概括

脊椎骨盆角 (VPA) 证明了在成年脊柱形中评估脊柱对齐的卓越可靠性. 然而,最小可检测变化 (MDC) 很高,这意味着可能会错过显著的对齐转移.

科学领域:

整形外科整形外科整形外科
放射学放射学是一门学科.
脊柱外科手术脊柱外科手术

背景情况:

脊椎骨盆角 (VPA) 越来越多地用于评估脊柱形状.
在临床实践中,可靠性和最小可检测变化 (MDC) 对于解释VPA测量至关重要.

研究的目的:

评估VPA测量的观察者内部和观察者间的可靠性.
确定成人脊椎形 (ASD) 中VPA的MDC.

主要方法:

三位独立检查员对成年脊柱形患者进行了重复的VPA测量.
计算了类内相关系数 (ICC) 和MDC.
排除标准包括先前的部/肩膀手术和放射性限制.

主要成果:

内部观察者ICC值在0.90到0.99之间,表明其可靠性很高.
观察者间ICC值非常出色,范围从0.92到97.97.
MDC值在4.1°至5.3°之间,被认为相对较高.

结论:

VPA在评估脊柱对齐方面表现出卓越的观察者内部和观察者间可靠性.
相对较高的MDC表明,与单个VPA测量可能无法检测到实质性的对齐变化.
外科医生在解释ASD患者的VPA变化时应考虑MDC.

Adjusting a Traverse

Adjusting a Traverse

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...
