概括
在使用piriformis fossa入口门时,埃斯皮诺萨的骨骨折固定技术可能会导致意外的逆转. 外科医生应该考虑使用大三叉体入口门,以避免恶性旋转.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械分析分析
- 骨折治疗方法 骨折治疗方法
背景情况:
- 前级的股骨内髓钉是股骨骨折的常见治疗方法.
- 埃斯皮诺萨技术的目的是利用内指甲的前转来优化股骨旋转.
- 精确的旋转对齐对于骨骨折修复后的最佳功能结果至关重要.
研究的目的:
- 为了比较埃斯皮诺萨技术的可靠性,通过皮里福米斯 (PF) 控制股骨旋转,而不是通过大三角管 (GT) 进入门户.
- 要确定使用埃斯皮诺萨技术时,PF和GT入口门户是否产生类似的旋转对齐.
- 评估入口门选择对导致的股骨前转变的影响.
主要方法:
- 对30个大腿骨的计算机断层扫描 (CT) 扫描进行了回顾性分析.
- 从PF和GT入口点绘制理想的股骨头螺丝轨迹.
- 测量角度以确定相对于距离大腿骨相对于大腿骨前倒的角度.
- 在PF和GT输入钉之间,腿部版本差异的比较.
主要成果:
- 与GT入口点相比,在PF入口点观察到额外回转的平均旋转差异为15.8° ±5.6° (P < 0.001).
- 状的入口门位于更后部和中部,影响旋转对齐.
- 这种差异表明基于所选择的入口门户的旋转控制的显著变化.
结论:
- 使用埃斯皮诺扎技术的piriformis fossa入口门口可以导致平均16°的无计划的术后股骨回转.
- 埃斯皮诺萨技术在实现所需的股骨旋转方面的可靠性取决于门户.
- 为了防止恶性旋转,埃斯皮诺扎技术的使用最好局限于大三叉体入口门口.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...
