    Description / Table of Contents: Résumé Cette étude porte sur le rameau dorsal du deuxième n. spinal cervical (ou grand n. occipital d'Arnold); nous avons voulu préciser, par des dissections sur cadavres formolés, le trajet sinueux de ce nerf, en essayant de le situer par rapport à des repères cliniques ou radiographiques, ceci afin de guider au mieux des infiltrations de ce nerf. De façon concomitante, il a été réalisé une étude dynamique pour reconnaître les rapports du nerf avec les éléments l'entourant lors des divers mouvements du cou, ce qui peut conduire à proposer des manœuvres cliniques sensibilisant les conflits et faisant apparaître les zones de vulnérabilité du nerf.
    Notes: Summary This study concerns the posterior ramus of the second cervical spinal n., or greater occipital of Arnold. By means of dissections in formalin embalmed cadavers, an attempt was made to define its winding course and to locate it in relation to clinical or radiographic landmarks, so as to provide a guide for infiltration of the nerve with local anesthetic. At the same time a dynamic study was made to elucidate the relations of the nerve to adjacent structures during the different movements of the neck. This allowed us to propose clinical tests of nerve involvement and to reveal the zones where the nerve is anatomically vulnerable.

    Notes: Summary Thirty-three patients with recurrent sciatica after lumbar-disk surgery were studied for recurrent herniated nucleus pulposus (HNP) by CT alone and CT-diskography (CTD). Twenty-six patients underwent surgical reexploration allowing correlation with CTD. CTD made a correct diagnosis of recurrent HNP in twenty-one patients showing an extravasation of the contrast medium from the disk space into the medullary canal. In two cases CTD was positive for recurrent HNP but surgery showed only fibrosis. The amount of contrast leak was very small in these two cases along the posterior common longitudinal ligament, and the junction with the disk was very narrow. Because of their clinical presentation three patients with negative studies were operated upon. One showed only fibrosis and the two others showed an associated disk fragment. Among the twenty-one true-positive cases, seven showed a combination of recurrent HNP and scarring. Contamination of CSF by the contrast medium through the dura was observed in two patients. Although a prospective comparative study between CTD and IV-contrast-enhanced CT is necessary, CTD appears to be a useful diagnostic procedure for recurrent HNP after surgery of the lumbar spine.
