Historic origin of the "Arcade of Struthers".
John Struthers wrote in 1848 and 1854 about sites of compression of the median nerve from axilla to elbow. He is best known for describing the rare median nerve entrapment by a ligament from a supracondylar process extending to the medial humeral epicondyle. In 1973, observation of ulnar nerve entrapment associated with a midshaft humeral fracture and subsequent anatomic dissections led to the creation of the term "Arcade of Struthers." Review of Struthers' original writings fails to identify either the use of word "arcade" or description of ulnar nerve compression. Review of published anatomic dissections identifies variations in the origin of the medial head of the triceps, not described by Struthers, that may cause failure of an anterior transposition of the ulnar nerve. Continued use of the term "Arcade of Struthers" is historically incorrect.
