Description
Wrist injections risk nicking a sensory nerve, so So Hyun Park and co-authors mapped that nerve with ultrasound in a 2026 study. They scanned 58 forearms from 29 healthy volunteers, tracing the superficial radial nerve across four landmarks near the wrist extensor compartments.
Forearm length predicted the nerve's position at proximal landmarks but not at the most distal one. For intersection syndrome, the team identified a safer corridor between 24.1% and 12.7% of forearm length, approached from the thumb side downward. For De Quervain's tenosynovitis, they advise a volar-to-dorsal needle path at or beyond 0.8 cm from the radial styloid. The landmark mix aims to cut accidental nerve injury.
