Problems solved by technology

However, the problem is that this technique may perturb some previously asymptomatic levels of the spine and thus cause pain that was not previously present.
Options for adding and replacing hardware are time-consuming, especially if the surgeon is unfamiliar with the patient's existing hardware

Embodiment Construction

[0042] The specific terminology used in the following description is for convenience only and should not be considered limiting in any way. For example, bone fixation assembly 20 includes one or more bone fixation elements 22, Figure 1A Shown in is four bone fixation elements 22A-D. Such as Figure 1B As shown in , each bone fixation element 22 extends vertically in an axial direction A and generally horizontally in a radial direction R, which extends perpendicular to the axial direction A. Thus, the radial direction R comprises a longitudinal direction L as well as a transverse direction LA extending perpendicularly to this longitudinal direction L. It should be appreciated that the directional terms "longitudinal" and "transverse" may likewise be used for a horizontally extending bone fixation assembly 20, while the directional term "transverse to" may refer to a vertical direction. Bone fixation element 22 defines an upper end 21 and a lower end 23 such that the directio...

Abstract

A revision connector is configured to couple a new spine fixation rod to a previously implanted spine fixation rod that is secured to a plurality of vertebrae. The new spine fixation rod can be implanted and secured to vertebrae that are caudal and / or cranial with respect to the previously secured vertebrae.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 169,336, filed April 15, 2009, the contents of which are incorporated herein by reference as if in their entirety explained in this article. technical field [0003] The present invention relates generally to orthopedics, and more particularly to implants and methods for modifying an existing posterior pedicle screw assembly to an additional level. Background technique [0004] Existing options for modifying and / or extending posterior pedicle screw and rod structures in a patient are limited. Patients who have had previous spinal surgery often develop adjacent vertebral level disorders, which often cause pain and require additional surgery. Such additional spinal surgery typically entails extending existing hardware structures by one or more additional vertebral levels. In this case, the surgeon must decide whether he can 1) extend the...
