Radial nerve
• Largest branch of brachial plexus
• Roots C5,6,7,8 and T1
• Least common nerve to be compressed

Sites of Compression
• Axilla
• Mid-humeral
• Elbow
• Distal forearm

Axillary
• Saturday night palsy• Honeymooner’s palsy• Crutches
• Preceding pain• Transient

Mid-humeral
• Trauma• most common cause• fracture• penetrating injury
• Exploration v conservative
![Page 13: Radial Nerve Compression Graham Chuter SpR Teaching, RVI April 2007](https://reader035.vdocuments.mx/reader035/viewer/2022070416/56649d455503460f94a22639/html5/thumbnails/13.jpg)
Elbow
• Most common site
• Radial tunnel syndrome• local structures
• PIN syndrome• supinator entrapment• level-dependent

Forearm
• Superficial radial nerve entrapment• brachioradialis and ECRL• repetitive pronation /
supination• 50% assoc with
De Quervain’s
• Pain and paraesthesia
• 1932: Wartenberg’s Syndrome

Summary
• Revision of anatomy
• 4 main sites of compression / injury• axillary• humeral• elbow• forearm
• Surgery only after failed conservative Rx
