Faulty medical implants investigation: I feel as if I'm 80, says mother, 41 Susanna Derham, 41, a mother-of-four, said the damage has left her in agony and feeling like an 80-year-old. She was 34 when she began to suffer from symptoms of arthritis, causing serious pain. Doctors were not sure why she was suffering at that age, but surgeons at East Surrey Hospital said they had a "great hip" for her. In 2006 she underwent a full replacement on the left side. At first, she was happy with the DePuy device. In 2010, just weeks after being told of a recall of the devices, she began feeling increasing levels of pain. Tests carried out last year revealed tissue damage surrounding the hip and high levels of cobalt and chromium ions in the blood. She has had corrective surgery but the pain has forced her to give up work and exercise. "I don't know if I ever will totally recover from this," she said. It's worrying and you just don't really know what the future holds for you. Mrs Derham, from Horley in Surrey, is among 120 cases being handled by the legal firm Gregory Abrams Davidson.
