Abstract
A system for stabilizing a cervical spine segment includes a pair of uncinate joint stabilizers for stabilizing a respective pair of uncinate joints. Each uncinate joint stabilizer is elongated along a lengthwise dimension and is configured for placement in the respective uncinate joint with the lengthwise dimension substantially oriented along an anterior-to-posterior direction of the cervical spine segment. Each uncinate joint stabilizer has height configured to define spacing of the respective uncinate joint. Each uncinate joint stabilizer includes a generally cylindrical portion with cylinder axis in the lengthwise dimension. The generally cylindrical portion has threads for threading the uncinate joint stabilizer into the respective uncinate joint along the anterior-to-posterior direction. The threads are interrupted by one or more fenestrations configured to accommodate bone graft material, bone growth, and/or tissue displaced from the respective uncinate joint by the uncinate joint stabilizer.
