In a standard anteroposterior view, the radius of the best\u2010fit circle of humeral head and the radius of the concentric circle passing through the most lateral edge of the greater tuberosity were measured in each shoulder. The ratio of these two radiuses was named as the double\u2010circle radius ratio. Angular parameters including the greater tuberosity angle and the critical shoulder angle were also measured in the anteroposterior view. Independent samples <jats:italic>t<\/jats:italic> tests and chi\u2010square tests were used to find significant differences between groups. Significant associations between those measured variables and demographic characteristics were analyzed with simple linear regression analysis. Receiver operating characteristic curves were pictured to determine applied cutoff values by using Youden index. Multivariable\u2010adjusted analysis for the occurrence of rotator cuff tears was carried out by using multiple logistic regression analysis. For all tests a <jats:italic>p<\/jats:italic> value of &lt;0.05 was considered statistically significant.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred and twelve shoulders with rotator cuff tears and 42 shoulders without rotator cuff tears were included. The mean value of the double\u2010circle radius ratio was significantly larger in shoulders with rotator cuff tears (1.42\u2009\u00b1\u20090.09 vs. 1.30\u2009\u00b1\u20090.07, <jats:italic>P<\/jats:italic>\u00a0=\u00a00.000). With simple linear regression analysis, the radiuses of the humeral head and the greater tuberosity were significantly associated with heights and weights. In receiver operating characteristic curves, the largest area was found under the curve of the double\u2010circle radius ratio as 0.846 (95% CI, 0.781\u20130.911; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.000) with an applied cutoff value as 1.38 (sensitivity, 70.5%; specificity, 88.1%). Multivariable\u2010adjusted analysis showed that a value of the double\u2010circle radius ratio\u2009&gt;1.38 resulted in 11.252\u2010fold odds of developing rotator cuff tears (95% CI,
