Meningism
  • Traumatic nerve root avulsion occurs when traction forces pull the nerve root sleeve into the intervertebral foramen with associated tearing of the meninges.[ncbi.nlm.nih.gov]

Workup

  • Order a neurologic evaluation to recommend further workup and to establish baseline loss of function so that improvement may be monitored.[pedclerk.bsd.uchicago.edu]

  • Early recognition and treatment can have improved outcomes for patients.[hss.edu]

Prognosis

  • Prognosis Spontaneous recovery occurs in almost 90% of cases. This is because upper injuries, e.g., Erb’s Palsy(C5, C6), have the best prognosis and account for 90% of all brachial plexus injuries.[pedclerk.bsd.uchicago.edu]
  • Motor evaluation of the patient is essential as it is indicative of prognosis and helps to guide therapy.[blog.dinopt.com]
