1、3种摄片方法预测青少年特发性脊柱侧凸矫形结果的对比研究【摘要】10/10评估术前站立位、支点弯曲位、重力悬吊牵引位和仰卧侧屈位X线片在预测青少年特发性脊柱侧凸三维矫形融合术效果的价值。［方法］对63例青少年特发性脊柱侧凸患者的79个结构性侧凸摄术前站立位、支点弯曲位、重力悬吊牵引位和仰卧侧屈位X线片，将其与术后的站立位X线片比较，测量全部Cobbs角后进行统计学处理，并评估其价值。［结果］结构性胸凸组与结构性腰凸组重力悬吊牵引位片Cobbs角分别是40°和21°，仰卧侧屈位片Cobbs角分别是41°和23°，支点

2、弯曲位片Cobbs角分别是35°和19°，术后站立位片Cobbs角分别是36°和18°；重度组（≥60°）与中度组（＜60°）重力悬吊牵引位片Cobbs角分别是52°和23°，仰卧侧屈位片Cobbs角分别是53°和24°，支点弯曲位片Cobbs角分别是47°和20°，术后站立位片Cobbs角分别是44°和19°；僵硬组与柔软组重力悬吊牵引位片Cobbs角分别是51°和22°，仰卧侧屈位片Cobbs角分别是52°和22°，支点弯曲位片Cobbs角分别是48°和18°，术后站立位片Cobbs角分别是45

3、°和17°；前路手术组与后路手术组重力悬吊牵引位片Cobbs角分别是47°和15°，仰卧侧屈位片Cobbs角分别是49°和16°，支点弯曲位片Cobbs角分别是43°和11°，术后站立位片Cobbs角分别是42°和10°，以上角度均为平均值。平均随访时间是年（11~37个月）。［结论］支点弯曲位X线片比重力悬吊牵引位和仰卧侧屈位X线片能更准确地预测术后矫正效果，并能为选择前路或后路术式，以及融合节段提供依据。【关键词】青少年特发性脊柱侧凸影像学柔韧性脊柱融合Comparativeanalysisofthreer
