FIGURE 111.35 Radiographs taken following closed reduction of a right hip dislocation A: The plain film demonstrates residual widening of the joint space (arrows ) B: Widening is also apparent with magnetic resonance imaging, as is entrapment of a portion of the posterior joint capsule (arrow ) Under general anesthesia, further efforts at closed reduction were successful Treatment of hip dislocation is closed reduction This will usually be done by an orthopedist under procedural sedation in the ED or in the operating room under general anesthesia In adolescents, reduction under anesthesia is recommended as occult epiphyseal injury may be present in this age group with hip dislocation, and epiphyseal separation may occur during reduction However, given the importance of a timely reduction, in select cases, hip reduction may be performed by emergency clinicians For a posterior hip dislocation reduction, the hip and knee should be flexed to 90 degrees and with the pelvis stabilized,
