Zusammenfassung

Der lumbalen Spinalkanalstenose kommt aufgrund der sich wandelnden Bevölkerungsstruktur und des wachsenden Anspruchs älterer Patienten an die Lebensqualität eine immer größere Bedeutung zu. Die aktuellen Behandlungsempfehlungen basieren weniger auf nachgewiesener Evidenz als auf klinischer Erfahrung, Expertenmeinungen und Einzelstudien. Das radiologische Ausmaß einer Stenose korreliert nicht mit der klinischen Situation der Patienten. Es stellt nicht das Kriterium zur Operation dar, sondern die typische Anamnese und Claudicatio spinalis. Symptomatische Patienten mit leichten bis mittelschweren Beschwerden sollten multimodal konservativ behandelt werden. Epidurale Infiltrationen und entlordosierende Maßnahmen sind sinnvoll, ggf. auch eine medikamentöse Therapie. Bei hochgradigen symptomatischen Stenosen sollte nach erfolglosem konservativem Therapieversuch über 3 Monate eine operative Therapie erfolgen. Hochgradige Paresen oder Kaudasyndrom sind absolute Operationsindikationen. Ziel ist eine optimale Dekompression bei größtmöglichem Erhalt oder Wiederherstellung der Segmentstabilität. Eine Laminektomie ist nicht erforderlich. Bei begleitender degenerativer Spondylolisthese Meyerding Grad I–II oder Hypermobilität in den Funktionsaufnahmen ist zusätzlich zur Dekompression abhängig vom Alter und Aktivitätsgrad des Patienten eine Fusion oder dynamische Stabilisierung anzustreben.

Abstract

Lumbal spinal stenosis is gaining more and more clinical relevance because of changing population structure and increasing demand on lifequality in the elderly. Current treatment recommendations are based on clinical experience, expert opinions and single studies rather than on proven evidence. The radiologic degree of stenosis does not correlate with the patients’ clinical situation. It is not the main factor indicating surgery but rather the typical history and spinal claudication. Symptomatic patients with light to moderate complaints should undergo multimodal conservative treatment. Epidural injections, delordosating physiotherapy and medication are useful. In patients with severe symptomatic stenosis surgery is indicated after a conservative treatment of 3 months. Relevant pareses or a cauda equina syndrome are absolute indications for surgery. The general aim is to decompress sufficiently while maintaining or restoring segmental stability. A laminectomy is not necessarily required. In patients with accompanying degenerative Meyerding grade I–II spondylolisthesis or instability in functional radiographs, fusion or dynamic stabilisation are recommended in addition to decompression, depending on the patient’s age and activity level.
