STUDY DESIGN Retrospective study. PURPOSE To analyze the quantitative anatomy of C7 vertebra for insertion of lateral mass screws and pedicle screws in Southern Chinese patients. OVERVIEW OF LITERATURE C7 lateral mass is smaller when compared to other subaxial cervical levels, which limits the length of lateral mass screws that can be used. Some studies have suggested pedicle screws for bet...

In free-flap surgery, if the appropriate length of the pedicle and the distance necessary for separation of the artery and vein are determined earlier during flap elevation, the operative time and the stress placed on the flap pedicle can be reduced. However, the pedicle of a flap passes through 3-dimensional structures, particularly in head and neck reconstructions, and because of the differen...

Suitable selection of cultivars, is one of the important determinant factors that affects on quantity and quality of bulb flowers at the climate of Iran. In order to, introducing superior cultivars of gladiolus for cultivation in temperate regions of Iran, the experiment was carried out in a complete randomized block design (CRBD) in three replications with five cultivars of gladiolus including...
