FIELD: traumatology; orthopedics.SUBSTANCE: used for arthroscopy of the hip joint to eliminate Cam or combined types of femoroacetabular impingement. A proximal anterolateral port is created to the peripheral portion of the hip joint, which is used as a viewing port at the beginning of the operation; 4 cm distal and 2 cm lateral to the intersection of the midline of the femur and the perpendicular drawn to it through the apex of the greater trochanter, an anterior port is created, which is used as an instrumental port at the beginning of the operation. The deformation zone is brought to the bone burr, changing the positions of flexion and extension, internal and external rotation of the lower limb, and until the appearance of spring resistance of the fibers of the lateral joint capsule and the ileofemoral ligament, resection of excess bone mass of the anterior surface of the proximal femur within the boundaries of the Cam-deformation is performed. The viewing and instrument ports are changed and the deep fibers of the proximal joint capsule and the ileofemoral ligament are released from the acetabulum. In the presence of Pincer deformity, soft tissues are removed to visualize excess bone mass within the boundaries of the Pincer deformity, and resection of excess bone mass of the anterolateral edge of the acetabulum within the boundaries of the Pincer deformity is performed until radiographic visualization of the absence of intersection of the anterior and posterior edges of the acetabulum. The viewing and instrument ports are replaced. An arthroscope is positioned on the outer edge of the joint capsule fibers, and bone resection of the posterolateral surface of the proximal femur is completed within the boundaries of the Cam deformity by inserting a bone burr from the skin incision of the anterior port into the capsule opening of the proximal anterolateral port, preserving the fibers of the joint capsule and the ileofemoral ligament.EFFECT: method ensures correction of the proximal femur within the boundaries of the Cam-deformation while maintaining the integrity of the structures of the passive capsular-ligamentous stabilizers and eliminates the development of complications in the form of microinstability of the hip joint, anterior dislocation of the femoral head, heterotopic ossification due to maintaining the integrity of the structures of the passive capsular-ligamentous stabilizers and eliminating the development of microinstability of the hip joint, anterior dislocation of the femoral head and heterotopic ossification.1 cl, 1 ex
