title: Imaging of the acetabular labrum.
abstract: The acetabular labrum is a critical structure within the hip joint. It is a significant cause of pain, and it plays an integral role in the development of osteoarthritis. This article reviews the normal anatomy, imaging techniques, and normal MR appearance of the labrum. The clinical presentation of labral tears and their association with developmental dysplasia and femoroacetabular impingement are discussed. The controversy regarding the presence or absence of a sublabral sulcus also is addressed.
