The purpose of the study is to evaluate the updated version of this software in patients with various spinal deformity.
Sixty patients were included in this study and were divided into three categories: 20 patients with AIS, 20 patients with ASD, and 20 patients having undergone corrective surgery for spinal deformity. The measurements were performed by two senior and two junior orthopedic surgery residents, and were done at two points in time separated by a 3-week interval with the cases being randomized every time to reduce the risk of memory bias. Measured parameters included coronal, sagittal, global alignment parameters, and pelvic parameters.
When assessing the inter- and intra-observer reliability across all the groups of patients, none of the coefficients was smaller than 0.8 with a very high level of agreement. The standard error ranged from 0.7° to 1.5° demonstrating a high level of accuracy. Fairly similar results were seen when the groups were divided into the three categories except for the post-operative groups where a strong and not perfect level of agreement was reported.
This is the first study to assess the reproducibility of the new version of KEOPS, showing a very high agreement in all measurements. In the post-operative group, although it showed a strong agreement, the lower performance can be explained by the presence of surgical material making it harder to identify the anatomical landmarks accurately. Nevertheless, we can recommend the usage of this software in a clinical setting.
本研究旨在评估该软件的更新版本在各种脊柱畸形患者中的应用。
本研究纳入 60 例患者，分为 AIS 组（20 例）、ASD 组（20 例）和脊柱畸形矫正手术组（20 例）。由 2 名资深和 2 名初级骨科住院医师进行测量，两次测量时间间隔 3 周，每次病例随机分组，以降低记忆偏差的风险。测量参数包括冠状位、矢状位、整体对齐参数和骨盆参数。
在评估所有患者组的组内和组间可靠性时，所有系数均大于 0.8，具有非常高的一致性。标准误差范围为 0.7°至 1.5°，表明具有很高的准确性。当将组分为三类时，除术后组外，结果非常相似，术后组报告的一致性为强但不完美。
这是第一项评估 KEOPS 新版本可重复性的研究，所有测量均显示出非常高的一致性。在术后组中，尽管它显示出很强的一致性，但较低的性能可以解释为存在手术材料，使得更难准确识别解剖标志。然而，我们可以推荐在临床环境中使用该软件。
