Posterior upper cervical fusion in rheumatoid arthritis.
The purpose of this study was to determine fusion rates in patients who underwent posterior cervical fusion for instability of the upper cervical spine secondary to rheumatoid arthritis. A retrospective review of clinical and radiographic data was conducted. Nineteen patients underwent posterior cervical fusions limited to the upper cervical spine. There were 11 C1-C2 fusions and 8 occiput-C2 fusions. Instability with pain or neurologic deficits were the main indications. A uniform technique was used in all cases. Preoperative reduction in halo vest or cast was followed by a Gallie type fusion using autogenous iliac bone graft and wire, and postoperative halo vest or cast immobilization for 3 months. A fusion rate of 94% was achieved. The average follow-up was 5 years. Complete or partial relief of pain was obtained in all patients; 30% of those with preoperative deficits improved after surgery. A high fusion rate may be achieved with C1-C2 and occiput-C2 fusions in rheumatoid arthritis, with relief of pain and prevention of neurologic deterioration.
