Lumbar Spine Surgery Medial Branch Nerve Block Injection demonstrative evidence 3D animations. This movie illustrates the technique for performing a lumbar medial branch nerve block. This shows positioning, preparation, local anesthetic injection, needle introduction over the medial branch nerve, contrast injection to check the needle tip position, steroid / anesthetic injection. The facet joint connects the inferior articular process of the vertebra above. Adjacent vertebra are connected by a right and left facet joint. They are sometimes referred to as zygopophysial joints or z-joints. A facet joint can be a source of back pain. The medial branch nerve initially transmits this pain message on its way to the brain and a demonstrative evidence 3D animation.
A medial branch block injection is used to inject medication around this nerve to prevent it transmitting the pain message to the brain. Lumbar Spine Surgery Medial Branch Nerve Block Injection demonstrative evidence 3D animations.
