SOFT STABILIZATION ASSEMBLIES WITH OFF-SET CONNECTOR

摘要

A spinal longitudinal connecting member includes a soft stabilization assembly segment having a tensioned cord and a hard rod segment. A connector in fixed engagement with the hard rod also captures the tensioned cord of the soft segment, the connector being in fixed or sliding relation with the tensioned cord. The connector places the soft assembly segment in lateral or off-set and staggered relation to the hard rod segment. The connector may be integral to a bone anchor.

主权项

1. A longitudinal connecting member assembly having first and second bone anchors spanning between first and second vertebrae, the assembly comprising:
a) a soft portion having a cord in continuous tension, the cord being in slideable relation with the first bone anchor, wherein the anchor is positioned between an end blocker-bumper and a spacer; b) a hard portion being in fixed relation with the second bone anchor; c) a connecting structure in fixed relation with the hard portion and in one of a fixed and a sliding relation with the cord, the connecting structure positioning the soft portion in a lateral and staggered relation with the hard portion; d) a hard end structure fixed to the cord; and e) an elastic bumper and a spacer both being in slidable relation with the cord, the elastic bumper positioned between the end structure and the first bone anchor, the first bone anchor being positioned between the elastic bumper and the spacer.
