Constant data are represented as number (percentage)
Surgery curative was considered as ‘gold standard’
Chi-square independence test for constant data and One-way repeated-measures ANOVA following Dunnett Multiple comparisons tests for continuous data were used for statistical analysis
A p-value < 0.01 was considered significant
A q-value > 4.148 was considered significant
N/A Not applicable, BL Accurate the Bankart and bony Bankart lesions, I/C Inconclusive results, AUC Area under the curve, Ap Apprehension test, Re Relocation test, Sp Surprise test, Ad Anterior drawer test, LS Load and shift test, Hb Hyperabduction test, TRI The traditional radiological images, CET Clinical Examination Tests, CET + TRI Clinical Examination Tests combining the traditional radiological images, CT The Computed Tomography, SA Statistical analysis
F (+ve): False positive: The Bankart and/or bony Bankart lesions had found in diagnosis, which was led to surgery and actually it was the other bony problem
F (−ve): False negative: A bony problem had found in diagnosis, which was lead arthroscopy or open surgical procedure and actually it was the Bankart and/or bony Bankart lesions
