Published: May 16, 2011

"The FDA is aware of public health questions regarding the safety of metal-on-metal (MoM) total hip replacement (THR) systems," FDA public information officer Amanda Sena tells WebMD in an email exchange. The most disturbing of these questions concern reports of "a small number of patients who may have developed symptoms or illnesses elsewhere in the body (systemic effects), including effects on heart, nervous system, and thyroid gland," according to Sena.
