Diagnostics

The diagnosis of peripheral nerve injuries is based on a thorough clinical history, neurological examination, and, in some cases, diagnostic tests (e.g., x-ray if fracture is suspected).

• Imaging

  • Plain x-ray: detection of compression or transection due to dislocated bone or fracture segments

  • CT/MRI: evaluation of causes like nerve tumors, avulsions, and focal soft tissue pathologies

• Electrodiagnostic studies: detect and grade nerve injury, nerve compression, and identify early stages of recovery

  • Electroneurography (nerve conduction study): analysis of a muscle's electrical activity in response to stimulation of its supplying nerve

  • Needle electromyography (EMG)
