The computed tomographic (CT) evaluation of patients with orthopedic implants has traditionally been limited due to considerable artifact from the prosthesis. With proper parameter modifications, however, the artifact can be diminished and diagnostic images can be produced. This is a report on the preoperative CT evaluation of a dislocated total hip replacement and dissociated acetabular component.
Two weeks prior to presentation, the patient had a noncemented total hip arthroplasty placed at an outside institution. The patient reported having an uneventful postoperative course, with acute nontraumatic onset of right hip pain.
Standard anteroposterior pelvic and right hip radiographs demonstrated complete dislocation of the right total hip prosthesis with, of note, complete dislodgment of the acetabular component (Fig. 1). Due to extreme pain, the patient was unable to move the leg significantly for a Lauestein lateral radiograph. CT examination was requested.
