Clinical signs and treatment of palsy of median, ulnar and radial nerves
1. Big picture
The median, ulnar, and radial nerves are the three major peripheral nerves of the upper limb. Their lesions are very exam-relevant because each gives a characteristic hand posture, movement deficit, sensory loss, and named sign.
The fastest way to recognize them:
| Nerve | Classic deficit | Classic hand sign |
|---|---|---|
| Median nerve | Loss of thumb opposition, thenar weakness | Ape hand / benediction sign |
| Ulnar nerve | Interossei weakness, finger abduction/adduction weakness |
