Variations and Lesions of the Brachial Plexus at the Level of Nerve Fascicles
摘要
Damage to the posterior fascicle affects the axillary and radial nerves. The lesions of the medial fascicle (median, ulnar, and medial cutaneous brachial nerves) affect the flexion in the wrist and proximal (II.–IV.) and distal (II.–III.) interphalangeal finger joints. The damage to the lateral fascicle affects the musculocutaneous and partly the median nerves. The observed brachial plexus variations at the level of fascicles are shown in the table and discussed.
