I was concerned about longevity with the flexible core of the CP-ESP and LP-ESP. This 2012 study got me to commit to cervical ADR with the CP-ESP. 40 million deflection cycles in each of 3 axes on one test unit without any degredation of performance. My surgeon Dr. Desai says that in the unlikely case of core failure, he can chip out the ADR and install a new one.
