Fig. 1.
61-year-old woman who underwent bilateral resurfacing arthroplasty using Birmingham hip components (Smith & Nephew), reportedly 6 years previously on right and 3 years previously on left.
A, Anteroposterior radiograph shows no abnormalities.
B and C, Coronal multiacquisition variable-resonance image combination (MAVRIC) inversion recovery (B) and MAVRIC proton density–weighted (C) MR images show posterior column osteolysis on right (black arrows). Note thickened inferomedial synovial lining on right (arrowheads), indicative of adverse tissue reaction. On left, there is thinner synovial reaction with low-signal-intensity debris, indicative of metallosis (white arrows).

D, Coronal fast spin-echo MR image shows abductors, but adverse local tissue reaction occurring in inferomedial recess and acetabular bone loss are completely obscured.
