概括
在直接前方方法全关节整形术 (DAA THA) 期间进行手术内杯子倾斜测量时,需要进行校正因子,以考虑抛光. 这不管使用的是标准C臂还是平板C臂,都适用.
科学领域:
- 整形外科手术 整形外科手术
- 手术成像技术手术成像技术
- 关节整形 生物力学 机械学
背景情况:
- 直接前方方法 (DAA) 全关节整形术 (THA) 使用手术内光学 (IF) 进行杯子放置.
- 之前的研究已经确定了IF的可靠性,用于测量DAA THA.中的放射杯倾斜度 (RI).
- 之前建议在使用标准的12英寸GE C-arm进行5°校正因子进行抛物线调整.
研究的目的:
- 评估在使用平面板C臂时,是否需要在DAA THA期间使用不同的校正因子进行手术内抛物线调整,而不是在DAA THA期间使用标准C臂.
- 为了将手术内RI测量与不同C臂技术的术后测量进行比较.
主要方法:
- 分析了112名通过DAA与IF接受初级THA治疗的患者队列.
- 放射杯倾斜度 (RI) 在手术期间使用两个C臂模型进行测量:一个12英寸的GE 9900精英和一个OEC精英平面板.
- 在手术期间的测量与手术后的AP骨盆放射图进行了比较.
主要成果:
- 在12英寸GE 9900精英C臂 (n=76) 中,平均手术内RI (35.5°) 比术后测量 (41.9°) 低6.4°.
- 在OEC Elite平面板C臂 (n=36) 中,平均手术内RI (36.1°) 比术后测量 (41.7°) 低5.6°.
- 这两种C臂类型都表现出持续低估了由于抛光而导致的手术内RI.
结论:
- 在DAA THA中进行手术内RI测量时,需要一个校正因子来补偿位.
- 使用的C臂类型 (标准12英寸或平面面板) 不会改变对偏差校正因子的需求.
- 一致的校正因子的应用确保在DAA THA中准确的杯子定位,无论成像设备如何.

Distance Corrections
430
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...

Influence of Earth's Curvature and Atmospheric Refraction on Leveling
1.3K
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

Common Leveling Mistakes and Errors

A survey team is tasked with determining the elevation difference between points Point A and Point B, separated by uneven terrain. They use a leveling instrument and a leveling rod.Common MistakesMisreading the Rod: During a backsight reading at Point A, the instrumentman observes the rod partially obscured by tall grass. Instead of reading 1.135 m, they mistakenly record 1.735 m due to the misalignment of the crosshair with the wrong graduation. This error adds 0.600 m to all subsequent...
