Anatomy and Function
The insertions of the supraspinatus and infraspinatus tendons have been further described as a five-layer structure (table 1-2).4 Layer two comprises the main portion of the tendons, though…
Pathogenesis
Figure 1-4. Acromion shape on coronal plane. Schematic drawing of a coronal view of the shoulder. To define lateral acromial angulation, a line is drawn through the mid-substance of the…
Scapulothoracic Joint
Figure 5-38. The two constant bursae at the STJ. Schematic drawing of a superior view of the left shoulder. The supraserratus bursa (ssb) is located between the serratus anterior (sa)…
