Multipoint fixation with vascularised fibular bone graft and myotomy for atlanto-axial instability in cervical...

Spinal instability is a challenging condition to manage in patients with cervical dystonia. Standard surgical stabilisation approaches may fail to cope with additional stress forces created by spasmodic muscles leading to construct failure either in the immediate or late post-operative period. Long-term stabilisation relies on the management of dystonic symptoms and adjunctive strategies to increase fusion success rate. We discuss the management of a challenging patient with translational C1/2 instability who had three metalwork failures with standard occipito-cervical fixation techniques within a 12 month period. A combined surgical approach using multipoint fixation, sternocleidomastoid myotomy and a vascularised fibular occiput-C2 bone graft successfully prevented further metalwork failure at over 2 years follow up.
