Summary
Post-traumatic syringomyelia, a complex spinal cord disorder, can result from trauma. Surgical decompression and spinal alignment effectively resolved a patient's severe neurological deficits.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- Posttraumatic syringomyelia is a complex spinal cord disorder with unclear etiology.
- Hypotheses exist, but no consensus on its pathogenesis has been reached.
- This case explores a specific etiology involving bony obstruction and spinal deformity.
Observation:
- A 28-year-old male presented with progressive lower extremity weakness and sensory loss below T4, five years post-trauma.
- MRI revealed a large syrinx from C5 to L1 and a retropulsed L2 bony fragment.
- Symptoms included bilateral leg weakness and dysesthesia.
Findings:
- Surgical intervention included L2 corpectomy, L1-L3 interbody fusion, and ventral spinal cord decompression.
- Postoperative MRI confirmed syrinx collapse and restored cerebrospinal fluid (CSF) flow.
- The patient experienced complete resolution of neurological symptoms.
Implications:
- Syringomyelia can develop due to subarachnoid CSF space obstruction by bony fractures and kyphosis.
- Ventral decompression and spinal realignment effectively treat spinal canal encroachment and post-traumatic syringomyelia.
- Surgical restoration of CSF flow correlates with symptomatic improvement in these cases.
