    Description / Table of Contents: Résumé Etude en trois étapes de l'articulation métacarpo-phalangienne. D'abord, un goniomètre axial a été mis au point, permettant la mesure directe de la mobilité articulaire tant sur le vivant que sur le cadavre. Puis, grâce aux données ainsi recueillies, on a réalisé un modèle simulé par ordinateur de l'articulation. Ceci a permis l'analyse de l'orientation de l'articulation pour chaque point donné dans l'axe de la mobilité, de l'action des ligaments latéraux et de leur rôle dans la mobilité et la stabilité articulaire. Enfin, la tête du métacarpien a été étudiée à l'aide d'un fantôme et de dissections anatomiques. De 0° à 70°, la tête métacarpienne est incurvée. A 70° environ elle prend une forme bicondylienne qui constitute un butoir osseux empêchant les mouvements de latéralité. La dissection des ligaments latéraux a montré qu'ils suivent un trajet oblique depuis la tête du méta jusqu'à la première phalange. On en conclut que l'articulation MP a un axe instantané. De 0° à 70° de flexion, pour une main donnée, l'angle de déviation latérale est constant. Au delà de 70° il diminue notablement. L'articulation a deux degrés de liberté et les ligaments latéraux sont en tension dans toutes les positions.
    Notes: Summary A three stage study of the metacarpophalangeal joint was performed. First, a triaxial goniometer was designed which allowed direct measurement of joint motion in living and cadaveric hands. Then, based on the above data, a computer simulated model of the joint was developed. This permitted an analysis of the orientation of the joint for any given point in the axis of motion, the effects of the collateral ligaments and their contribution to joint motion and stability. Finally the metacarpal head was analysed using a shadow profilometer and anatomical dissections. From 0° to 70°, the metacarpal head demonstrated a curved configuration. At approximately 70°, the metacarpal head assumed a bicondylar shape which produced a bony block to lateral deviation. Dissection of the collateral ligaments demonstrated that they ran diagonally from the metacarpal head to the proximal phalanx. We conclude that the metacarpophalangeal joint has an instant axis. From 0° to 70° of flexion, in any given hand, the angle of lateral deviation is constant. Beyond 70° there is a marked decrease in lateral deviation. The joint has two degrees of freedom and the collateral ligament is taut in all positions.

    Description / Table of Contents: Résumé Le but de ce travail est d'étudier les effets thermiques de la polymérisation sur les petits os longs. Les résultats montrent seulement, durant la prise du ciment, une élevation modérée de la température dans la cavité médullaire de ces os. L'élévation maximale (11° 7) est dans les limites de tolérance des cellules osseuses vivantes. Il a été démontré que les petites quantités de méthyl-métacrylate refroidissent plus rapidement, donc que diminuent davantage les effets nuisibles de la chaleur. Les examens histologiques ne montrent aucune altération due aux effets thermiques de la polymérisation du méthyl-métacrylate sur les petits os longs ni sur les tissus de recouvrement.
    Notes: Summary This study was designed to investigate the thermal effects of polymerization on small tubular bones. The results demonstrated only a slight increase in temperature during cement-curing in the medullary canals of these bones. The maximum rise (11.7° C) was within the levels of tolerance for living bone cells. It was demonstrated that the small volumes of methyl-methacrylate cool more rapidly, hence further decreasing the deleterious effects of heat. The histological studies showed no recognisable adverse reaction to the thermal effects of methyl-methacrylate polymerization on small tubular bones or on the overlying tissue.
