One of the most important developments in orthopedic diagnostic radiology in the past 50 years has been that of computed tomography. The cross-sectional display, the capacity to reformat in other planes, the extreme sensitivity to differences in X-ray beam attenuation, the ability to manipulate the contrasts of the images, and the ability to produce blurless tomographic sections of varying thicknesses while the patient, even in a heavy plaster cast, does nothing more than lie still, are some of the capabilities that have enabled computed tomography to improve the way radiology can help the orthopedic surgeon care for patients.

A patient had a spontaneous intracerebellar hemorrhage following coronary artery bypass surgery. His clinical course, characterized by headaches, gait ataxia, and then signs of brain stem compression, is emphasized. Following diagnosis by cranial computerized tomography, successful surgical decompression by suboccipital craniotomy was performed. Reports of neurologic complications, especially intracranial hemorrhage, following coronary artery bypass surgery, are reviewed. Possible pathophysiologic mechanisms for these problems, and the diagnosis and treatment of this previously undescribed complication of coronary artery bypass surgery are discussed.

Rotation of the distal fracture fragment in the supracondylar fracture is a contributing factor in the development of the cubitus varus deformity. Computed tomography (CT) is superior to conventional radiography in the assessment of the position of fracture fragments and was used to study 20 patients with supracondylar fractures after reduction. These fractures were followed up with radiography until healed. As determined from CT scans, rotation of the distal fracture fragment of greater than 10 degrees resulted in an abnormal Baumann angle and a cubitus varus deformity in all patients. Use of CT should facilitate the identification of this complication and thus treatment of these fractures and prevention of subsequent deformity.
