In this video from the Journal of Neurosurgery, researchers present the case of a 53-year-old woman with “symptoms of both radiculopathy and myelopathy caused by a large, calcified disc herniation at C4–5.”

After four months of medical treatment and rehabilitation, she failed to improve, the JNS description states. “A single-level cervical disc arthroplasty was successfully performed with the ProDisc-C Vivo, DePuy Synthes), and her symptoms were completely ameliorated afterward. The follow-up images demonstrated preservation of motion at the indexed level.”
