Assessing osteonecrosis of the femoral head after internal fixation of femoral neck fractures in young patients with fixation implants in situ: the value of MARS MRI in relation to conventional radiography and patient-reported outcomes
Abstract: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 outcomes (PROs) via Oxford Hip Score (OHS) and pain (VAS).Patients and methods: 30 adults under 60 years treated with inter… Show more
