Pronator Teres Syndrome

Pronator teres syndrome is entrapment of the median nerve in the proximal forearm (under pronator teres/ligament of Struthers/lacertus fibrosus), causing volar forearm pain and median-distribution hand numbness, distinguished from carpal tunnel by symptoms in the forearm and negative Phalen. Treatment: activity modification/PT, anti-inflammatories; surgical decompression in severe/refractory cases.

Common Symptoms

Volar forearm pain; median-distribution hand numbness; worse with pronation; negative Phalen

Causes and Pathogenesis

Median nerve entrapped at proximal forearm (pronator/lacertus fibrosus), producing pain and median-distribution numbness.

Treatment

Activity modification/PT; anti-inflammatories; surgical decompression if severe

Preventive Measures

Avoid repetitive pronation; ergonomics; PT.
