Computed tomography of joint injuries.

CT has become the imaging modality of choice in most acute and chronic injuries involving the articular surfaces. Today's technology allows high resolution, fast scanning, and rapid reformatting, all of which contribute to prompt orthopedic evaluation and decision making. Our orthopedic colleagues have come to rely on high-quality CT scans in order to evaluate calcaneal and tibial plateau fractures, stress fractures, osteochondritis dissecans, acute and chronic shoulder trauma, and problems of the painful wrist--especially the distal radioulnar joint.
