Study Notes
Radial Nerve Injury
-
Radial nerve injuries distal to the elbow can result from:
- Elbow dislocations
- Elbow fractures
- Tight casts/compressive wraps
- Rheumatoid conditions/inflammatory arthritis
-
These injuries cause weakness in extending the hand and fingers, and can lead to finger drop and partial wrist drop.
Wartenberg's Syndrome
- This is the entrapment of the radial nerve's superficial branch.
- Patients experience pain over the distal radial forearm.
- Pain is often accompanied by paresthesia (prickly, burning sensation) over the dorsal radial hand.
