 Most common entrapment neuropathy  Causes  Thickening of synovium  Frequent anatomic variations

 Function  Attachments  Contents  Closed compartment  Site marking  Deep antebrachial fascia and palmar aponeurosis  Anomalous muscle  Narrowest and thickest portion

 Roots  Sensory  Motor  Course in forearm  Palmar cutaneous branch  Position in flexion and extension  Terminal branches  Origin and penetration of thenar branch

 Digital nerves  Lumbricals  Ulnar to thenar crease

 Palmar arches  Marking  Communicating branch between sensory parts of median and ulnar nerve  Deep branch of ulnar nerve

 Extreme radial to anterior  20% anomalous origin  12.5% multiple motor branches  56% separate tunnel

 Duplication of motor br + thin sensory branch  Transligamentous to abductor, opponens , extraligamentous to flexor  Accessory sensory br with TCDN arising proximally

 Between ulnar and median nerve in forearm  Rarely in distal forearm and palm  Variations  Subtypes
