[Surgical posterior approach in spondylolisthesis (author's transl)]

The authors report their experience about 60 patients who suffered of a spondylolisthesis and who were treated by a surgical procedure. A posterior approach has been used for all the patients. After a brief review of the clinical and radiological features of the disease, the authors emphazise the advantages of the posterior approach; only this technique allows a correct access both to the bone and the nerve roots lesions. Two types of operations are proposed:--the ablation of the posterior arch of the concerned vertebra (Gill's operation).--a posterior arthrodesis by mean of an homograft, using one of the following technique: an Albee grafting a Bosworth grafting an ilio-transversary grafting. The results are considered from a clinical, and an anatomo-radiological point of view.
