ABSTRACT:
Transverse connector (10) bridges rod connector assemblies (40 and 70), and includes an elongate body (12) along longitudinal axis (L). A first portion (20) is formed at a first end (22) of elongate body (12), and has an interlocking surface (26) configured to engage rod connector assembly 40 in variable rotational positions which need not be perpendicular to rod (R1). A second portion (30) is formed at an opposite second end (32) of elongate body (12) and has interlocking surface (36) configured to engage rod connector assembly (70) in variable linear positions. As a result, transverse connector (10) accommodates variable spacing of rods (R1 and R2), and variable positioning of rod connector assemblies (40 and 70) thereon. Rod connector assemblies (40 and 70) include bone screw plates (50 and 80), respectively, connected thereto. A spinal fixation system results which permits connection of a transverse connector (10) at the same site along a rod as a vertebral fixation element.
