If you have any interest in artificial hips, you need to follow the work of Dr. Steven Tower. An orthopedic surgeon in Anchorage Alaska, Dr. Tower has built a one-man research laboratory studying the horrifying health effects of chrome and cobalt hip components. While hip manufacturers have been slow to produce meaningful studies on the ill-effects of metallosis on the human body, Dr. Tower decided to study his own patients. What he discovered could save lives.

Dr. Tower’s Backstory

Orthopedic Surgeon Steven TowerSteven Tower’s story is remarkable. He is featured in the Netflix medical device documentary The Bleeding Edge. Dr. Tower is an avid cyclist and needed a hip replacement several years ago. He chose the DePuy ASR metal-on-metal artificial hip because it was marketed to “exceptionally active individuals.” Several months after his hip replacement surgery, however, Dr. Tower noticed a tremor in his hand. His ears started ringing, his thinking became confused and he began repeating himself when he spoke. One night while attending a medical conference Dr. Tower had a mental breakdown and trashed his hotel room. He wrote all over the walls with sharpies and pens, and wrote on the hotel mirrors with soap. When he returned home he measured the metal levels in his blood, and the test results revealed 100 times the normal amount of cobalt that should be in his body. Dr. Tower soon arranged to have his metal hip components removed in a revision surgery. Within a month his thinking cleared and his other symptoms mostly disappeared. He was relieved, but also intrigued.

For many years my clients with failing artificial hips have asked me about the health effects of high cobalt and chromium levels in the body. These questions usually arise after clients get blood work done and the test reveals abnormally high metal levels. If you are reading this article, you probably already know that cobalt and chromium are two metals used in the construction of most metal-on-metal (MoM) artificial hip systems. In fact, cobalt and chromium are used to make artificial hips that are not metal-on-metal but instead use polyethylene liners, or ceramic heads, or other non-metal components. When metal components grind together, as they naturally do when a MoM artificial hip is implanted in a person, very small metal particles can be released into the tissue and the bloodstream. I wrote about the health effects of metallosis on the body over a year ago. You can check out that article here.

Cobalt poisoning from artificial hip implants
Dr. Steven Tower, an orthopedic surgeon in Alaska, recently gave a fascinating (and alarming) talk about the many neurological problems he has observed in hip patients with elevated cobalt levels in the body. For years the focus following hip replacement surgeries has been on the physical condition of the hip itself. Dr. Tower has concluded that this approach is wrong, or at least incomplete, and he has seen that often the first signs of trouble with hip replacement patients are neurological symptoms. He has even given it a name: Arthroplasty Cobalt Encephalopathy, or ACE.

Cobalt and Chromium from metal-on-metal hip implants
Over the years I have worked with many people who had hip replacement surgery. Many of these clients discovered high metal levels in their bodies from metal-on-metal (MoM) hip components. Often the person would let me know that she had her metal levels checked and that the blood work came back with abnormally high readings of cobalt, chromium, or other metals. Still, the treating physician would occasionally dismiss the blood work results. At least one doctor told a patient, “no one knows the effects of higher metal levels on the body. We haven’t studied the impact of metallosis sufficiently. It is nothing to be worried about at this point.”

Sadly, this isn’t true. And it’s not the best medical advice. There have been several studies over the years that looked at metallosis in the body derived from metal-on-metal hip components. The first incident of metallosis from MoM hip implants was reported in 1971. Since then, doctors have been reporting the higher incidence of metallosis in patients who received MoM artificial hip implants. Several scholarly studies have been conducted, including a recent one whose results were published this month examining the impact of metallosis on the cells of patients.
