[Post-traumatic ulnar nerve irritation and paralysis as a compression syndrome under the palmar carpal ligament].

The palmar carpal ligament is defined as the distal border of the fascia antebrachii. It is proposed that this name is not used for the region of the fascia antebrachii proximally to this structure or for parts of the retinaculum distal to this structure, i.e. in the hypothenar region. The palmar carpal ligament has been found to be a cause of posttraumatic irritation of the ulnar and median nerve at the wrist proximal to the carpal tunnel or Guyon's canal.
