Cubital Tunnel-Guyons Canal

Video Transcription

Video Summary

The video discusses the anatomy and compression of the ulnar nerve at Guillon's Canal. It explains that Guillon's Canal is a distinct anatomic space located slightly ulnar to the carpal tunnel. It was originally described by Guillon in 1861 and subsequent research has further characterized its anatomy. The video highlights the different zones of Guillon's Canal, symptoms of ulnar nerve compression, and various causes, including ganglion and ulnar artery aneurysm. The speaker emphasizes the importance of proper diagnosis through physical examination, imaging, and electrodiagnostic testing. Surgical decompression is recommended in cases that do not respond to conservative treatment, with a focus on releasing the whole tunnel and preserving important motor branches.
