Problems solved by technology

These disks may herniate or rupture from trauma or strain, especially if degenerative changes have occurred in the disk.
A herniated intervertebral disk, also known as a slipped or ruptured disk, is a condition in which part or all of the soft, gelatinous nucleus pulposus in the central portion of an intervertebral disk is forced through a weakened part of the annulus fibrosis, resulting in back pain and nerve root irritation.
When lumbar disk herniation occurs, nerve roots, the large nerves that branch out from the spinal cord, may become compressed resulting in neurological symptoms such as pain or weakness in the back and lower extremities.
In spite of the fact that the procedure has been done for many years, few studies have been conducted to determine its real effectiveness.
Scar tissue may develop after discectomy, which, in some cases, can cause continued pain.

Embodiment Construction

[0020] The present invention relates to a method of spinal fixation involving application of a liquid medium which cures, hardens, polymerizes or otherwise serves to bind adjacent vertebrae together. The fixation which results from this binding may be temporary or essentially permanent in duration, and may be used to treat inflammation, disk herniation, and / or fracture or instability in the spine.

[0021] The terms “medium” and “media” as used herein, refer to the liquid material used according to preferred embodiments herein to join one or more adjacent vertebrae. Preferred media comprise an adhesive, which is used in a broad sense to include single component or multiple component materials, curable compositions, polymerizable compositions, cements, as well as other types of materials or compounds, presently known or later-developed, which may be used to join, bond or adhere surfaces or materials together. Suitable adhesives include both biological and non-biological adhesives. The ...

Abstract

Disclosed are methods of spinal fixation involving application of a liquid medium which cures, hardens, polymerizes or otherwise serves to bind adjacent vertebrae together. The fixation which results from this binding may be temporary or essentially permanent in duration, and may be used to treat conditions or disease of the spine, such as inflammation, instability or fracture. In a preferred embodiment, the liquid medium comprises a low viscosity cyanoacrylate-based adhesive.

Description

RELATED APPLICATION INFORMATION [0001] This application is a Continuation of U.S. application Ser. No. 10 / 827,101 filed on Apr. 19, 2004, now U.S. Pat. No. ______, which is a Continuation of U.S. application Ser. No. 10 / 041,652 filed Dec. 28, 2001, now U.S. Pat. No. 6,723,095, both the disclosures of which are incorporated by reference in their entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a method of spinal fixation involving application of a liquid medium which cures, hardens, polymerizes or otherwise serves to bind adjacent vertebrae together. The fixation which results from this binding may be temporary or essentially permanent in duration. [0004] 2. Description of the Related Art [0005] The spinal vertebrae are separated by cartilage disks, filled with a gelatinous substance, that provide cushioning to the spinal column. These disks may herniate or rupture from trauma or strain, especially if degenerative changes h...
