As a condition of approval, Synthes Spine is required to conduct a five-year study assessing the long-term safety and effectiveness of the disc. The study will include the 286 patients who participated in the pre-approval clinical trials. The company is also required to complete an annual analysis and report any major adverse events (such as implant breakage, subsidence or expulsion from the disc space). These conditions are similar to those imposed on the Charite artificial disc. Zigler is himself responsible for publication of the national data now that the ProDisc-L has been FDA-approved.
