I'm 95% sure that this is the episode i watched a few years ago that discusses ADR (Charite) vs. Fusion and features 2 patients who were in the randomized study.
Or it's possible that this is a new episode with new patients. Nonetheless the show description mentions “patients with severe back problems”.

Its called “Bionic Back” on the Discovery Health Channel at 5 and 8 pm (here in pst), and again on Sunday at 12 noon.
