There were no other complications or reoperation in either group.

It has also been argued that using pedicle-based dynamic devices can promote better fusion because of micromovements across endplates, and can protect from implant failure because of better load sharing through the implant. Table 2 Clinical outcomes of the two groups. The intended use for each level is as specified for each system. Results Mean patient age, gender, and follow-up time were similar between groups.

This device is only intended to be used when fusion with bone graft is being performed at all instrumented levels. The cord engages and acts as a tension band Overall flexion is limited. When 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 and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: Spinal fusion results in increased stress in the adjacent segments and subsequent hypermobility, which may leads to adjacent segment disease[ 1011 ].

Non-fusion system for the spine The Dynesys System from Zimmer is an alternative method of treatment zimmfr degenerative diseases of the lumbar spine. Zimmed load-bearing capacity of the implant can be compromised by notching, scratching, or striking. This retrospective study included 46 consecutive patients who underwent Dynesys stabilization for lumbar degenerative disc disease from July to March All patients were followed-up for a minimum of 48 months.

Schaeren S, Broger I, Jeanneret B Minimum four-year follow-up of spinal stenosis with degenerative spondylolisthesis treated with decompression and dynamic stabilization. These systems should only be used with instrumentation specifically designed for each system.

The device has not been evaluated for safety and compatibility in the MR environment. The study protocol was approved by the Institutional Review Board of our hospital. 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.

The intended use for each level is as specified for each system. The intended use for each level is as specified for each system. The Dynesys Dynamic Stabilization System was designed as a more physiologic system of spine stabilization. Stabilization with the Dynesys system was performed as an open procedure with a midline skin incision.

Moreover, increased range of movement ROM at adjacent segments after spinal fusion may increase the risk for adjacent segment degeneration ASD [ 1 ]. This problem can be resolved by the development of dynamic zimmeg techniques. The following adverse effects have been reported: Discopathy hypomobile; degenerative retrolisthesis up to grade I Discopathy hypermobile; degenerative antelisthesis up to grade I Degenerative pseudo-spondylolisthesis up to grade I Mono- or multisegmental lumbar stenosis with or without olisthesis.

Remove any protective devices prior to the final implantation i. Implants must not be machined or altered in any way, unless this is expressly envisaged in the design and in the surgical technique.

The system is intended to be used without bone graft for the following indications.

Radiographic outcomes included segmental ROM and the disc height of the stabilized segments and upper adjacent segments. The system uses three proprietary components to stabilize the spine: These patients should be informed of this increased risk and counselled to discontinue tobacco use prior to and immediately after surgery.

Contraindications of the Dynesys Spinal System are similar to other commercially available posterior spinal fixation systems. The objective of this study is to compare the clinical and radiographic outcomes of Dynesys and PLIF for lumbar degenerative disease.

A senior surgeon resolved disagreements in measurements. Do not use any component if damage is found or caused during setup or insertion.

For the best experience on Zimmer websites please upgrade to the latest version of Internet ExplorerChromeor Firefox. Dynamic stabilization is a surgical technique designed to allow for some movement of the spine, while maintaining enough stability to prevent too much movement. The incidence of complications was comparable between groups. Proper patient selection will greatly affect the results. Primary discopathy spondylosis and spondylarthrosis in combination with: The patient must be told that implants can affect the results of computer tomography CT or magnetic resonance imaging MRI scans.

This is due to dyneshs technically demanding procedure presenting a risk of serious injury to the patient. J Spinal Disord Tech Fifty patients who underwent PLIF with the same disease at the same stage were retrospectively matched as a control group.
