计算机断层扫描 (CT) 检测到远距离半径骨折 (DRF) 的不整齐性比造后的普通X射线扫描更多. 在53%的病例中,CT检测出错位,往往需要手术.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 创伤护理的护理人员.
背景情况:
- 距离半径骨折 (DRFs) 是常见的伤害.
- 评估骨折调整后减轻对最佳结果至关重要.
- 平面放射是标准的成像方式,但其在检测微妙的错位的准确性是有争议的.
研究的目的:
- 为了比较计算机断层扫描 (CT) 与普通X射线扫描的诊断准确性,在闭合缩减和件固定后评估远距离半径骨折 (DRF) 的不对齐.
- 为了确定CT扫描是否显示在标准放射图上不明显的不对齐.
主要方法:
- 对96名DRF患者进行了回顾性审查,这些患者接受了封闭的减少和造治疗.
- 使用荷兰指南标准 (角化,倾斜,肘部变异,关节内脱节/间隙) 评估了放射性对齐.
- 进行了减少后的CT扫描并与初始放射图进行比较,以确定对齐评估中的差异.
主要成果:
- 在所有测量参数的放射和CT评估之间观察到显著差异.
- CT扫描经常发现关节内脱节和间隙变化,导致从"对齐"重新分类到"不对齐".
- 在53%的病例中,CT显示出不对齐,其中73%需要手术干预.
结论:
- 计算机断层扫描 (CT) 在闭合缩减和造后检测远半径骨折 (DRFs) 的不对齐性方面比普通放射学更为敏感.
- 关节内不一致性通常通过CT更好地可视化,影响治疗决策.
- 推CT扫描,当放射性评估提出怀疑后减少骨折对齐.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
