[Effectiveness analysis of Lenke type 1 adolescent idiopathic scoliosis with different proximal fixation vertebra].

To investigate the short-term effectiveness of proximal fixation of one vertebra above to the upper end vertebra and the upper end vertebra in the treatment of Lenke type 1 adolescent idiopathic scoliosis (AIS) patients with preoperative right higher shoulder. The clinical data of 37 Lenke type 1 AIS patients treated with posterior correction between January 2010 and December 2015 were retrospectively analysed. According to proximal fixation vertebra, the patients were divided into 2 groups: group A ( The operation time and intraoperation blood loss in group A were significantly greater than those in group B ( For Lenke type 1 AIS patients with preoperative right high shoulder, proximal fixation vertebra be fixed to the upper end vertebral can obtain satisfactory short-term orthopedic effectiveness and reduce blood loss and operation time. 探讨近端固定在上端椎上一椎体与上端椎治疗术前右肩高的 Lenke 1 型青少年特发性脊柱侧弯（adolescent idiopathic scoliosis，AIS）的近期临床疗效。. 回顾分析 2010 年 1 月—2015 年 12 月行后路矫形手术治疗的 37 例 Lenke 1 型 AIS 患者临床资料，按照近端固定椎不同分为两组：A 组（17 例），近端固定至上端椎上一椎体；B 组（20 例），近端固定至上端椎。两组患者性别、年龄、Risser 征、双肩影像学高度差（radiographic shoulder height，RSH）、上胸弯柔韧度、主胸弯柔韧度、胸腰弯/腰弯柔韧度等一般资料比较差异无统计学意义（ A 组手术时间和术中出血量均显著大于 B 组（ 对于术前右肩高的 Lenke 1 型 AIS 患者，近端固定椎选择上端椎即可获得满意的近期矫形效果，还可减少术中出血量和手术时间。.
