title: Superficial radial sensory neuropathy: Medial and lateral branch injury.
abstract: BACKGROUND
  Superficial radial sensory nerve (SRN) injury may involve the main nerve or its distal medial or lateral branch. We investigated the utility of SRN conduction studies on the medial and lateral branches in patients with suspected SRN injury.
  
  
  METHODS
  Fifteen patients with symptoms of SRN neuropathy were studied. Their clinical and electrophysiological findings were assessed according to sensory symptom areas. Three active recording electrode positions were used: snuff box (position A); medial branch (position B); and lateral branch (position C).
  
  
  RESULTS
  In 7 patients with medial area symptoms, abnormal findings were seen in position B (100%) and position A (71%). In 3 patients with medial and lateral area symptoms, abnormal findings were seen in all positions. In 5 patients with lateral symptoms, abnormal findings were seen in position C only.
  
  
  CONCLUSIONS
  Nerve conduction studies for each branch of the SRN are useful in patients with suspected SRN neuropathy.
