- To focus on anatomy and bio-mechanics of the interapophyseal joints,
their innervation and potential involvment as one of the many - and frequently misdiagnosed - causes of back pain. - To expose how facet syndrome can be managed and treated by the Interventional Radiologist,
showing the state-of-the-art of the available techniques for percutaneous treatment and technical aspects of their execution.
Background Facet syndrome has high prevalence in elderly populations,
because of their frequent arthritic degeneration of the interapophyseal joints in conditions of chronic overload,
sometimes associated with repeated microtrauma.
Less frequently facet syndrome is associated to synovitis with fluid distension of the articular capsule (which might be caused by microtrauma,
inflammatory aspecific reactions or their rheumatological involvement),
entrapment of meniscoid articular structures,...
