The system is constructed of flexible materials that stabilize the affected vertebral segments. The Dynesys system consists of external spacers made of surgical polyurethane tubing surrounding a polyethylene cord. The system is designed to permit careful controlled bending, straightening and twisting movement in the affected joints.

This unique system has several potential advantages over current fusion techniques. The most important is the preservation of the intervertebral discs and anatomy of the affected vertebrae. Also, the Dynesys system is installed Posteriorly.

The procedure should also reduce the number of days patients need for recovery. Scheduling Detailed Phone Directory. Farrell, MD John H. Feibel, MD Todd A. Michael, MD J.

Dynesys The Dynesys system uses flexible materials to stabilize the affected lumbar region while preserving the natural anatomy of the spine. The procedure allows some motion in the spine and is easy to implant using a familiar surgical approach.

Long-Term Outcome of Dynesys Dynamic Stabilization for Lumbar Spinal Stenosis

Language: English Chinese. Many clinical studies over the past decade have indicated positive outcomes for patients treated with Dynesys dynamic stabilization for lumbar degenerative disease. However, long-term outcomes of Dynesys for lumbar spinal stenosis are rarely reported. The aim of this study was to analyze the long-term clinical and radiologic outcomes for patients with lumbar spinal stenosis treated with Dynesys stabilization. Thirty-eight patients with lumbar spinal stenosis were treated with Dynesys stabilization from July to March The minimal duration of follow-up was 72 months. The patients were divided into stenosis and spondylolisthesis groups according to degenerative spondylolisthesis.

The PET cord resists tensile forces and provides resistance to spine flexion similar in concept to the Graf system. However, the Dynesys PCU spacer resists compression during extension and thereby maintains foraminal height and decreases load to the posterior annulus. The Dynesys system is FDA approved as an adjunct device for spinal fusion, however, through controlled motion and indirect decompression, the Dynesys system attempts to decrease discogenic low back pain while minimizing the risk for adjacent segment degeneration. The Dynesys Dynamic Stabilization System was designed as a more physiologic system of spine stabilization. The system is intended to be used without bone graft for the following indications.
