[Ventral support in dorsal lumbar fusion surgery : A case report with many incidents].

Anterior column support in posterior lumbar fusion surgery is essential for the outcome of the operation, particularly in the case of unstable pathologies such as spondylolisthesis or spondylodiscitis. The complicated case of a patient with simultaneous spondylolisthesis and spondylodiscitis is presented and reevaluated based on the literature and our own treatment algorithm. In the case of spondylodiscitis alone, iliac crest interposal is sufficient as a support. In the case of additional disturbances of the sagittal profile, a cage implantation is preferred.
