Zimmer Dynesys (Implant ) –

Spinal fusion results in increased stress in the adjacent segments and subsequent hypermobility, which may leads to adjacent segment disease[ 1011 ]. Legaye J [ Unfavorable influence of the dynamic neutralization system on sagittal balance of the spine ].

Flexion When the patient bends backward: Complications There were no significant differences in the incidence of asymptomatic screw loosening between the Dynesys and PLIF groups 6 vs. The ROM of stabilized segments in the Dynesys group decreased from 7.

Discussion The result of this study indicated that after a minimum follow-up of 4 years, both Dynesys and PLIF improved clinical outcomes for lumbar zmimer disease. Nonetheless, screw loosening has no adverse effect on clinical improvement.

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: Adjacent segment disease after spinal fusion has drawn considerable attention over the past two decades.

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. Dural laceration, fynesys, fistulisation, persistent loss of cerebrospinal fluid, meningitis. Fracture, resorption, damage or penetration of a spinal bone. The fusion rate was Materials and Methods Patient selection This retrospective study included 46 consecutive patients who underwent Dynesys stabilization for lumbar degenerative disc disease from July to March Clin Neurol Neurosurg Zimmer Biomet serves healthcare professionals and their patients globally.

Tsutsumimoto T, Shimogata M, Ohta H, Misawa H Mini-open versus conventional open posterior lumbar interbody fusion for the treatment of lumbar degenerative spondylolisthesis: Holds the segments in a more natural anatomic dyneeys using non-rigid materials Preserves natural anatomical structures as much as possible Constrains spinal motion “internal splint” Zimmer Spine offers three dynamic stabilization options: We also divided each group into two subgroups single and multiple level groups for subgroup analysis of segmental ROM.

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

Because ASD frequently occurred superior to the operated segment, we only evaluated the radiographic outcomes of the upper adjacent segment [ 8 ].

The system is placed under tension creating a dynamic interaction between the components. The incidence of other complications, including dural tear and superficial wound dtnesys, was similar between groups.

Primary discopathy spondylosis and spondylarthrosis in combination with: The segmental ROM was calculated as the difference between the segmental angulations in flexion and extension.

In addition to the above specified warnings and precautions, general surgical risks should be explained to the patient prior to surgery. All patients fynesys followed-up for a minimum of 48 months.

The ROM of the upper segments increased significantly in both groups at the final follow-up, although to a higher degree in the PLIF group. Cookies Preferences The cookie settings on zimmee website are currently set to allow certain types of cookies. Table 1 Patient demographic and baseline data.

Provides a controlled range of motion in flexion and extension 3. Clinical and radiographic evaluations All patients received postoperative zimmdr and radiographic examinations at 3 months, 1 year, and then every year afterward.

For product information, including indications, contraindications, warnings, precautions, potential adverse effects and patient counseling information, see the package insert and information on this website. All patients experienced failure of conservative treatment for at least 3 months before they were considered for surgical intervention.

Provides a controlled range of motion in flexion and extension. Eur Spine J The inclusion criteria and indications were: The segmental angulations were measured in the lateral standing lumbar radiography between the inferior surface of the upper vertebra and the superior surface of the lower vertebra.

Bone fractures following overloading, incorrect choice of the implant size or weakened bone substance. We also evaluated the occurrence of dynnesys and symptomatic adjacent segment degeneration ASD.
