This case report details a rare ligamentum flavum hematoma in the cervical spine, occurring 11 years after spinal instrumentation. Surgical evacuation proved effective for this delayed complication.
Area of Science:
- Neurosurgery
- Spinal Surgery
Background:
- Cervical spine instrumentation is a common procedure for spinal stability.
- Delayed complications after spinal surgery can occur, though rare.
Observation:
- A case of ligamentum flavum hematoma was identified 11 years post-cervical spine instrumentation.
- The hematoma was associated with sublaminar hooks used in the initial surgery.
Findings:
- 15 mL of subacute hematoma was evacuated from the ligamentum flavum.
- This represents the first reported instance of ligamentum flavum hematoma after cervical spine instrumentation.
Implications:
- Ligamentum flavum hematoma can manifest significantly late after spinal instrumentation.
- Surgical evacuation is the primary treatment for symptomatic cases.
- Meticulous dissection is crucial if spinal instruments adhere to surrounding tissues.
