Denver Woman Allergic to Hip Implant
Published at
National Jewish Health(DENVER) — When Paula Spurlock started to experience itching and pain all over her body, she never dreamed that she was allergic to the metal device implanted into her hip.
Spurlock, 50, experienced migraines, itching and pain for nearly two years before doctors noticed that her right hip lit up on a PET scan. It was the hip that had a metal joint implanted in 2008.
“My entire body itched,” she told ABC News. “A regular allergist did some testing that didn’t show anything. Not one person along the way said, ‘I wonder if you’re allergic to your hip.'”
Once her PET scan hinted at a problem with the hip, Spurlock started seeing Dr. Karin Pacheco, an allergist at National Jewish Health in Denver. Pacheco said she administered skin patch tests, which took two days to process and involved looking for an immune system response to the metals and other materials in the artificial joints.
“What was really interesting about her was that she actually had both hips replaced, but they were made of different metal alloys,” Pacheco said. “She was allergic to the one but not the other.”
Specifically, Spurlock learned for the first time that she had a cobalt allergy, though she’d never experienced metal allergy symptoms before. Her titanium hip didn’t cause any problems.
Spurlock said she learned that the cobalt hip became defective about two years after doctors implanted it, causing it to produce tiny metal shavings as she moved. Those spread to Spurlock’s bloodstream and caused the allergic reaction, she said. (The replacement hip has not been recalled.)
Doctors removed Spurlock’s right hip and replaced it with a ceramic hip. Now, she says she is symptom-free. She said she hopes people can learn from her experience and get tested before surgery.
“There’s nothing worse than wanting to just crawl out of your skin because the itching is so bad,” she said.
