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.
髁上骨折中远端骨折块的旋转是肘内翻畸形发展的一个促成因素。在评估骨折块位置方面，计算机断层扫描（CT）优于传统放射摄影，并被用于研究20例复位后的髁上骨折患者。这些骨折通过放射摄影进行随访直至愈合。根据CT扫描结果，所有患者中远端骨折块旋转超过10度会导致鲍曼角异常和肘内翻畸形。使用CT应有助于识别这种并发症，从而对这些骨折进行治疗并预防后续畸形。
