Reliability of FABER test in correlation with alpha angle in diagnosis of cam type femoroacetabular impingement

Femoroacetabular impingement is a condition characterised by an abnormal contact in between the head of femur and the acetabulum which leads to labral damage and various degrees of chondral injury. The Flexion Abduction External Rotation (FABER) test is a broad provocation test done to detect hip, lumbar or sacroiliac joint pathology. The aim of this study is to assess the reliability of FABER test in diagnosis of cam type femoroacetabular impingement by comparing it with radiological findings. In this prospective study it was concluded that the FABER test is sensitive and has a significant positive predictive value for the diagnosis of cam type femoroacetabular impingement where as a negative FABER test cannot completely rule out this diagnosis as it has a relatively low specificity
