There is a current fear in the medical community that hip replacements that work by having metal on metal might be dangerous. Currently, advice is being drawn up for over 30,000 people in the UK who have been given hip replacements of this type.
Despite the news that these replacements might be more dangerous than previously thought, medical authorities have stated that most people have a very low risk of actually developing any problems from their new hip.
The concerns about the metal hips have come to light after Margaret Davie, a woman to receive a Pinnacle replacement hip at Hartlepool hospital, has claimed that the device has ruined her health. The company who manufactured her hip have accepted no liability but they’ve previously had to recall another artificial joint that they produced.
This latest report fuels a growing belief in the medical community that certain replacement joints can cause bone and tissue damage. The previous hip joint they recalled was called the ASR and it soon became clear that the device had a failure rate of nearly 15 percent. Since the initial recall though further evidence has shown that the failure rate of this replacement joints could be as high as 50 percent, just six years after the initial surgery.
Mrs Davie was caused so much discomfort by her metal replacement hip that she had it removed and a new one made out of ceramic put in. This failed to help her condition however and she suffered a dislocation of a hip and is now back in hospital.
The problem with all metal hip replacements is that the metals can rub against each other and cause fragments of metal to break off and into the bloodstream. This can potentially cause poisoning and also damaged bone and muscle.
