| Popis: | There are several trajectories described for the insertion of screws in the lateral facets of the cervical spine (Magerl, An, Anderson, based on spinous processes,..), they all rely on milimeters and precise angles; but anatomical variety (osteophytes, mass anatomy, spinous process deformities...) might render them not fully reproducible. It is proposed to consider the lateral mass as an slanted cube rotated to present a crest stright posterior, and define a trajectory as close to the 3D diagonal as possible from inferomedial corner at dorsal-medial facet to the anterosuperior cornar of the antero-lateral facet of such a cube.HypothesisThat trajectory is free of biass and represents the longest posible one in a cubic body, so obtaining the strongest anchor possible.Material and Methods10 cervical spines (dry bone) from thew Anatomy Department of Santiago de Compostela University were gathered and 4 different trajectories were developed in each lateral mass from C3 to C6 (both sides) so getting 320 differe... |
