Analysis of the distribution of the thickness in the whole capsule using micro-CT. After detaching from the glenoid and humerus, the whole capsule, including the biceps labrum complex, was analyzed based on 3D measurement using micro-CT. a Three landmarks of humeral attachment at the inferior edge of subscapularis insertion (red square), most inferior (red section mark), the margin between infraspinatus and teres minor (red cross) are shown in pictures of the humerus. The inside appearance of the whole capsule, including the long head of biceps brachii (black star), which was flattened is also shown. The whole capsule was divided into 3 approximate parts; anterior (Ant), inferior (Inf), and superior (Sup) according to the site of attachment. Three landmarks correspond to each other. b The distribution of thickness on the whole capsule which is shown in (a) could be identified in the 3D CT image by micro-CT. The color bar represents the approximate thickness (mm) corresponding to the colors. HH, humeral head; SSC, insertion of subscapularis; TMi, insertion of teres minor; ISP, insertion of infraspinatus
