Fluordeoxyglucose positron emission tomography detection of inflammatory reactions due to polyethylene wear in total hip arthroplasty.
A patient experienced chronic pain 8 years after total hip arthroplasty. Radiology and bone scanning showed no signs of aseptic loosening, but fluorine-18 fluorodeoxyglucose positron-emission tomography ((18)F-FDG-PET) showed intensive glucose metabolism in the joint capsule and around the prosthesis neck. The surgical intervention revealed soft tissue reaction in this area. Histologic examination showed a granulomatous foreign body reaction against polyethylene debris particles. Infection and rheumatoid arthritis could be excluded clinically, histologically, microbiologically, and with the bone scan. Therefore, FDG-PET detected inflammatory reaction caused by polyethylene wear in total hip arthroplasty and allowed clinicians to decide on interventions, including removal of granulomatous tissue and the replacement of worn artificial joint components to prevent aseptic loosening.
