Evaluation of diagnostic imaging modalities for complications after total hip arthroplasty

Abstract

Hip replacement surgery has evolved in line with advancements in implant technology and quality of surgical technique. Radiographs remains first imaging technique used for patient evaluation followed by ultrasonography, computed tomography, magnetic resonance imaging, arthrography, aspiration and nuclear scan techniques. Mechanical loosening, polyethylene wear–induced osteolysis, adverse local tissue reaction due to metal wear debris, infection, fractures, heterotopic ossification, tendinopathy and nerve damage are common causes of painful hip arthroplasty. The radiologist must effectively detect critical concerns with imaging tools while also remaining up to date on additional complications related with advances in surgical technique, implant design, and innovative materials. The present study reviews extensively the clinical and imaging modalities that can be used to better detect complications after hip arthroplasty replacement.
