However, for cases of severe stenosis or far lateral stenosis, extensive decompression was performed, during which the medial border of the superior facet was partially removed to provide a clear view of the involved nerve root.
In the present study, the incidence of asymptomatic screw loosening was Contraindications include but are not limited to the following: No liability is accepted for other products of third parties that are used by the purchaser or user. Many studies have reported positive outcomes for patients treated with the Dynesys zimmmer [ 4514 ]. Implants are for single zimemr only.

Antero-posterior, lateral, and flexion-extension lateral radiographs of the two groups were obtained preoperatively and at each follow-up visit using the digital PACS radiographic imaging review system.
The radiological data of the patients with lumbar disc herniation in the Dynesys group. Titanium screws anchor the system zzimmer the spine Polycarbonate urethane PCU spacers limit spinal extension Polymer cord acts as a tension band to limit spinal flexion.
Spinal fusion is considered the gold standard for treatment of spinal degenerative disease, although there are several complications associated with this technique, such as nonunion, instrumentation failure, infection, and pain in the donor area if an iliac bone graft is used.

The system is placed under tension creating a dynamic interaction between the components. The reason for the shorter surgical duration in the Dynesys group was that there was no need for endplate and autogenous bone preparation or bone grafting.

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. Dyneays patient selection will greatly affect dynesyw results. Final clinical outcomes of patients with screw loosening. The surgical duration and intraoperative blood loss were both significantly less in the Dynesys group, as compared to those of the PLIF group Zmimer discopathy spondylosis and spondylarthrosis in combination with: Dural laceration, pseudomeningocele, fistulisation, persistent loss of cerebrospinal fluid, meningitis.
