Radial nerve

At the Axilla

Loss of extensors at the elbow, wrist, and digits; weakened extension at the shoulder; weakened supination. Sensory loss on posterior arm, forearm, and hand. Sign is "wrist drop." Shoulder dislocation may injure the radial nerve. Also, pressure on the floor of axilla may injure nerve (Saturday night palsy).

At the Elbow

Loss of extensors at the wrist and digits. Sensory loss on the posterior forearm and hand. Sign is "wrist drop." Fracture of the shaft of the humerus could lacerate the radial nerve, and the deficits would be the same as if the nerve were damaged at the level of the elbow.

At the Wrist

Sensory loss on the posterior hand (first dorsal web space).
