pronator syndrome

, Pronator teres syndrome
A neurological disorder caused by entrapment of the median nerve at the elbow. Symptoms and signs include aching in the wrist with a subjective feeling of poor coordination; paresthesias extending into the hand; paresis of the thumb muscles; pain on pronation of the forearm and flexion of the wrist against resistance; and tenderness in the proximal thenar muscles. A positive Tinel's sign over the pronator teres muscles may be present. The disease usually affects the dominant arm in men. The condition may be treated with corticosteroid injections or orthopedic surgery.

The knowledge of its innervation to pronator teres is of utmost importance in understanding the several presentation of pronator teres syndrome, in investigating the median nerve lesions, to design satisfactory treatment, and to avoid iatrogenic injuries during operations.
Carpal tunnel syndrome, pronator teres syndrome and anterior interosseous syndrome are three well described entrapment syndromes involving the median nerve or its branches.
CONCLUSION: Although the incidence of AHFPL is variable among the different races, (10) it can be one of the cause for AIN syndrome, pronator teres syndrome, carpel tunnel syndrome, or abnormal sensation in the lower part of the forearm.
The exclusion criteria consisted of (i) history of wrist trauma, rheumatic disease, acromegaly, hypothyroidism, pregnancy, or prominent orthopedic abnormalities; (ii) the absence of motor or sensory potentials of the median nerve; and (iii) various other disorders resembling CTS such as cervical radiculopathy, brachial plexopathy, pronator teres syndrome and polyneuropathy.
