![]() What is Cobalt Poisoning?Īlso called “cobaltism” or “metallosis,” cobalt poisoning is a form of tissue destruction caused by excess cobalt and chromium in the body’s blood and tissue. ![]() We will fight to ensure that you and your family get the compensation you are owed. If you suspect that you or someone you love is experiencing negative consequences from a metal-on-metal hip replacement, the experienced medical device defect attorneys at Morris Law Firm are ready to help. If you or someone you care about has a metal-on-metal hip implant, it is vital to watch out for the warning signs of cobalt poisoning and to get periodic checkups and blood tests to check for excess cobalt ion levels and negative side effects. In the most severe cases, patients can be left permanently blind, deaf, or facing other conditions such as degenerative heart disease and memory loss. Excess cobalt toxicity can cause severe pain, bone and tissue death, and other serious symptoms. Increasing levels on serial review should also prompt referral to the treating surgeon for further investigation and review.Cobalt Toxicity & Cobalt Poisoning Cases: Los Angeles & NationwideĬobalt poisoning is a severe and dangerous side effect of metal-on-metal hip replacements. Many people with MoM THRs and high cobalt levels have fully functioning athroplasties and no signs or symptoms of toxicity.Ĭurrent guidelines suggest referring people with a cobalt level > 340 nmol/L, with or without symptoms, to their orthopaedic surgeon. Consequently there is a lack of consensus worldwide regarding the safe level of metal ions in the bloodstream, and more research is required to establish the levels at which the presence of metal ions causes toxicity. The essential link between symptoms and peak metal ion levels, or the length of exposure to these ions, remains unclear. When presented with a seemingly disparate cluster of symptoms, it may be difficult to identify metal ion toxicity as a potential precipitating cause, even in people who have had MoM THR. Signs of cobalt–chromium toxicity - advice for GPsĬobalt–chromium toxicity produces a symptom complex that may include neurosensory, endocrine,respiratory, neurocognitive, cardiac and neurological symptoms, such as loss of auditory and visual acuity. MDA/2010/033: If metal ion levels in whole blood are elevated above 120 nmol/L (cobalt) or 135 nmol/L (chromium), a second test should be performed three months after the first in order to identify patients who require further surveillance, which may include cross sectional imaging. ![]() Patients with high serum cobalt concentrations who undergo revision surgery with ceramic-plastic revisions experience a rapid fall in serum cobalt and significant improvement in neurological and cardiovascular function. Serum reference ranges for cobalt and chromium are 0–20 nmol/L and 0–100 nmol/L, respectively. Pathology laboratories are reporting an increasing number of people who have had an MoM THR with very high serum cobalt concentration (>1000 nmol/L). When cobalt was used to treat refractory anaemia in patients in the 1960s, symptoms of cobaltism were described and subsequently confirmed to include neurological, cardiac and endocrine symptoms. While both chromium and cobalt ion levels are elevated in patients with MoM implants, cobalt is the most important contributor to metal ion toxicity. Note MHRA has updated its alert as of June 2012 Please note the hip replacement monitoring service is currently only available by referral to the Orthopaedic surgeons at the RDE. Sample is a trace element free tube (Sodium Heparin). Monitoring for potential toxicity in patients with metal on metal hip protheses Blood Sciences Test
