title: Electrophysiological and ultrasonographic findings in ulnar neuropathy with Martin-Gruber anastomosis.
abstract: BACKGROUND
  It is important to understand the presence of Martin-Gruber anastomosis in patients with complete ulnar neuropathy at the elbow.
  
  
  METHODS
  We describe a patient with complete ulnar neuropathy at the elbow and Martin-Gruber anastomosis in the forearm, mimicking incomplete ulnar neuropathy with complete conduction block in the forearm segment. Ultrasonography of the ulnar nerve around the elbow demonstrated severe swelling of the ulnar nerve, which was compatible with severe ulnar neuropathy at the elbow.
  
  
  CONCLUSIONS
  This case report demonstrates that combination of ultrasonography with electrophysiological studies can provide more detailed information about the changes of nerve structures and lesion sites.
