Summary
A rare complication of spinal fusion, a rotated rod penetrated the dura causing pain and flexion contractures. Surgical removal of the penetrating rod segment resolved symptoms, highlighting the need for preventative measures in spinal instrumentation.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Fusion Techniques
Background:
- Posterior spine fusion with interspinous process segmental spinal instrumentation is a common procedure.
- Complications, though rare, can significantly impact patient outcomes.
- Understanding potential adverse events is crucial for surgical planning and patient safety.
Observation:
- A case of pseudo-meningocele developed after posterior spine fusion.
- The spinal instrumentation rod rotated 90 degrees postoperatively.
- The rotated rod penetrated the dura mater, leading to neurological compromise.
Findings:
- The patient presented with severe pain and fixed lumbar and hip flexion contractures.
- Surgical intervention involved the removal of the penetrating rod segment.
- Dramatic improvement in pain and contractures was observed after the removal.
Implications:
- This case highlights a rare but serious complication of spinal instrumentation.
- Prompt diagnosis and surgical management are essential for favorable outcomes.
- Recommendations for prevention strategies during posterior spine fusion are discussed.
