It was reported that a patient became infected and had the hip irrigated and debrided on an unknown date.
The patient received antibiotics for 6 weeks.
Then the patient was revised approximately one year later.
Findings at the time of the revision were: stem was well positioned and fixed, acetabular shell was fixed, steep and overly and anteverted, head adapter was cold welded to the stem trunnion so large head was first separated from the adaptor so the taper adaptor can be removed.
The articular surface of the head shows severe corrosion as well as high cobalt levels.
