Cross-sectional imaging of metal-on-metal hip arthroplasties. Can we substitute MARS MRI with CT?

abstract：BACKGROUND:When surgical treatment of dysplastic hip osteoarthrosis is necessary, osteotomy is preferable to fusion or THR. We evaluated periacetabular osteotomy as a method of choice. PATIENTS AND METHODS:We treated 36 symptomatic dysplastic hip joints (32 patients) with the Bernese periacetabular osteotomy (PAO) bet...
