Implantable spinal device revision system

Abstract

The invention discloses devices, methods and systems for an implantable revision device useful for altering the biomechanics of an implanted spinal arthroplasty device. The revision device has a first surface adapted to communicate with a natural anatomical surface; and a second surface adapted to engage a portion of the arthroplasty device. The device alters the biomechanics of the implanted spinal arthroplasty device permanently semi-permanently and / or temporarily.

Description

CROSS-REFERENCE [0001] This application is a continuation-in-part of commonly assigned U.S. patent application Ser. No. 11 / 071,541 to Kuiper et al., filed Mar. 2, 2005, and also claims the benefit of U.S. Provisional Patent Application Ser. Nos. 60 / 643,556 to Reiley filed Jan. 13, 2005, and 60 / 602,827 to McLeer filed Aug. 18, 2004, the disclosures of which are both incorporated herein.FIELD OF THE INVENTION [0002] The present invention generally relates to devices and surgical methods for treatment of various spinal pathologies. More specifically, the present invention is directed to configurable and anatomically adaptable implantable devices for use in a spine and surgical procedures for altering the biomechanics of a spine, either temporarily or permanently. The devices alter, replace and / or revise existing anatomy and / or previously implanted devices. BACKGROUND OF THE INVENTION [0003] Back pain, particularly in the small of the back, or lumbosacral region (L4-S1) of the spine (se...

AI Technical Summary

Benefits of technology

[0017] The replacement components or devices of the invention are adapted to the pre-existing implanted arthroplasty devices such that some or all of the existing bone anchors do not need to be removed and / or disturbed to convert the articulating arthroplasty device to a device with controlled, limited and / or no movement.

[0024] Yet another embodiment of the invention provides an implantable device for use with an arthroplasty device, the implantable device comprising a modular stem having a first stem component with a male end, and a second stem component with a female end, wherein the male end is adapted to fit within the female end to prevent rotation and / or relative movement.

[0026] In yet another embodiment of the invention, an implantable device for use with an arthroplasty device comprising a lock adapted to engage a joint of the arthroplasty device to reduce, control, modify and / or prevent articulation of the joint.

Problems solved by technology

Once the initial surgical treatment and implantation has been completed for any of these spinal devices (and their related surgical techniques), additional problems and / or complications, such as additional disc problems, future disc degeneration, stenosis, pseudoarthrosis, junctional failure of the spine, failure of the implant and / or additional nerve compression can occur.

In some cases, problems can occur much later, even years later.
