Where does infraspinatus insert
The infraspinatus inserts on approximately half of the superior facet and the entire middle facet of the greater tuberosity. The insertion area of the supraspinatus is located at the anteromedial part of the superior facet and is sometimes located at the most superior part of the lesser tuberosity (Figure 10, additional material) [ 17 ].Supraspinatus and Infraspinatus. The Supraspinatus is a relatively small muscle of the upper back that make up the rotator cuff. The supraspinatus and infraspinatus muscles starts from 2 large fossae, 1 above and 1 below the spine, on the posterior surface of the scapula. They create tendons that insert on the greater tubercle of the humerus.Infraspinatus originates from the infraspinous fossa of the scapula, located on the dorsal aspect of the scapula below the scapular spine. It inserts on the middle facet of the greater tuberosity. Its primary …
