Answer

Campbell [41] and Halikis et al [29] agreed with Posner in listing this region as the final entrapment site in the elbow area. As the nerve exits the flexor carpi ulnaris, it perforates a fascial layer between the flexor digitorum superficialis and the flexor digitorum profundus. Entrapment can occur here also.
