Spine stabilization systems and associated devices, assemblies and methods |
摘要 |
A system and method for effecting multi-level spine stabilization is provided. The system includes a plurality of pedicle screws which are joined relative to each other by elongated members, e.g., rods. At least one of the rods includes a dynamic stabilizing member. The pedicle screw junctions are dynamic, i.e., free relative movement of a socket member is permitted relative to a fixed spherical element. Placement of the spherical element may be facilitated using a guidewire system that includes a guidewire and a tapered guide member. A spine stabilization assembly is also provided that includes an attachment member that includes an opening. At least one spherical element that includes a rod-receiving channel is movably mounted within the opening with three degrees of rotational freedom. The spherical element generally defines an elliptical rod-receiving channel that is deformable to a circular opening to firmly engage a rod positioned therein. Multi-level stabilization systems that combine/mix dynamic and non-dynamic stabilization modalities are also provided. The multi-level spine stabilization system offers efficacious clinical results at least in part due to the inclusion of dynamic stabilizing member(s).
