- Abstract
- (en) [Paresthesia of the hand] Paresthesias are most often evidence of compressive neuropathy on a path of innervation of the hand. Compression of the median nerve in the carpal tunnel is the most common, followed by compression of the ulnar nerve in the cubital tunnel at the elbow. More rarely, the median nerve is compressed at the arcade of the pronator teres in the forearm and the ulnar nerve in the Guyon tunnel at the wrist. Other compression sites, also affecting the radial nerve, mainly under fibrocomuscular arches (distributed from the thoracic outlet to the distal part of the limb), as well as cervical root compressions may also cause paresthesia. Diagnosis, essentially clinical, can be helped particularly by electromyography and ultrasound. The treatment is usually conservative in early stages, avoiding stress on the nerve and by infiltration of corticosteroids. In case of persistence, the decompressive surgery gives good results and prevents sequelae if it is practiced sufficiently early.
