摘要
背景:拇外翻的影像学评估是一个必要的过程。残留的旋转畸形与较高的复发率相关。本研究旨在全面评估从平片和负重CT扫描中测量各种参数的可靠性。方法:对40张术前x线平片、40张术后x线平片及37张负重CT片进行评估，确定外翻参数的可靠性。结果:与其他用于横切面评估的参数相比，TSP和头形代表冠状面畸形在观察者间的可靠性较低，尤其是在术后。(3个评估者的术后TSP: κ = 0.386, 0.520, 0.340;在负重CT扫描中，用α角度评价第一跖骨旋转在观察者间(ICC = 0.853 (95% CI = 0.715-0.925))和观察者内(ICC = 0.902 (95% CI = 0.844-0.939))均显示出非常好的可靠性。结论:负重CT扫描可提高术后冠状面评估的可靠性。
Reliability improvement in Hallux Valgus measurement using weight-Bearing CT scan.
Background: Radiographic assessment of hallux valgus is an essential process. Residual rotational deformity was shown associated with higher recurrent rate. This study aims to comprehensively assess reliability of measurement of various parameters from plain films and weight-bearing CT scan. Methods: A total of 40 pre-operative plain radiographs, 40 post-operative plain radiographs, and 37 weight-bearing CT scan were evaluated to determine reliability of hallux valgus parameters. Results: TSP and head shape representing coronal plane deformity showed lower inter-observer reliability compared to other parameters using for transverse plane evaluation especially in post-operative period. (post-op TSP amongst 3 assessors: κ = 0.386, 0.520, 0.340; post-op head shape: κ = 0.374, 0.375, 0.295) Using α angle for evaluation 1st metatarsal rotation in weight-bearing CT scan demonstrated very good reliability for inter-observer (ICC = 0.853 (95% CI = 0.715-0.925)) and intra-observer (ICC = 0.902 (95% CI = 0.844-0.939)). Conclusion: Weight-bearing CT scan can improve reliability in post-operative coronal plane assessment.
