Following the August 26, 2010 recall of the DePuy ASR hip implants, individuals who underwent hip replacement arthroplasty have sought medical advice to determine whether their recalled ASR hips are failing.  In addition to those who received an ASR metal implant, patients who underwent total hip replacement surgery are experiencing similar Pinnacle problems.  Although common ASR and Pinnacle problems include popping, hip replacement pain, grinding and inflammation in the hip area, a silent symptom of hip replacement failure is cobalt poisoning or cobaltism.  Cobalt poisoning is particularly distressing because symptoms of poisoning can take time to manifest.  Individuals suffering from cobaltism may also have elevated levels of chromium, another type of metal poisoning.

ASR And Pinnacle Problems Include Chromium And Cobalt Poisoning

Since a metal implant is a metal-on-metal device, a patient who underwent hip arthroplasty and received either the ASR or Pinnacle metal implant is susceptible to metal poisoning.  Symptoms of poisoning include elevated levels of chromium or cobalt in the bloodstream, indicating that the patient is suffering from metal poisoning.  For example, a healthy individual typically has less than 1 microgram of cobalt in the bloodstream.  Individuals with cobalt poisoning have more than 7 micrograms of cobalt in their bloodstream.  Cobalt poisoning is toxic and can lead to metallosis, which occurs when metal particles and debris shed from the DePuy metal implant and enter the bloodstream.  Although metal poisoning is a strong indicator of hip replacement failure, without a blood test, it can easily go unnoticed.  Therefore, it is important for  individuals who received a DePuy Pinnacle or ASR metal implant to visit the doctor and undergo a full range of testing to determine whether they have chromium or  cobalt poisoning and are experiencing hip replacement failure.  In addition to a blood test, an MRI may also be indicated to aid in determining the extent of the ASR and Pinnacle problems stemming from the hip arthroplasty.  Complications arising from chromium, cobalt poisoning and metallosis can affect the nervous system, heart and thyroid gland.  Specifically, cobalt poisoning can result in tinnitus, vertigo, deafness, blindness, optic nerve atrophy, convulsions, headaches, peripheral neuropathy, cardiomyopathy, and hypothyroidism.
