Abstract
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. 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.Keywords
