Electrodiagnosis in post-traumatic syringomyelia

Area of Science:

• Neuroscience
• Neurology
• Clinical Electrophysiology

Background:

• Syrinx development years after spinal cord trauma is recognized.
• Previous studies detail clinical presentations, diagnostic methods like myelography, surgical outcomes, and autopsy findings.
• Surgical intervention is often believed to halt or reverse syrinx progression.

Observation:

• This study examines electrodiagnostic findings in three patients with post-traumatic syrinx.
• It compares these findings with electrodiagnostic changes in a spinal cord injury patient with worsening symptoms from other causes.
• Electrodiagnostic changes in two patients with non-traumatic cervical syringomyelia are also analyzed.

Findings:

• Electromyography (EMG) can be a valuable tool for diagnosing spinal cord syrinx.
• Interpreting EMG in patients with prior spinal cord trauma, including post-surgical cases, presents challenges.
• The study highlights specific electrodiagnostic patterns associated with post-traumatic syrinx.

Implications:

• Accurate and early diagnosis of syrinx is paramount for effective management.
• Electromyography, when used judiciously, can be an important adjunct for diagnosis and prognosis.
• Understanding these electrodiagnostic findings may improve patient outcomes and treatment strategies.
