Repair of symptomatic pseudoarthrosis of anterior cervical fusion. Posterior versus anterior repair.
Thirty-four patients with symptomatic pseudarthrosis of anterior cervical fusion were treated. There were 16 men and 18 women. Eighteen patients had pseudarthrosis at 1 level; 14 at 2 levels; and 2 at 3 levels, with C5-6 and C6-7 levels most commonly involved. Anterior repair of pseudarthrosis was done in 17 patients, which resulted in 76% radiologic fusion. Of 17 patients repaired posteriorly, 94% achieved radiologic fusion. Average follow-up was 60 months, with a minimum of 24 months. "Excellent" or "Good" results were achieved in 59% of anterior repair and 88% of posterior fusion group. This study demonstrates that posterior cervical fusion is the more effective method for repairing symptomatic pseudarthrosis of anterior cervical fusion.
