Behandlungsergebnisse bei Patienten mit lumbaler Spinalstenose nach dynamischer Stabilisierung mittels interspinöser Implantate

Yasin Ajez, Pfeiffer, M. (Prof. Dr. Med.)
A narrowed spinal canal is called lumbar spinal stenosis. Often this painful disorder is caused by degenerative changes of the spine. Primary a conservative, stabilizing therapy is attempted. If the symptoms worsen or a significant deterioration of the quality of life occurs the conservative therapy failured and an operative rehabilitation is indicated. Due to demographic changes, most of the patients undergoing spine surgery are elderly. The crucial step of this operation is to decompress the

However, in this case there is the risk of instability, which in turn increases the strain in the corresponding segment, and thus promotes its degenerative changes. To avoid this problem, a fusion of this segment can be performed. This fusion is problematic, as it completely eliminates the flexibility in the corresponding region and increases the degenerative changes in the adjacent segments. A solution to this problem may be segmental distraction and decompression via dynamic stabilization of the spine. Here the vertebral bodies are not fused and allow some residual motion. To enable this, implants such as Wallis, In-SWing, Le U, DIAM, and X-Stop can be used. Aim of the study: Interspinous implants (Wallis, X-Stop, Le U, InSWing) are and were often applied in surgery of the lumbar spine. Despite this, there are only very few clinicalradiological studies published todate. From March 2008 to July 2009, 33 patients being operatively supplied with aforementioned lumbar interspinous implants in the Helios Rosmann Hospital Breisach, Germany, due to lower back pain and / or sciatica, a part of them with significant palsy or sensory disturbances, were included in the study. Aim of this retrospective study was mainly to investigate the cli [...]
