摘要
目的 探讨TRAFIX内固定系统在脊柱侧凸矫正中的应用方法 ,以提高脊柱侧凸矫正手术疗效。 方法 自 1997年 10月始应用TRAFIX内固定系统对 2 7例特发性脊柱侧凸患者实施矫正手术 ,其中女性 2 0例 ,男性 7例 ;平均年龄 14岁 (11～ 2 1岁 )。接受前路松解手术 4例 ,第 2次矫正手术 1例。平均随诊时间 2 6个月 (13～ 37个月 )。 结果 术前侧凸平均冠状面畸形为 6 5°(4 2°～110°) ,术后矫正至 2 9°(3°～ 6 4°) ,平均矫正率为 5 5 4% ,平均融合节段为 11 5个 (7～ 17个 )椎体。主侧凸顶椎与第 7颈椎 (C7)垂线距离手术前后分别为 5 2 1mm(2 5～ 94mm)和 2 8 5mm(4～ 6 2mm)。 结论 TRAFIX内固定系统对脊柱侧凸在三维平面同时产生矫正 ,特别表现为内置物精巧 ,操作方便 。
Objective To evaluate the results of TRAFIX internal fixation system in correction of adolescent scoliosis. Methods From October 1997 to June 1999, 27 patients with idiopathic scoliosis received spinal instrumentation with TRAFIX system. Their average age was 14 2 years (from 11 to 21). Four patients of the 27 underwent anterior relaese, while 1 patient accepted revision approach. The average follow up time was 26 months (13 37 months). Results The measurements for primary coronal deformity before and after surgery were 65°(42° 110°) and 29 2°(3° 64°) respectively. The average curve correction was 55 4%. The average fused segments were 11.5 vertebrae. The distance between the center of apex and C7 plumb line was 52 1 mm before operation (25 94 mm) and 28 5 mm after surgery (4 62 mm). Conclusion The TRAFIX internal fixation system provides three dimensional correction with refinement, convenient and reliable fixation.
