Axillary Mononeuropathy After the Flu Shot: A Case Report

Video Transcription

Video Summary

The presenter discusses a case report of axillary mononeuropathy after a flu shot. The axillary nerve, which originates from C5 to 6, travels through the brachial plexus and innervates the deltoid and teres minor muscles. Axillary neuropathy is typically caused by incorrect crutch use or fractures/dislocations. The 25-year-old patient in the case developed severe left shoulder pain and weakness after receiving the influenza vaccine in the same arm. Examination showed weakness in the left arm and EMG studies indicated increased insertional activity and reduced recruitment in the left deltoid. The presenter highlights the importance of considering axillary nerve involvement in patients with similar symptoms after injections or trauma to the area.
