FADIR

Femoroacetabular impingement (FAI) is a common cause of hip pain in young adults. FAI is characterized by impingement of the femoral head-neck junction against the acetabular rim during hip joint movement due to morphological abnormalities of the proximal femur and acetabulum (Griffin et al., 2016; Hale et al., 2021; Schmaranzer et al., 2021; Fortier et al., 2022; Montin et al., 2023).
