Posterior Spinal fusion to treat thoracolumbar pathologies has been performed since the early 1900’s and continues to evolve today. The desire for improved patient outcomes and enhanced surgical experience has continued to drive innovation in this segment of spinal surgery. Today’s spinal fixation systems are more advanced than ever, and require increased mechanical advantage, simplified instrumentation, a better anatomical fit, and the necessary strength to achieve a solid fusion. Alphatec strives to move spinal fixation forward and continues innovation by further enhancing the surgeon and patient surgical experience. The Arsenal Degenerative spinal fixation system was thoughtfully designed to provide operational efficiency, biomechanical strength, and surgical simplicity while providing a complete solution to combat most complex degenerative pathologies. The combination of low profile implants, intuitive instrumentation, and proven strength are certian to quickly become allies.
