Terri Wagner-Morley was so hopeful about her new right hip. It would ease her chronic arthritis pain, allow her to exercise, even help her lose a little weight. She had a DePuy metal-on-metal ASR hip implanted in 2008 and, at first, it worked just like she'd hoped. Then she began feeling a "pop" in the hip. The pop turned to pain, making it hurt to move. …Minnesota's renowned Mayo Clinic has dramatically curtailed its use of the metal devices. Dr. David Lewallen, a Mayo orthopedic surgeon, said more data on metal-on-metal hips needs to be gathered, saying they remain a viable option for some patients. But he acknowledged the array of concerns. "That continues to be a mystery, what is going on in these patients," he said. "And that continues to be the ongoing mystery and the focus of investigation and work now."
