The DePuy Pinnacle is a metal on metal hip replacement system: the ball and socket of the device are made of metal. Nowadays, the words "metal on metal" are enough to trigger a worried response from individuals implanted with these types of hips. And rightfully so.
With metal on metal implants, like the DePuy Pinnacle, the metal ball and metal socket rub against each other during activities. Metal is also released from implant parts where two components connect. Metal release results in metal ions to wear off the device causing damage to bone and soft tissue surrounding the implant and joint. This is known as an adverse local tissue reaction or adverse reaction to metal debris.
Adverse reaction to metal debris can cause pain, device failure, and implant loosening which may lead to needing a revision surgery. When metal ions are released into the bloodstream, it can precipitate a systemic reaction and cause other issues including skin rash, cardiomyopathy (a heart condition), neurological impairment, psychological changes, and thyroid abnormalities. The long term effects of exposure to these metal devices is unknown.
We highly recommend you speak to a doctor immediately if you have a DePuy Pinnacle whether or not you are experiencing the aforementioned symptoms. Get in touch with a lawyer since you are potentially entitled to reimbursement for problems relating to the DePuy Pinnacle.
