目的： 本研究旨在评估三维CT测量肩盂轨迹的可靠性和可重复性。
方法： 由3位独立观察者（肩关节专科医生）通过三维CT评估60例单侧肩关节复发前脱位患者的肩胛盂及Hill-Sachs骨缺损情况，并按Di Giacomo等的方法，将损伤分类，制定手术方案。所有观察者在1周后重复测量。采用组内相关系数（intraclass correlation coefficient，ICC）及变异系数（coefficient of variation，COV）进行可靠性分析。
结果： 在肩胛盂直径及肩胛盂骨缺损的测量中，观察者间的可靠性均为"非常好"，对Hill-Sachs间隙的测量，观察者间的可靠性为"好"；在肩胛盂缺损程度的评估上观察者间的一致性很高，在Hill-Sachs损伤on-track/off-track的评估上观察者间的一致性较差。肩胛盂直径、肩胛盂骨缺损、Hill-Sachs间隙测量观察者内的可靠性均为"非常好"。肩胛盂直径、肩胛盂骨缺损的COV分别为4.1%和4.4%，Hill-Sachs间隙的COV为21.1%。
结论： 三维CT测量肩胛盂骨缺损的可靠性、可重复性高，但对肱骨头骨缺损的评估显示出较大的可变性，可靠性较差。 |

| Reliability of three-dimensional CT measurement of glenoid track in patients with recurrent anterior dislocation of shoulder |
|
Abstract:
Objective: To evaluate the reliability and repeatability of three-dimensional (3D)-CT measurement of glenoid track.
Methods: Glenoid and Hill-Sachs bone defects in 60 patients with recurrent anterior dislocation of the unilateral shoulder were evaluated by 3D-CT and analyzed by three independent observers(shoulder orthopedists) according to the Di Giacomo method. These injuries were classified to formulate a surgical protocol. All the patients were repeatedly measured 1 week later. Intraclass correlation coefficient (ICC) and coefficient of variation (COV) were used for reliability analysis.
Results: Interobserver reliability was "very good" for both measurements of glenoid diameter and glenoid bone defects,and "good" for measurements of Hill-Sachs interval. Interobserver agreement was high on the assessment of the extent of the glenoid defect, and poor on track/off track assessment of the Hill-Sachs lesion. Intraobserver reliability for measurements of glenoid diameter,glenoid defect,and Hill-Sachs interval was "very good". The COV was 4.1% for glenoid diameter,4.4% for glenoid defect,and 21.1% for Hill-Sachs interval.
Conclusion: The reliability and reproducibility of 3D-CT measurements of glenoid bone defects are good,but the assessment of humeral head bone defects shows large variability with poor reliability. |
