Coracobrachialis and biceps short head origin is a conjoint tendon

Tendon Insertion: not tendinosis This is a normal tendon showing the expected anisotropic insertion.

Greater Tuberosity Middle Facet Footprint of Infraspinatus/Supraspinatus

Anterior Facet (Supraspinatus Insertion) Middle Facet (Interdigitated Supraspinatus-Infraspinatus Insertion)—this combined insertion stretches from the anterior part of the greater tuberosity, where most of the fibers are from the supraspinatus, to the posterior part of the middle facet where most of the fibers are from the infraspinatus. In the center of this attachment complex fibers from supraspinatus and from infraspinatus interdigitate, and the tendons cannot be distinguished.
