May "Dubel" be a solution for pullout problem of the pedicle screws at osteoporotic spine?

Aim: To improve the strength of stabilization systems currently used in osteoporotic spinal fractures, essentially by increasing the fixation force of pedicle screws.

Material And Methods: Six human cadaveric vertebrae were used. Bone mineral densities of the specimens were measured with Dual Energy X-ray Absorptiometry in order to assess the osteoporosis.

Massive congenital intracranial immature teratoma of the lateral ventricle with retro-orbital extension: a case report and review of the literature.

Germ cell tumors comprise 0.4-3.1% of all intracranial tumors, and teratoma constitutes 9-30% of them.
