The Dynesys Dynamic Stabilization System was designed as a more physiologic system of spine stabilization. The safety and effectiveness of this device has not been established for the intended use of spinal stabilization without fusion. This device is only intended to be used when fusion with bone graft is being performed at all instrumented levels.
The Dynesys Dynamic Stabilization System combines the surgical approach of traditional spinal fusion with the philosophy of dynamic stabilization, using flexible materials to stabilize the spine while preserving anatomical structures.
The system uses three proprietary components to stabilize the spine as an adjunct to fusion. Dynesy used as a pedicle screw fixation system in skeletally mature patients, the Dynesys Spinal System is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion in the treatment of the following acute izmmer chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: In addition, when used as a pedicle screw fixation system, the Dynesys Spinal System is indicated for use in patients:.
The intended use for each level is as specified for each system. Contraindications of the Dynesys Spinal System are similar to other commercially available posterior spinal fixation systems. Contraindications include but are not limited to the following:.
The safety and effectiveness of the Dynesys Spinal System and the Zimmer DTO Dynesyd have not been established for spinal indications beyond those stated in the Indications section.
This is due to the technically demanding procedure presenting a risk of serious injury to the patient.
These systems should only be used with instrumentation specifically designed for each system. Refer to the respective surgical techniques to determine which instruments should be used for each step of the surgical procedure.
A successful result is not always achieved in every surgical case. The patients should be made aware that a successful result, as defined by reduced pain, increased function and the establishment of solid fusion, is not always achieved in every surgical case.
Proper patient selection will greatly affect the results. Patients who smoke have been shown to have an increased incidence of non-union. These patients should be informed of this increased risk and counselled to discontinue tobacco use prior to zimmerr immediately after surgery. The use of autogenous bone graft has been shown to provide superior results compared to the use of allograft bone graft material.

In addition to the above specified warnings and precautions, general surgical risks should be explained to the patient prior to surgery. Prior to surgery, patients should be made aware of the following possible adverse effects in addition to the potential for additional surgery to correct these effects:. Zimmer Biomet Spine, Inc. Holds the segments in a more natural anatomic position using non-rigid materials Preserves natural anatomical structures as much as possible Constrains spinal motion “internal splint” Zimmer Biomet Spine offers three dynamic stabilization options: Dynesys Top-Loading Spinal System Offers a top-loading, cannulated screw option Standard and HA coated screws available in all sizes Allows for a less invasive paraspinal approach Uses unique instrumentation for direct implantation of the cord and spacer.

Biomechanics of the Dynesys System The Dynesys Dynamic Stabilization System combines the surgical approach of traditional spinal fusion with the philosophy of dynamic stabilization, using flexible materials to stabilize the spine while preserving anatomical structures.
Titanium screws anchor the system to the spine Polycarbonate urethane spacers limit spinal extension Polymer cord acts as a tension band to limit spinal flexion. The system is placed under tension creating a dynamic interaction between the components.
When the patient bends forward: The cord engages and acts as a tension band Overall flexion is limited. Flexion When the patient bends backward: The screw heads interact with the spacer The spacer resists the compressive load Overall extension is limited.
In addition, when used as a pedicle screw fixation system, the Dynesys Spinal System is indicated for use in patients: Who are receiving fusions with autogenous graft only; Who are having the device fixed or attached to the lumbar or sacral spine; Who are having the device removed after the development of a solid fusion mass. Contraindications include but are not limited to the following: Complications and Possible Adverse Events.
