防治肘内翻畸形,是儿童肱骨髁上骨折治疗过程中的重要课题。作者运用肌力平衡,力线复位,肘伸直旋后位固定方法治疗,效果满意, 治愈率达100％。机理是:肘部力线复位后肘伸直旋后位固定治疗可以削弱旋后肌的力量,平衡肘部肌力,防止折端旋转移位。旋后位固定后地心引力由尺侧方向改变为前臂的背侧方向,通过内外侧韧带的肌力平衡作用,在力线复位的情况下可以纠正尺嵌及缺损,从而防止肘内翻畸形。本法淡化对位,强调纠正上肢力线,重视治疗结果。
Prevention and treatment of cubitus varus deformity is an important issue in the treatment of supracondylar humerus fractures in children. The authors use the balance of muscle strength, force line reduction, elbow extension posterior fixation method, the effect is satisfactory, the cure rate of 100%. The mechanism is: elbow force line reset elbow extension posterior fixed therapy can weaken the power of the supination muscle, balance elbow muscle strength, to prevent the rotation of the folding end of the shift. Gyro-posterior position fixed gravity change from the ulnar direction to the dorsal direction of the forearm, through the lateral and lateral ligament muscle strength balance in the case of force line reset ruler and defect can be corrected to prevent cubitus varus deformity . This Law desalination alignment, emphasizing the correction of upper limb force line, attention to treatment results.
