Anterior Transpedicular Fixation System And Method For Maintaining A Vertebral Column
The Present Invention Relates To An Internal Anterior Transpedicular Fixation System And A Method For Rigidly Fixing The Spine Anteriorly At The Level Above And Below A Thoracolumbar Burst Fracture Or Tumor. The Internal Anterior Transpedicular Fixation System Has A Support Member Defining A Plurality Of Engaging Portions Thereon. At Least Two Of The Engaging Portions Are Spaced Longitudinally From Each Other And Adapted To Span At Least One Verteba. At Least Two Of The Engaging Portions Are Spaced Laterally From Each Other And Adapted To Span A Lateral Distance Of The Verteba. A Plurality Of Fixation Elements Are Provided To Mount The Engaging Portions Onto The Verteba. Thereby, The Support Member Is Restrained From Rotational Or Translational Movement Relative To The Verteba.
