Abstract. Femoroacetabular impingement syndrome (FAI) is essentially a mechanical conflict that occurs when the acetabulum edge of the pelvic bone interacts with femur head and neck with clinical symptoms. In a basis of this conflict, as a rule, is a single or bilateral anatomical bone defect that causes an irregular shape of the hip joint with congenital or acquired etiology. Radiography, performed in a direct projection and in 45 Dunn position with external rotation of 40, is traditionally considered as basic tool for the radiological diagnosis of hip joint pathology. It allows to assess the anatomical and morphological structure of joint surfaces and their relationship. Detection of severe hip deformations may require computed tomography (CT). Magnetic resonance imaging (MRI) or magnetic resonance arthrography (MRA) is used to assess the condition of soft tissue structures of hip joint, its damage is often found in patients with FAI. The modern method of treating patients with FAI is hip arthroscopy, the undeniable advantage of which is low traumatic nature of the operation, low level of intraoperative complications and short postoperative rehabilitation period. For its successful implementation, it is necessary to take into account the complexity of performing hip arthroscopy, its duration, the necessity for good technical equipment and a high skill level of the operating surgeon. However, this operation has a number of limitations, which must be taken into account when selecting patients.
