This article describes a new mechanism of failure of a ceramic-on-ceramic total hip arthroplasty (THA) due to fretting corrosion and failure of the Morse taper. A 46-year-old man with hip osteonecrosis underwent THA in 2006. A ceramic-on-ceramic, un-cemented THA with a titanium femoral component and metal-on-ceramic Morse taper was implanted. Two years postoperatively, he presented with swelling in his groin and a painless medial thigh mass. The thigh mass was diagnosed as an abscess. Incision and drainage was performed and resulted in a sinus tract that continuously drained copious amounts of seropurulent fluid. Two months later, the patient underwent irrigation, debridement, and explantation of his hip. Frozen sections showed no signs of infection. There was dramatic visible wear of the Morse taper and pieces of metal embedded in the ceramic. Permanent sections showed chronic inflammation and foreign body reaction. He subsequently underwent an uneventful re-implantation with a metal-on-highly-cross-linked-polyethylene THA. In this case, failure of the morse taper led to metal debris, which reacted with the ceramic and caused dramatic third-body wear. The thigh mass, which appeared to be an infection, proved to be a massive foreign body granuloma. Malfunction of the morse taper as reported in this case represents a possible failure mechanism of a ceramic-on-ceramic THA.
