Assessing osteonecrosis of the femoral head after internal fixation of femoral neck fractures : MARS MRI versus conventional radiography and patient-reported outcomes
Background and purpose — Little is known on the use of metal artifact reduction sequence (MARS) MRI to diagnose osteonecrosis of the femoral head (ONFH) after fixation of femoral neck fractures (FNF) with conventional metal implants present. We compared MARS MRI with radiography in diagnosing ONFH. Secondarily, we determined whether signs of ONFH on MARS MRI correlate with patient-reported outcome
