The role of external transpedicular fixation in anterior interbody lumbar fusion.

The aim of this study was to see whether results of anterior interbody lumbar fusion could be improved with the help of an external transpedicular device. Anterior interbody lumbar fusion was carried out in 83 patients, using the technique described by Suzuki. Fifty-six (67%) patients were fused with the Magerl-Schläpfer external fixator device as a posterior support. Twenty-seven patients had interbody fusion and a conventional plastic brace for support. The clinical and radiological results of anterior interbody lumbar fusion were compared between these groups. The mean follow-up time was 5 (range, 2-10) years. A total of 128 levels were fused. There were no statistical differences in the clinical and radiological results between patients fused with or without the external fixator. There were many complications associated with the use of an external fixator device. We do not recommend the use of an external fixator in anterior interbody lumbar fusion.
