Fusion strategy after odontoid fracture and three-column atlantoaxial displacement in a patient with prior C2-pelvis fusion: a case report

This case highlights a surgical strategy for stabilizing complex cervical fractures in patients with previous extensive fusions and limited options for fixation while allowing minimal disruption of previous fusion masses and preexisting hardware. By extending the fusion to the occiput, using cervical pedicle screws, and integrating existing hardware, we achieved sound structural stability. This approach offers a potential fusion strategy for similar cases where preserving fusion integrity and spinal stability is critical amidst challenging anatomical constraints.
