三维重建CT在儿童胫骨远端三平面骨折诊断与治疗中的应用

The application of three-dimensional reconstruction of CT on the diagnosis and treatment of the adolescence distal tibial triplane fracture

目的探讨三维重建C T对儿童胫骨远端三平面骨折诊断及治疗的作用。方法对2003年4月～2009年10月收治的121例胫骨远端骨骺损伤的X线片、普通C T及三维重建C T进行回顾性分析。结果诊断三平面骨折22例。其中,2006年以前12例,未行三维重建C T检查,病人均诊断为Ⅲ型、Ⅳ型骨骺损伤。2006年以后通过三维重建C T确诊三平面骨折10例,并根据骨折块移位情况选择切口进行手术内固定治疗。结论三维重建C T对胫骨远端三平面骨折的诊断阳性率为100%,对该类骨折治疗方案及手术切口的选择具有重要的参考价值。

【Objective】 To approach the application of three-dimensional reconstruction of CT on the diagnosis and treatment of the adolescence distal tibial triplane fracture.【Method】 Retrospective study of effect of X-ray,CT and three-dimensional reconstruction of CT on 121 patients suffered epiphyseal injury from April 2003 to October 2009 was carried out.【Results】 22 cases of the adolescence distal tibial triplane fracture（12 cases didn＇t undergo three-dimensional reconstruction of CT before 2006） were III or IV epiphyseal injury.10 cases which underwent three-dimensional reconstruction of CT were treated by open reduction internal fixation in accordance with the condition of bone fracture.【Conclusion】 The diagnosis rate is 100% to diagnose the adolescence distal tibial triplane fracture with three-dimensional reconstruction of CT,and it is an important examination method for how to select the way of operation and treatment.
