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.
