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.
Central, lateral and foraminal dynamic lumbar spinal
Discogenic and arthrogenic (facet osteoarthritis) low back
Symptomatic, segmental hyperlordosis.
Disc degeneration with dynamic (reducible) retrolisthesis.
Interspinous pain (‚Kissing-Spines’).
Structural spinal stenosis.
Spondylolisthesis (degenerative and/or isthmic).
Previous posterior operation in index segment.
Surgical Technique
Percutanous, minimally invasive implantation of an interspinous
spacer (InSpaceTM, Synthes, Oberdorf, Switzerland).
Postoperative Management
Early unrestricted mobilization.
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.

    ABSTRACT: Total lumbar disk replacement has become a routine procedure in many countries. However, discussions regarding its use are ongoing. Issues focus on patient selection, technical limitations, and avoidance or management of complications or long-term outcomes. A review of the development of this technology, since the development of the first successful implantation of a total lumbar disk prosthesis in 1984, shows an amazing analogy to the history of total hip replacement. This article is a one-to-one comparison of the evolution of total hip and total lumbar disk replacement from "skunk works" to scientific evidence.
