanism that allows angular adjustment of the scraper. Also, reciprocation of the driving shaft reciprocates the scraper through a limited sweep of motion to remove osteophytes from the vertebrae.
