When the tiny chromium and cobalt ions reach the bloodstream, symptoms of metal toxicity or metal poisoning can occur. What Are the “Typical” Symptoms of Cobalt Poisoning? If you wonder whether your Pinnacle hip implant may be responsible for metal poisoning, check out the symptoms below. The Pinnacle has been shown to have high failure rates, with many recipients having been required to undergo revision surgery within five years of the initial implant. The metal liner used in the Pinnacle is known as the Ultamet, however the Pinnacle did not actually gain FDA approval to use a metal liner with the Pinnacle hip system. Unlike the ASR, the Pinnacle is attached to the bone via screws. The Pinnacle implements a separate plastic or metal liner which is placed on top of the femoral head. What this means to the implant recipient is that the design implements a single one-piece ball and cup which is fitted onto the top of the stem. The Pinnacle and ASR are both considered monoblock design, although the ASR is more of a “hybrid” monoblock. The Pinnacle was the predecessor to the ASR which received FDA approval in 2005. The DePuy Pinnacle gained FDA approval in 2000, and although it has yet to be recalled like the DePuy ASR, there have been a significant number of adverse reports of failure and metal toxicity. Failure of the implant will necessitate a revision surgery in which the Pinnacle (or the metal liner) is removed and replaced with non-metal components.ĭid the DePuy Pinnacle Cause Your Symptoms of Chromium Poisoning? Total failure of the implant can be the result of these adverse reactions to a DePuy Pinnacle metal hip implant. Inflammation ensues which leads to chronic pain, tissue damage and death and even bone loss. Unfortunately, the body’s natural defenses are no match for cobalt and chromium metals. When the metal shards burrow into the hip tissues, the body sees these metal ions as intruders and sends special white cells to fight them off. This friction releases microscopic metal ions into the body which will either travel into the bloodstream or will become lodged in the surrounding tissues. In the all-metal hip implants-or the implants which utilize a ceramic ball yet still use a metal liner-when the implant recipient engages in activity, the metal components rub against one another, creating friction. If you are the recipient of a metal-on-metal hip implant, you may have been exposed to cobalt and chromium metals accumulating in your body.
