【摘要】 [目的]探索一种内固定材料塑形新方法。[方法]扫描并三维重建健侧胫骨,在健侧测量患侧拟行L形钢板固定的横、纵曲线形状及各长度参数,然后利用曲线描绘工具等比例绘出2曲线。最后以2曲线为基础对L形钢板塑形。[结果]准确测量出了2曲线的形状及各长度参数,并等比例绘出了健侧2曲线,最后成功对钢板进行了塑形。[结论]该方法完全能等比例绘出拟行内固定的曲线,并对钢板进行塑形,可显著提高内固定物与胫骨表面的贴附率,缩短手术时间,提高手术疗效。部分病例健侧骨质增生可能影响塑形精度,但通过健侧仍可将内置板材塑出基本形状,术中稍微修改即可。更多还原

【Abstract】 [Objective]To explore a new technique of prefabricating internal plate.[Method]Three-dimensional reconstruction of the well-liking shinbone was performed by MSCT scanning and the length and shape of the catagmatic shinbone for operation was measured on well-liking shinbone.The shinbone curve was depicted using a self-designed skeletal curve-depicting.Then shape of the material for internal fixation was determined.[Result]The length and shape of the shinbone curve was accurately measured.The physiological curve of the shinbone was depicted.Then shape of the material for internal fixation was determined.[Conclusion]Three-dimensional well-liking shinbone reconstruction with MSCT and measurement facilitates the determination of the optimal length and shape of the internal fixation material to enhance the attachment between the material and the bone surface and consequently the therapeutic effects.One case’s length and shape of internal fixation was dissatisfactory for hyperplasia of bone.But the length and shape of internal fixation has basal shape.更多还原
