When evaluating dichotomously for presence of a full tear, sensitivity was 82.1% and specificity was 93.9%. Seven (18%) full\u2010thickness tears were missed, and all were essentially small (&lt;15\u2009mm). When physiatrist and radiologist measurements were compared, the mean \u00b1 standard deviation (SD) difference in length was 3.4\u2009\u00b1\u20094.7\u2009mm, width was 2.7\u2009\u00b1\u20096.7\u2009mm, and distance to the biceps tendon was \u22120.8\u2009\u00b1\u20097.5\u2009mm.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Office\u2010based bedside ultrasonography is a reasonable modality to rule out medium\/large full\u2010thickness posterior cuff tears. However, physicians should be aware that a percentage of small full\u2010thickness tears can be missed. Further imaging should be considered in suspected partial tears and full tears that may be appropriate for surgical repair.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pmrj.12256","type":"journal-article","created":{"date-parts":[[2019,10,4]],"date-time":"2019-10-04T00:34:04Z","timestamp":1570149244000},"page":"563-572","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Method
