Background: Jefferson fractures are burst fractures involving both the anterior and posterior arches of C1. They typically result from axial compression or hyperextension injuries. Most are stable, and neurological deficits are rare. They are often successfully treated with external immobilization, but require surgery (e.g., fusion/ stabilization).
Case description: An 89-year-old male presented with a left-sided hemiplegia following a trivial fall. The cervical computed tomography scan revealed a left-sided displaced comminuted C1 fracture involving the arch and lateral mass. The MR revealed posterior cord compression and focal myelomalacia. Six months following an emergent C1-C3 decompression with occiput to C4 instrumented fusion, the patient was neurologically intact and pain-free.
Conclusion: An 89-year-old male presented with a left-sided hemiplegia due to a Type 3/4 C1 Jefferson fracture. Following posterior C1-C3 surgical decompression with C0-C4 instrumented fusion, the patient sustained a complete bilateral motor recovery.
