The Fixation Rail provides the stability for the Fixation Clamps. The 9mm diameter rail comes in lengths of 50mm, 75mm and 100mm. Drive Threads along the Fixation Rail engage the drive screw to secure the clamp as well as enable the clamp to exert a compressing or distracting force. The threaded hole at each end of the rail secures an end clamp and may be integrated into future development concepts.
