While performing the anterior approach to the cervical vertebral bodies, injury to important anatomic structures in the vicinity of the dissection represents a serious risk. The midportion of the recurrent laryngeal nerve and the external branch of the superior laryngeal nerve are encountered in the anterior approach to the lower cervical spine. The(More)
STUDY DESIGN A description of the internal architecture of the sacrum, including its trabecular arrangement, cortical thickness, and overall bone density. OBJECTIVES To determine the strong and weak areas in the sacrum to understand more clearly the sacral structure and its clinical implications. METHODS First, seven cadaveric sacral specimens were(More)
This study evaluated the significance of computed tomographic (CT) measurements of the upper cervical vertebrae and their clinical implications in transarticular C1-C2 screw placement. In the first part of the study, analysis of axial CT scans of the atlas of 46 patients who had a normal C1-C2 region was performed. Measurements included the vertical(More)
This study examined the safe zone for placement of occipital screws without endangering the sinuses. In the first part of the study, 10 cadaveric skulls were exposed. The borders of the confluences and the transverse sinuses were located on the outer table of the occiput. In the second part of the study, six cadaveric skulls were used and screws were placed(More)
Twelve cadaver feet were used for a radiographic assessment of the talonavicular joint. A 4.0- or a 6.5-mm screw was inserted through the posterior tubercle of the talus, directed anteriorly into four quadrants of the talar head. Lateral, dorsoplantar, lateral oblique, and medial oblique radiographic views were obtained for each specimen, to assess the(More)
