Carpal tunnel

Dynamic scanning of the carpal tunnel during acitve flexion and extension of the fingers.
Hand wrist palmar carpal tunnel proximal transverse
Hand wrist palmar distal transverse

mn: median nerve

fpl: flexor pollicis longus tendon

ua: ulnar artery

fds: flexor digitorum superficialis tendons

fcr: flexor carpi radialis tendon

fdp: flexor digitorum profundus tendons

mbun: main branch of ulnar nerve

note: tilting the probe helps to avoid anisotropy and to check the structures within the carpal tunnel. Use dynamic scanning (flexion and extension of the fingers) to assess the nine long flexor tendons (flexor digitorum superficialis, flexor digitorum profundus and flexor pollicis longus radially).
