Myelopathy Improvement Following Removal of Cervical Sublaminar Wiring

Posterior cervical wiring has been used by spine surgeons in fixation procedures for patients with spinal instability. It is historically considered an effective method of treating cervical instability with a low risk of complications leading to neurological deterioration. We experienced a case of delayed neurological decline associated with myelopathy, lower extremity spasticity, and associated syringomyelia secondary to instrumentation failure and resultant sublaminar wire protrusion into the cervical spinal cord. In the present case, the construct was removed and the patient underwent a durotomy repair and a posterior fusion of cervical levels 1 and 2 via screw placement under image guidance with a subsequent functional improvement back to baseline. We report this case and review the literature on the complications associated with cervical wire fusion and the methods of minimizing these risks.
