    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.

    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.
