目的：总结23例儿童（平均年龄11．1岁）重度先天性脊柱侧凸采用改良哈氏棒椎弓根螺钉的治疗结果。
Objective:To summarize the result of 23 cases of severe congenital scoliosis children(average 11.1 years) with the modified Harrington rodpedical screw system.
骨移植物和椎间融合器用于前方稳定，同时用椎弓根钉棒系统锁定并植骨作后方稳定。
A bone graft and interbody spacer stabilize the anterior portion while the posterior is locked in place with pedicle screws, rods and bone graft.
术中应用经后路通用脊柱椎弓根钉棒矫形固定系统固定，同时在寰椎后弓和枢椎椎板间大量髂骨植骨融合。
Intraoperative posterior approach general spine pedicle screw-rod orthopaedics fixation system used and iliac bone block were implanted in space of posterior atlantal arch and axial vertebral plate.
结果成功建立正常有效的L3 ~ S1三维有限元模型及椎弓根钉棒系统融合固定三维有限元模型。
Results normal three-dimensional finite element model of normal (L3-S1) and posterior lumbar laminectomy and pedicle screw fixation (models a, b, c) were established successfully.
