Syndromes of compression of the median nerve in the proximal forearm (
pronator teres syndrome; anterior interosseous nerve syndrome).
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
pronator teres syndrome results in median nerve compression in the proximal 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.
