The theoretical pathology of acute locked back. A basis for manipulative therapy DIE PATHOPHYSIOLOGIE DER AKUTEN LWS-BLOCKIERUNG. EINE BASIS ZUR MANIPULATIVEN THEORIE

As an explanation for the pathological basis for acute locked back, meniscus entrapment is a concept that is inconsistent with both the anatomy of zygapophysial menisci and the clinical features of acute locked back. Two alternative explanations that better fit the clinical features are postulated: meniscus extrapment and intradiscal nuclear displacement, both of which are amenable to manipulative therapy.
