Quote:Chronic benign "back pain ", with or without sciatica, is a descriptive diagnosis hiding the mechanisms leading to this symptom. The literature still refers to it as a "non-specific" disease. Not surprisingly, both conservative and invasive treatments are inconsistent and highly subjective. The book aims to highlight the main pathogenetic mechanisms leading to pain based on a thorough analysis of the lumbar spine anatomy and mechanics (including its vascular content) and a selection of published evidence converging towards an original integrated model. The result is a downgrading of back pain from a "non-specific" disease to a symptom and clarifying the underlying causes.
