PRIMARY-TREATMENT OF UNSTABLE JEFFERSONS FRACTURES

The Magerl transfacet screw technique is a method of fixation for unst able burst fractures of the atlas (Jefferson's fracture) that preclude s the use of a halo brace or stabilization from the occiput to C-2. Tw o cases are presented utilizing this mode of treatment to obtain solid arthrodesis and maintain intact motion at occipital cervical junction . No increased displacement of the fractured ring of C-1 occurred with the screw insertion. Thus, primary C-1-C-2 transfacet screw fixation is a useful alternative treatment for unstable Jefferson's fractures.
