Abstract

The present invention discloses an anterior transpedicular bone fixation device (100) including a first plate (105) having at least one fastener hole (120a) configured to receive at least a portion of a first bone fastener and a first rotatable eccentric member (112). The first eccentric member has a first aperture (106) for receiving at least a portion of a central fastener (108). A second plate has at least one fastener hole (120c) configured to receive at least a portion of a second bone fastener and a second rotatable eccentric member (114) with a second aperture (107) for receiving at least a portion of the central fastener, wherein the first and second rotatable eccentric members enable the first plate and second plate to translation with respect to one another. The orientation of the first plate with respect to the second plate can be fixed by advancing the central fastener through the apertures.

[0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 098036, filed September 18, 2008, entitled "ANTERIOR TRANSPEDICULAR SCREW-AND-PLATE SYSTEM," which The contents of are incorporated by reference herein in their entirety. Background technique

[0003] Multilevel cervical procedures place relatively large loads on the anterior cervical screw and plate system, especially in cases of severe three-column lower cervical spine injuries and in multilevel plated reconstructions of osteoporotic bone. Therefore, supplementary posterior instrumentation is recommended to increase primary structural stiffness and limit possible damage to the screw and plate system. The increased number of successful posterior cervical pedicle screw fixations will enable more stable fixation, however, most cervical pathology is anterior and is preferably addressed by an anterior approach.
