Latissimus Dorsi. OVERVIEW. Key Points: • Latissimus dorsi abducts, extends and internally rotates the shoulder. • Important muscle to examine because its function is often maintained in even very severe brachial plexus injuries where it can act as a donor nerve for nerve transfer procedures. EXAMINATION.

The scapula is a flat, triangular-shaped bone (colloquially as the "shoulder blade"). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint. In total, 17 different muscles attach to the scapula, which makes it difficult to fracture.
