Combined anterior interbody fusion and posterior pedicle screw fixation in patients with degenerative lumbar disc disease

We reviewed 47 consecutive patients with degenerative lumbar disc disease. All patients were treated by anterior interbody fusion using an autogenous iliac bone graft in combination with posterior pedicle fixation but without a posterior fusion. There were 32 men and 15 women with a mean age of 44 (range 23-56) years. One third (n=15) of the patients had previous surgery. We saw complications in six patients including two with vascular injury. The mean follow-up was 2.2 years. Seventy-two per cent of the cases had a satisfactory clinical outcome, and the overall fusion rate was 97%.
