dc.description.abstractIntroduction: It was aimed to compare the patients having clinical and radiological diagnosis of femoroacetabular impingement syndrome with the control group by magnetic resonance imaging, and alpha angle and the central corner angle described by Wiberg. Material and Method: Routine hip MRIs were analyzed retrospectively between January 2016 and May 2019. Clinically and radiologically, patients diagnosed with cam, pincer, and mixed FAI were recorded. A control group matching age and sex was created. The alpha angle was determined as the angle between the line drawn from the center of the femoral neck to the center of the femoral head in axial T1A magnetic resonance imaging, and the line drawn from the center of the femoral head to the point where the femoral head begins to turn towards the neck.Central corner angle of Wiberg’s was measured as the angle between the perpendicular line drawn from the center of the femoral head to the acetabulum on the coronal T1A images and the line connecting the outermost point of the acetabulum. Measurements were compared statistically in both groups. p<0.05 was considered statistically significant. Results: 16 of 28 patients (18 men, 10 women) with FAI had impingement in both hips and a total of 44 hips were examined. There were 9 cam, 23 pincer and 12 mixed impingement cases in the patient group. When FAI and control groups were compared, alpha and Wiberg’s angles were found to be significantly different (p<0.05). In subgroup analysis, there was a significant difference between cam type and control group, mixed type and control group, pincer type and cam type, pincer type and mixed type in terms of alpha angles (p<0.05). For Wiberg’s angles, a significant difference was found between pincer type and control group, mixed type and control group, pincer type and cam type, mixed type and cam type (p<0.05). Cut off values were 54.45 (auc=0.64) for alpha angle and 37.30 (auc=0.83) for Wiberg angle. Conclusion: Alpha angle measurement cam type and Wiberg angle measurement provide useful information for the diagnosis of pincer type impingement with MRI.
