    Notes: Abstract The ligamentum flavum, of which there are only a few studies in the literature, has several features discussed in this work. On the macroscopic level, it has a metameric arrangement it has two layers, superficial and deep, whose fibers are oppposite, and it has close relations with the tendons of attachment of some spinal erector muscles. On the microscopic level, its structure is unique for a ligament, because of a predominance of elastic fibers, because of its intrinsic innervation at each level of the spine, and because this innervation grows poorer with increasing degeneration. The ligamentum flavum constitutes an active ligament, with an essential biomechanical role. Its injury is probably not without consequences, and therefore there are many technical problems about the surgical interlaminar approach.

    Description / Table of Contents: Résumé Le lig. jaune (ligamentum flavum), dont peu d'études sont rapportées dans la littérature, a plusieurs particularités mises en évidence dans ce travail. Sur le plan macroscopique, il a une disposition métamérique, il est composé de deux feuillets dont les fibres sont de direction opposée, il entretient des rapports étroits avec certains tendons d'insertion des mm. érecteurs du rachis. Sur le plan microscopique, sa structure est particulière pour un ligament, car y prédominent les fibres élastiques; une innervation lui est propre à chaque niveau vertébral, cette innervation s'appauvrit au fur et à mesure qu'augmente la dégénérescence ligamentaire. Le lig. jaune constitue un système ligamentaire actif, avec un rôle biomécanique essentiel. Le léser n'est sans doute pas sans conséquence, et cela pose des questions techniques concernant les abords chirurgicaux interlamaires.
    Notes: Summary The ligamentum flavum, of which there are only a few studies in the literature, has several features discussed in this work. On the macroscopic level, it has a metameric arrangement: it has two layers, superficial and deep, whose fibers are opposite, and it has close relations with the tendons of attachment of some spinal erector muscles. On the microscopic level, its structure is unique for a ligament, because of a predominance of elastic fibers, because of its intrinsic innervation at each level of the spine, and because this innervation grows poorer with increasing degeneration. The ligamentum flavum constitutes an active ligament, with an essential biomechanical role. Its injury is probably not without consequences, and therefore there are many technical problems about the surgical interlaminar approach.

    Notes: Summary The authors present a retrospective study of 535 consecutive anterior approaches to the cervical spine back to 5 years. The data were analyzed for post-operative complications. This surgical procedure has been commonly used for more than 40 years, but the post-operative complications due to the anterior approach itself were presented with few accompanying statistics, with various and contradictory results. Injury to nearly all of the structures has been reported in the literature, the more frequent problems are hoarseness and dysphagia; other complications include perforation of the oesophagus, hematomas, vascular injury⋯ Analysis of this data allows to understand better the specific problems related to this surgical approach, and to suggest precautions at each stage of the course of exposure of cervical vertebrae.

    Description / Table of Contents: Résumé Les suites de la chirurgie du rachis cervical par voie antérieure présternocléidomastoïdienne sont marquées dans un nombre de cas non négligeable par des troubles de la déglutition et de la phonation, et ce, d'autant que l'abord est étendu. 35 dissections sur cadavres ont été réalisées afin de préciser la topographie par rapport aux niveaux vertébraux, le trajet et les variations des éléments nerveux rencontrés lors de cet abord cervical : nerfs laryngés supérieur et récurrent, nerf hypoglosse et la racine supérieure de l'anse cervicale. A partir de cette étude morphologique, les auteurs suggèrent quelques points d' amélioration technique, à chacune des étapes de la dissection, en pratique chirurgicale.
    Notes: Summary The results of the surgical anterior approach to the cervical spine are marked in a number of cases by dysphagia and dysphonia, especially when the approach is extensive or performed at the upper cervical spine. 35 cadaver dissections were performed to define the topography of the nerve structures during operative exposure at various vertebral levels : superior and recurrent laryngeal nerves, hypoglossal nerve and its superior root of the ansa cervicalis. The authors suggest some technical improvements, for each stage of surgical dissection.

    Description / Table of Contents: Résumé Les auteurs ont réalisé une étude biométrique comparative des corps vertébraux cervicaux, en fonction du sexe et de l'âge, à partir de radiographies de la colonne cervicale de profil pratiquées chez 120 individus. On retrouve le dimorphisme sexuel net, déjà décrit par plusieurs auteurs. Les corps vertébraux de C2, C3 et C7 sont ceux dont la structure varie le plus avec l'âge. Les résultats de nos mesures sont en accord avec les constatations cliniques et précisent les données sur les changements structuraux de la colonne cervicale au cours du vieillissement. D'un point de vue plus strictement anthropologique, le corps vertébral de l'axis et plus précisément son diamètre sagittal, est le meilleur indicateur d'âge, indépendamment des facteurs extérieurs et individuels.
    Notes: Summary A biometric comparative roentgenological study of the cervical vertebral bodies was performed, according to age and sex, from lateral roentgenograms of 120 adult cervical regions. The sexual dimorphism already described by many authors was confirmed. The vertebral bodies of C2, C3, and C7 have the more variable structure according to age. The results of our measurements are in accordance with clinical findings and provide data on the structural changes of the cervical spine during ageing. In anthropological terms, the vertebral body of C2, in particular its antero-posterior diameter, is the best age indicator, irrespective of individual and exterior variables.
