title: [Imaging of complications following hip arthroplasty].
abstract: Acute complications include fractures and prosthesis dislocations. Most chronic complications involve mechanical or septic loosening and aggressive granulomatosis. Greater trochanteric pseudarthrosis, periprosthetic soft tissue ossifications or prosthesis conflict with the psoas muscle can also be responsible for groin pain. Most complications are detected with serial plain radiographs, but additional imaging techniques including CT scan and scintigraphy are sometimes necessary for pretreatment diagnosis. Pain generally indicates a complication but aggressive granulomatosis can be asymptomatic, thus warranting systematic annual plain radiographic control.
