概括
在全膝关节整形术 (TKA) 中,增强现实 (AR) 导航有助于骨切除,但不能消除对齐偏差. 外科医生必须确保适当的部件冲击和凝固,以获得最佳的植入物定位.
科学领域:
- 整形外科手术 整形外科手术
- 医疗技术 医疗技术 医学技术
- 生物机械工程 生物机械工程
背景情况:
- 膝关节整形术 (TKA) 的目的是恢复关节功能和对齐.
- 增强现实 (AR) 导航已经引入,以提高TKA的外科精度.
- 评估手术内与术后对齐对于评估TKA结果至关重要.
研究的目的:
- 为了使用AR导航在TKA中比较手术内和手术后的冠状,斜面和轴心对齐.
- 为了确定不完美的植入物定位是否会影响在AR导航的TKA之后的术后对齐.
主要方法:
- 使用AR导航对70个TKA病例的回顾性审查.
- 在手术后的放射图片上评估植入物定位,以确定适当的与不完美的放置.
- 在手术内和术后测量之间对关键对齐参数 (LDFA,MPTA,HKA,PTS,股骨旋转) 的偏差进行分析.
主要成果:
- 在LDFA (61%),MPTA (60%),HKA (60%) 和PTS (67%) 中观察到手术内和术后对齐之间的显著偏差.
- 最重要的偏差发生在膝盖上,植入物位置不完美 (27%),通常是由于足够的股骨部件冲击 (79%) 或骨水泥分布不均 (42%).
结论:
- AR导航在TKA中促进精确的骨切除,但并不能本质上减少对齐偏差.
- 在AR导航的TKA中实现适当的植入物定位需要精细的手术技术,包括适当的部件冲击和均的水泥分布.

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Uncertainty in Measurement: Accuracy and Precision
100.9K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Standard Deviation
27.7K
The most commonly used measure of variation is the standard deviation. It is a numerical value measuring how far data values are from their mean. The standard deviation value is small when the data are concentrated close to the mean, exhibiting slight variation or spread. The standard deviation value is never negative, it is either positive or zero. The standard deviation is larger when the data values are more spread out from the mean, which means the data values are exhibiting more variation.

Mean Absolute Deviation

The mean absolute deviation is also a measure of the variability of data in a sample. It is the absolute value of the average difference between the data values and the mean.
Let us consider a dataset containing the number of unsold cupcakes in five shops: 10, 15, 8, 7, and 10. Initially, calculate the sample mean. Then calculate the deviation, or the difference, between each data value and the mean. Next, the absolute values of these deviations are added and divided by the sample size to...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...
