Summary
A massive thoracic herniation caused rapid paraparesis in a 65-year-old male due to adjacent spinal instability after prior lumbar fusion surgery.
Area of Science:
- Spinal surgery
- Neurosurgery
- Orthopedic surgery
Background:
- Previous lumbar fusion with transpedicular instrumentation can lead to adjacent segment disease.
- Adjacent segment instability is a known complication following spinal fusion procedures.
Observation:
- A 65-year-old male presented with acute onset of incomplete paraparesis.
- The patient had undergone prior lumbar fusion with transpedicular instrumentation.
Findings:
- A massive thoracic herniation was identified as the cause of the patient's symptoms.
- The herniation occurred secondary to adjacent instability at the thoracolumbar junction.
Implications:
- This case highlights the potential for delayed complications, including massive disc herniation, at segments adjacent to spinal fusion.
- Early recognition and management of adjacent segment instability are crucial to prevent neurological deficits.
- Understanding the biomechanics of adjacent segment degeneration is important for surgical planning and patient outcomes.
