Brief summary: In patients with cervical spine disorders or hernia, in-line stabilization and immobilization during tracheal intubation is used to avoid neck injury. With direct laryngoscopy cranio-cervical motion can result injury. The aim of the study is to compare two different device (C-Mac D blade versus fastrach LMA ) regarding cervical motions during intubation.

Detailed description: In simulated or clinical settings of restricted neck mobility, videolaryngoscopes and fastrach LMA have performed well but neck motion can be occured. Endotracheal intubation will be performed under fluoroscopy. In this study the neck motion angles will be investigated during intubation . The angles will be assessed on fluoroscopy images. A Angle: Angle of the line between occipital protuberance and anterior process of the foramen magnum with the line between central point of spinous process C1 vertebrae and the anterior process of foramen magnum. The reference line for the occiput is defined as a line between the base of the sella and the opisthion (lineA), and the C1 reference line as a line between the lower cortical margin of the spinous process (line B). The C2 reference line is defined as a line between the anterior , inferior margin of the C2 body and the lower cortical margin of the C2 spinous process (lineC). The C5 reference line is a tangent along the superior endplate of the C5 vertebral body (line D). The groups will be compared statistically.
