To get information about the importance of malrotation for posttraumatic varus or valgus deformity a clinical, radiological and CT follow-up examination of 20 children who were treated for supracondylar fracture from 1983 to 1985 was done. Rotational-displacement was measured on computed tomographical images taken from the region where fracture had happened. On the ap follow-up X-ray from both, the fractured and the other side, and the X-ray which was made after reduction, the medial and lateral colonne were measured from a "special point" in the middle of the shaft of the humerus. The length of the colonnes and their difference were compared. 15 of the 20 patients showed internal malrotation, 1 patient external malrotation and 4 showed no rotational-displacement. In 15 of the 16 patients with malrotation, the rotational-displacement caused a change in the length of the colonnes. Just in one case malrotation caused a minimal deformity of the carrying angle without alteration of the length of the colonnes. 93% of the cases with internal malrotation showed varus deformity. In 3 cases we saw growth disturbance of the epiphyseal plate, but the induced alteration of the length of the colonnes were minimal compared with the changes caused by malrotation.
为了获取关于旋转不良对创伤后内翻或外翻畸形重要性的信息，我们对1983年至1985年期间接受髁上骨折治疗的20名儿童进行了临床、放射学和CT随访检查。在骨折发生区域的计算机断层扫描图像上测量旋转位移。在骨折侧和对侧的随访前后位X线片以及复位后拍摄的X线片上，从肱骨干中部的一个“特殊点”测量内侧和外侧柱。比较柱的长度及其差异。20例患者中有15例表现为内旋，1例为外旋，4例无旋转位移。在16例有旋转不良的患者中，15例旋转位移导致柱长度改变。仅1例旋转不良导致提携角轻微畸形，而柱长度未改变。93%的内旋病例表现为内翻畸形。3例出现骨骺板生长紊乱，但与旋转不良引起的变化相比，其导致的柱长度改变极小。
