Summary

To evaluate clinical, radiologic and patient-reported outcomes who have been treated 1 or 2 levels with the coflex® Interlaminar Technology or decompression with or without fusion.

Detailed description

The coflex® Interlaminar Technology - manufactured by Paradigm Spine - is intended for use as a permanent implant between the lamina of 1 or 2 lumbar motion segments in the treatment of moderate to severe lumbar spinal stenosis. The device is specifically designed to provide stabilization without fusion in cases of stenosis with or without facet joint hypertrophy, subarticular recess stenosis or foraminal stenosis. It is restricted for use to one or two levels in the region of L1 - L5. The height of the neuroforamen is maintained and the facet joints will be relieved. By this a further destruction is prevented. Unlike conventional stabilization methods as for example spinal fusion, the function of the segment will be maintained and adjacent structures will be effectively protected. Possible risks, which could occur after implantation of the coflex® Interlaminar Technology are breakage of the implant, displacement of the implant, pain which is caused by the implant, infections, bleedings and hematoma. The benefit of the study lies in the fact that first-time retrospective data is raised for potential improvement regarding therapy of lumbar back pain with the treatment of the lumbar spinal stenosis, which, in the future, can lead to an improvement of the therapy. In this study, Paradigm Spine will retrospectively collect clinical and radiographic data for patients treated with the coflex® Interlaminar Technology during normal conditions of use. This data will provide evidence to support publications and marketing.
