Abstract

SURGICAL GOAL: Surgical treatment of dynamic lumbar spinal stenosis and discogenic/arthrogenic low back pain with a new percutaneous interspinous spacer as a therapeutic alternative to more invasive standard procedures.

Indications: Central, lateral and foraminal dynamic lumbar spinal stenosis. Discogenic and arthrogenic (facet osteoarthritis) low back pain. Symptomatic, segmental hyperlordosis. Disc degeneration with dynamic (reducible) retrolisthesis. Interspinous pain ('Kissing-Spines').

Contraindications: Osteoporosis. Conus-/Cauda-syndrome. Structural spinal stenosis. Spondylolisthesis (degenerative and/or isthmic). Deformities. Previous posterior operation in index segment.

Surgical technique: Percutaneous, minimally invasive implantation of an interspinous spacer (InSpace ™, Synthes, Oberdorf, Switzerland).

Postoperative management: Early unrestricted mobilization.

Results: Good early results (after 2 year follow-up) in 42 patients with 76% subjective patient satisfaction rate. No approach related complications. Avoidance of the more invasive alternative procedure (decompression, fusion, total disc replacement) in 76.2% of the patients.
