BACKGROUND: Femoroacetabular impingement (FAI) is a common cause of hip pain in young adults. We retrospectively characterized demographic and diagnostic features of femoroacetabular impingement (FAI) on standard magnetic resonance imaging (MRI) and MR arthrography (MRA).
METHODS: We retrospectively analyzed 482 hip MRI examinations (462 standard MRI, 20 MRA) of patients aged 20-50 years, referred to our department with chronic hip pain. Two investigators evaluated MR images to assess demographic data and diagnostic features of FAI.
RESULTS: FAI resulted the second most frequent hip pathology, with a frequency of 23.64% and a prevalence of 8.3% (25 males, 14 females; mean age 38.1 years). Cam FAI (frequency 32.25%) resulted the most frequent type in the FAI group, with a higher prevalence in males. Combined-type FAI resulted to be the group with the lowest average age. Alpha angle resulted higher in the cam-type FAI; acetabular depth was greater in combined-type FAI. Cam group was characterized by greater alpha angle, osseous bump at the femoral neck, and acetabular anterosuperior cartilage abnormalities. In pincer-type FAI, the most significant finding was a cystic area at the femoral neck. MRA resulted to be superior to MRI for diagnosing acetabular labral abnormalities and acetabular chondropathy; there was no significant difference between MRA and MRI in assessing femoral head chondropathy.
CONCLUSIONS: FAI is a common cause of chronic hip pain in young adults. MRA is confirmed the gold standard for evaluating labral abnormalities. Nevertheless, it is essential to recognize all morphological hip alterations on MRI in the complex scenario of chronic hip pain.
