对于在全关节整形术中对杯子倾斜的手术内测量,需要一个校正因子
概括
在全关节整形手术中,建议在手术期间测量杯子倾斜度时使用4°的校正系数,以考虑位. 对于低位置和的杯子,建议进行特定的调整.
科学领域:
- 整形外科手术 整形外科手术
- 放射性成像成像 放射性成像成像
- 关节整形术是指关节的整形术.
背景情况:
- 在全关节整形术中,准确的杯子倾斜对于尽量减少并发症至关重要.
- 二维射线图投影引入立体效应 (抛物线),改变角度测量.
- 杯子倾斜的光镜测量根据手术方法而异.
研究的目的:
- 为了确定先前引入的纠正因子的可重现性,用于手术内测量杯子倾斜度.
- 评估该校正因子与手术方法和C臂模型的独立性.
主要方法:
- 对377例初级关节整形术病例的综述.
- 在手术内和手术后的放射图像之间比较杯子倾斜角度.
- 基于观察到的差异的标准校正因子的规范.
主要成果:
- 平均手术内杯子倾斜率:37.47°.
- 术后平均杯子倾斜: 41.42°.
- 平均差异为3.95°,测量之间有很强的相关性 (r=0.706).
结论:
- 建议在手术内倾斜度测量时使用4°的校正因子来弥补偏差.
- 对于低位杯子 (<31°) 建议增加6°的校正因子.
- 对于地放置的杯子 (>43°) 建议降低2°的校正因子.

In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...
