Conditions

Intervertebral Disc Degeneration, Lumbar Spinal Stenosis

Brief summary

The purpose of this study is to determine the effectiveness of minimally invasive surgical technique over the traditional open surgical procedure in patients with degenerative lumbar stenosis

Interventions

DEVICELumbar fusion

Patients will receive a single level instrumented fusion using a minimally invasive or open traditional surgical procedure with a posterior fixation. For the use of a posterior fixation system, the CD Horizon® Spinal System, is mandatory in this study and will be either minimally invasive or open.

Inclusion criteria

* Age 18 to 75 years; * Patient has single level degenerative lumbar spinal stenosis and an indication for a single level instrumented lumbar fusion for the treatment; * Symptoms persisting for at least three months prior to surgery; * Given written Informed Consent; * Able and agree to fully comply with the clinical protocol and willing to adhere to follow-up schedule and requirements.

Exclusion criteria

* Prior lumbar spinal fusion at any level; * Other non-degenerative spinal conditions (e.g. infectious, traumatic, metabolic, inflammatory, neoplastic, structural or other pathology) that may have an impact on subject safety, wellbeing or the intent and conduct of the study; * Any condition that cannot be treated with mini-invasive unilateral decompression and fusion; * History or presence of any other major neurological disease or condition that may interfere with the study assessments (e.g. significant peripheral neuropathy, multiply sclerosis); * Previous enrollment in this study, current enrollment or plans to be enrolled in another study (in parallel to this study).
