Description
- Surface of Humeral Head
- Greater Tuberosity (where it begins a footprint)
- The Most Distal Greater Tuberosity (facet profiles)
Description
- 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.
