Occult acute fractures. Greater tuberosity fracture. a Coronal oblique US obtained over the supraspinatus tendon (SSt). b A-P standard radiograph and c, d 2D (c) and 3D (d) reconstructed CT of the shoulder. In a, US shows a non-displaced fracture of the greater tuberosity (GT) of the humeral head (HH). Associated thickening of the wall of the subacromial bursa is present (white arrowhead). Standard radiographs were interpreted as normal. A second lecture made after US showed a possible “in situ” fracture (arrow). CT confirmed the US findings
