• The assessment of peripheral nerves in children with upper limb injuries can be challenging. 
• Neurovascular deficit was not documented in 25% of children presenting with upper extremity injury
• BOAST (British Orthopedic Association Standards for Trauma) guidelines state that each of the Median, Ulnar, Radial, Anterior Interosseous Nerve exams must be individually documented in any supracondylar fracture
• Dawson described an easy way to test and document your exam. Have the child play “Rock, Paper, Scissors, Ok”
  • Rock: tests the Median nerve
  • Paper: tests the Radial nerve
  • Scissors: tests the Ulnar nerve
  • Ok: tests the Anterior Interosseous nerve
• This method increased proper documentation and reduced missed nerve injuries in upper extremity fractures.
• Dr. Sarah Edwards and Dr. Hannah Lock created an easy infographic in the link below and found near 100% increase in NV documentation in their ED. Their poster won the prize for best infographic at the 2018 Emergency Medicine Educators' Conference (EMEC)
