ABSTRACT

Pronator syndrome is defined as the compression of the median nerve in the forearm, as it passes between the two heads of the pronator teres muscle or under the proximal edge of the arch of the flexor digitorum superficialis. Furthermore there may be said compression supracondylar region as a bone process or ligaments, named ligament Struthers, resulting in various symptoms as pain in forearm, with sensory impairment (paresthesia) in the distribution medium hand nerve and cutaneous distribution palmar thenar and can sometimes decrease the force. Frequently accompanies carpal tunnel syndrome. There are different methods of imaging and electrical conduction that can support the diagnosis. Plain radiography its efficiency, if you suspect a bone supracondylar process. Ultrasound gains value when compression is generated by masses such as tumors or hematomas; similar case with magnetic resonance imaging. But the latter, at cost, is not routinely used. Electromyography is of little diagnostic value, because its sensitivity only reaches 10% of cases. Conservative management is suggested initial form, but if the symptoms persist for three to six months, or be an established diagnosis, surgical management is suggested. There are different techniques ranging from low to incision endoscopic technique. All percentages generally exhibiting positive in 90% of patients.
