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
Percutanous, minimally invasive implantation of an interspinous
spacer (InSpaceTM, 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.

    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.

    ABSTRACT: Am: The authors present clinical and radiological results of a 3-year follow-up of patients after implantation of interspinous spacers for lateral stenosis. Cohort and methodology: We followed 42 patients with 62 implanted interspinous spacers for a period of three years. The indication for implantation was unilateral or bilateral lateral stenosis with degenerative disc disease. Patients were examined according to an algorithm involving: neurological examination, X-ray - plain and dynamic images, MRI, patients contraindicated for MRI underwent CT examination. Clinical findings were assessed using a VAS score, ODI and Odom criteria. X-rays were performed and the range of motion, distraction in ventral and dorsal areas of the intervertebral disc and foramen intervertebrale and the position of the implant were evaluated. Six months and two years post-surgery, patients underwent postoperative MRI examination and intervertebral foramen distraction in anteroposterior and craniocaudal diameter, and the assessment was compared with preoperative findings. Results: Implantation of interspinous spacers in the lumbar spine in a 3-year follow-up period was followed by the mean improvement of 2.7 points on VAS score, and of 24.5% on ODI. Statistically significant difference in the distraction of the intervertebral foramen in the dorsal part of the intervertebral disc was proven by pre- and post-operative MRI. Conclusion: Implantation of a spacer led to improved ODI and VAS parameters, distraction in the region of the intervertebral foramen, especially in the AP diameter, and in the dorsal part of an intervertebral disc.

    ABSTRACT: Over the last decades, fusion of lumbar spinal motion segments has represented themainstay of treatment of lumbar degenerative conditions which failed to respond adequately to conservative therapy. Increasing demands and expectations from patients as well as the necessity to avoid fusion related negative side effects such as adjacent level disc degeneration, considerable complication and reoperation rates, cranial facet joint violations, pseudarthrosis and others led to the development of motion preserving technologies such as total lumbar disc replacement (TDR). The first and rudimentary attempts to preserve motion of lumbar motion segments can be dated back to the early 1950s. Over the past two to three decades, a variety of new implants with different motion characteristics have been developed and introduced into the market. Despite of the extensive knowledge which has been gained in this field of research, insurers in the United States have refused to reimburse surgeons due to fear of late complications and reoperations as well as unknown secondary costs, which led to a global decline in the numbers of TDR procedures. The current literature review intends to provide a concise summary of the adequate indications for TDR as well as outcome determining factors and delineate the role of TDR in the currently available armamentarium for the treatment of low back pain (LBP) resulting from degenerative disc disease (DDD) without instabilities or deformities.
