title: Supracondylar fractures of the humerus: prediction of the cubitus varus deformity with CT.
abstract: 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.
