    Description / Table of Contents: Résumé Des différences significatives existent dans la description de la vascularisation de la partie inférieure du m. trapèze (“trapèze inférieur“), notamment du fait que ces descriptions ont été basées sur un très petit nombre de cas. Notre travail est basé sur l'étude de 70 sujets. Un rameau trapézien naissant de l'a. scapulaire dorsale a été retrouvé de façon constante. L'origine de l'a. scapulaire dorsale est toutefois variable : dans 45 % des cas, il s'agit d'une branche directe provenant soit de l'a. subclavière, soit du tronc costo-cervical. Dans les 55 % des cas restants, l'a. scapulaire dorsale constitue différents troncs avec l'a. cervicale superficielle et/ou l'a. suprascapulaire, l'a. subclavière, le tronc thyro-cervical, ou de l'a. thoracique interne. Des aa. perforantes musculo-cutanées participent également à la vascularisation du “trapèze inférieur” et de la peau sus-jacente. En conséquence, la partie inférieure du m. trapèze a une vascularisation de type V de Mathes et Nahai. Ainsi, le lambeau musculo-cutané du trapèze inférieur mérite une place de choix dans les reconstructions cervico-céphaliques.
    Notes: Summary Differences in the description of the blood supply of the lower trapezius m. and the fact that all former findings are based on very few cases caused us to reinvestigate the arterial supply of the lower trapezius m. Based on the anatomic investigation of 70 human cadavers, the trapezial branch of the dorsal scapular a. was found to be the constant vessel to the lower trapezius m. The origin of the dorsal scapular a., however, was found to be very variable. In 45% it was a direct branch of either the subclavian a. or the costocervical trunk. In the remaining 55% the dorsal scapular a. formed different trunks with the superficial cervical a. and/or supras-capular a. branching off either the subclavian a., the thyrocervical trunk, or the internal thoracic a. Additional segmental musculocutaneous perforators also supply the lower part of the trapezius m. and the overlying skin. Consequently, the lower or ascending part of the trapezius m. has a vascular pattern type V. Thus, the lower trapezius musculocutaneous flap merits consideration in head and neck reconstruction.

    Notes: Summary Stiff rod-like chain molecules with harmonic bond length potentials and trigonometric bond angle potentials are used to model Langmuir monolayers at high densities. One end of the rod-like molecules is strongly bound to a flat two-dimensional substrate which represents the air-water interface. A ground-state analysis is performed which suggests phase transitions between phases with and without collective uniform tilt. Large-scale off-lattice Monte Carlo simulations over a wide temperature range show in addition to the tilting transition the presence of a strongly constrained melting transition at high temperatures. The latter transition appears to be related to two-dimensional melting of the head group lattice. These findings show that the model contains both, two- and three-dimensional ergodicity breaking solidification transitions. We discuss our findings with respect to experiment.
