Historical note and terminology
After carpal tunnel syndrome, the most common median nerve entrapment is the pronator teres syndrome (Gessini et al 1983). Other less common entrapment sites include the ligament of Struthers, lacertus fibrosus, and the tendinous origin of the flexor digitorum superficialis.Lund 1930). Anterior interosseous neuropathy was originally described in 2 patients who had spontaneous recovery (Kiloh and Nevin 1952). Around the same time, the pronator teres syndrome was recognized (Seyffarth 1951). Median nerve entrapment under the bicipital aponeurosis was described over 2 decades ago (Koppel and Thompson 1976).
