Les clichés simples du bassin

Plain films of pelvis Plain films of the pelvis remain informative and allow most of the diagnoses. Assesment of the hip joint space, bone and subchondral structures, sacrum as well as sacroiliac joints is made on the AP view. Oblique views are useful. Five different oblique views are described: Lequesne’s view, Ducroquet’s view, Arcelin’s view, medical and urethral views. They particularly allow assement of the acetabulum, the femoral head and neck as well as the femoral superior third. Radiological technique and major indications for these views must be known. Angle measurement and evaluation of possible dysplasia are made on coxometry views.
