Abstract: Paget's disease of bone is a localised chronic osteopathy which produces bone deformities, bone hypervascularity, structural weakness and altered joint biomechanics. Although radiological diagnosis of Paget's disease of bone is usually straightforward, monostotic cases may potentially raise specific problems which require invasive and expensive procedures such as bone biopsies. The pelvis and upper femur are frequently affected, resulting in disabling hip disease that may require total hip arthroplasty. We report a case of Paget disease of bone in an 84-year-old woman, which was initially identified as avascular necrosis of the hip, reason for which she underwent total hip arthroplasty. During follow up, the patient complained about hip pain and in a few months she was not able to walk because of an early loosening with bone destruction. Radiological and laboratory exams were carried out with normal results except for alkaline phosphatase (AP). After treatment with biphosphonates hip pain relieved but hip reconstruction was not possible. In this paper we present an early aseptic loosening of hip arthroplasty due to monostotic Paget's disease of bone, a rare ethiology of loosening which poses particular diagnostic difficulties prompting an excessive use of excisional biopsies.
