[Anterior interbody fusion with neurological symptoms of a spondylolisthesis (author's transl)].

28 patients with spondylolisthesis who underwent anterior interbody fusion at the Orthopaedic Department of the University of Basle between 1968 and 1976, have been follow-up. In 90% satisfactory or good clinical results were achieved. In 82% the neurological symptoms - without laminectomy - were markedly improved or eliminated. According to the authors anterior interbody fusion (with reduction and enlargement of the intervetebral space) is indicated even when neurological symptoms are present.
