We aimed to determine whether the distance between the midpoints of the supraspinatus central tendon and long head of the biceps tendon on a sagittal shoulder magnetic resonance imaging scan can help to preoperatively diagnose an injury of the anterior insertion of the supraspinatus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>This retrospective study reviewed 103 patients with a full\u2010thickness supraspinatus tendon tear: 50 patients with (injured group) and 53 patients without (intact group) anterior supraspinatus insertion tear. The inter\u2010tendon distance was measured based on an oblique sagittal magnetic resonance imaging scan. SPSS was used for statistical analyses.

The inter\u2010tendon distance of the injured group was significantly greater than that of the intact group (10.1\u2009\u00b1\u20092.7 vs 8.0\u2009\u00b1\u20092.3\u2009mm, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The diagnostic ability of the inter\u2010tendon distance was fair (area under the curve\u2009=\u20090.745), and a threshold of 9\u2009mm had a specificity of 73% and sensitivity of 74%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The distance between the supraspinatus central tendon and long head of the biceps tendon on magnetic resonance imaging was greater in patients with anterior supraspinatus insertion injury than those without the injury.
