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.

The intent of the Dynesys system is to provide spine surgeons with an alternative to the rigid fixation provided by today’s systems for spinal fusion. 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 dynamic push/pull relationship between the spacers and the cord stabilizes the affected vertebrae. 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.
