What are the manifestations of radial nerve injury

summary

Trauma, surgical injury and other factors can cause radial nerve injury, to clear the symptoms of radial nerve injury, timely treatment when found. Let's take a look at the manifestations of radial nerve injury.

What are the manifestations of radial nerve injury

Symptom 1: when the radial nerve of upper arm is injured, all extensors are paralyzed, triceps brachii, brachioradialis, extensor carpi radialis, pronator, extensor digitorum communis, extensor carpi ulnaris ulnaris and extensor digitorum propria are paralyzed. Therefore, there are wrist ptosis, thumb and fingers ptosis, unable to extend metacarpophalangeal joint, forearm pronation deformity, unable to supination, thumb adduction deformity. Triceps brachii and extensor carpi should be examined in the direction of anti gravity.

Symptom 2: the thumb loses abduction, the metacarpophalangeal joint cannot be stabilized, and the thumb function is seriously impaired. Because of the paralysis of extensor carpi ulnaris and extensor carpi radialis, it is difficult to move the wrist to both sides. The muscle atrophy of the dorsal forearm was obvious. In the dorsum of forearm, radial nerve injury was mostly interosseous dorsal nerve injury, sensation and triceps brachii, posterior elbow muscle were not affected, extensor carpi longus radialis was good. The other extensors were paralyzed.

Symptom 3: after radial nerve injury, sensory disturbance occurs in the radial half of the dorsum of the hand, the two half fingers of the radial side, the upper arm and the back of the forearm.

matters needing attention

Pay attention to avoid heavy physical labor, avoid aggravation, can be local hot compress massage therapy, application of mecobalamin, vitamin B1 and other neurotrophic drugs, if the situation is more serious, then need to go to surgery for further treatment.
