title: [Ultrasonic anatomy and study technic of the normal carpal tunnel and the distal median nerve].
abstract: The wrists of 16 normal volunteers were examined via high-resolution sonography with special reference to the carpal tunnel. In all cases the surfaces of the carpal bones, the flexor retinaculum, the tendons, the vessels, (Aa. radialis and ulnaris) and the nerves (Nn. medianus and ulnaris) were observed. The sonographic characteristics of the median nerve are discussed and the possibilities of identification are demonstrated. It appears that the echogenicity of the nerve depends strongly on the angle of the ultrasound beam.
