This case involves a 70 year-old woman with a history of rheumatoid arthritis who used the Zimmerman hip device after she fell at her home and dislocated her hip. After assessing her condition, the doctor decided a hip replacement was her best option. The operation went well and the patient was allowed to leave after four days. However, she soon started to experience pain and swelling in her hip area but did not inform her doctor until the pain became severe. A later evaluation showed she had developed metallosis since receiving the Zimmer hip replacement. She subsequently questioned the safety and regulations used for the Zimmer hip.
