Abstract
A fixation system may comprise at least one carriage element being capable of receiving one or more bone fasteners, the carriage element being mountable on a plate, the plate having an engaging portion for adjustably securing the carriage element to the main plate, the engaging portion allowing translational movement of the carriage plate with respect to the plate in only one axial direction. In one embodiment, the plate includes arms for receiving the carriage element and the carriage element includes channels mountable on the arms, with the engaging portion disposed within the channels. A method of use and kit is also described.
