Anterior interosseous nerve neuropathy in a patient with spinal cord injury: case report and literature review

Patients with spinal cord injuries often develop nerve entrapments, especially in the upper limbs, which can worsen their existing disabilities. This report describes a rare case of anterior interosseous nerve (AIN) neuropathy in a spinal cord injury patient. The patient, who had a spinal cord injury, experienced decreased thumb function. Doctors found that the AIN was compressed. Surgery was performed to relieve the compression. The surgical decompression led to improvement of the patient's symptoms, suggesting that surgery can be an effective treatment for AIN neuropathy in spinal cord injury patients.

• 1
  The patient with SCI was diagnosed with compressive AIN neuropathy through nerve conduction studies, electromyogram, ultrasonographic assessment, and magnetic resonance neurography.
• 2
  Surgical exploration and neurolysis resulted in improvement of the patient's symptoms, highlighting the potential effectiveness of surgical intervention for AIN neuropathy in SCI patients.
• 3
  The study emphasizes that entrapment neuropathies should be considered when evaluating SCI patients with new motor deficits, and electrophysiologic testing along with imaging are crucial for diagnosis.
