Orthopedic Fixation Devices and Instruments for Installation Thereof

Abstract

Minimally invasive vertebral stabilization systems may include at least one fastener, at least one coupling element connected to the fastener, and an elongate rod member. The fastener is deliverable to a vertebral body of a patient through an opening. The coupling element has at least one extended tab which defines an open central portion and a central longitudinal axis. The elongate rod member is configured to extend through the open central portion and be secured to the coupling element. The extended tab is configured to be removed from the coupling element once the elongate rod is secured to the coupling element.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation in part of U.S. patent application Ser. No. 14 / 137,157 filed Dec. 20, 2013, the entire disclosure of which is incorporated herein by reference in its entirety for all purposes.FIELD OF THE INVENTION[0002]The present invention relates to orthopedic fixation devices and instruments used to install these devices.BACKGROUND OF THE INVENTION[0003]Many types of spinal irregularities can cause pain, limit range of motion, or injure the nervous system within the spinal column. These irregularities can result from, without limitation, trauma, tumor, disc degeneration, and disease. Often, these irregularities are treated by immobilizing a portion of the spine. This treatment typically involves affixing a plurality of fixation devices to one or more vertebrae and connecting the devices to an elongate rod that generally extends in the direction of the axis of the spine.[0004]Treatment for these spinal irregularities ...

AI Technical Summary

Benefits of technology

[0007]Some embodiments herein are directed to a reduction clip that can include a cannulated body comprising a proximal end and a distal end, the distal end comprising two tips extending therefrom and separated by a longitudinal channel; a rod reduction collar comprising an inner diameter configured to receive at least a portion of the cannulated body; and a reducer configured to fit around at least a portion of the cannulated body, proximal to the rod reduction collar.

Problems solved by technology

Many types of spinal irregularities can cause pain, limit range of motion, or injure the nervous system within the spinal column.

These irregularities can result from, without limitation, trauma, tumor, disc degeneration, and disease.

However, in other situations, such as in a minimally invasive or percutaneous procedure, it may be more difficult for the physician to view and / or maneuver the rod.
