Abstract: A retractor includes a first arm, a second arm, and a translating member. The first arm comprises a proximal portion configured to retain a first retractor member and a distal portion configured to rotate relative to the proximal portion about a first axis. The second arm is configured to retain a second retractor member, such that rotation of the distal portion about the first axis causes the first retractor member to pivot toward or away from the second retractor member when the first retractor member and the second retractor member are coupled to the first arm and the second arm, respectively. The translating member is coupled between the proximal portion and the distal portion, and is configured to receive a drive force that causes the translating member to bias the distal portion to pivot relative to the proximal portion about the first axis.

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.

Abstract: Provided are fixation members useful in fixing an implant to a bone. The fixation members include an awl tip so as to enable their secure installation by use of an awling motion, which in turn speeds the installation of the fixation members.
