7. Algorithm for the study of the brachial plexus
Evaluation of the spinal nerves - C5, C6, C7 at the level of the transverse processes of the vertebrae, the upper and middle trunks of the brachial plexus at the level of the interstellar space. Suprascapular nerve - visualization. Assessment of the brachial plexus at the level of the first rib, assessment of the lower trunk of the brachial plexus. Visualization of the Roos ligament, additional cervical rib, muscle abnormalities. Visualization of the subclavian brachial plexus - the level of the pectoralis minor tendon. Axillary level - bifurcation to the terminal branches.
