It attaches medially to the dorsal surface of the scapula just below the infraspinatus and inserts laterally into the greater tubercle of the humerus. (See Figure 6-23A .) It is innervated by the axillary nerve through the posterior cord from C5 and C6 spinal nerves.In the infraspinatus muscle, ... The treatment of muscle atrophy and fat accumulation using the GnP matrix exhibited a positive effect on tendon-to-bone insertion maturity compared with NR-32 and S-32.
