The innervation of L5-S1 element joint differs from the other back joints considering that it is innervated by the medial branch of L4 and the dorsal ramus of L5. The course of the L5 median branch is rather modified since the transverse procedure is changed by the ala of the sacrum.

Rizolisis Cervical

FIGURE 3-1. Posterior view of the back spinal column showing the anatomy and innervation of the element joints. FIGURE 3-2. Oblique view of the lumbar spine showing the anatomy and innervation of the element joints. Medical Presentation Disorders of the element joints present as persistent neck pain and/or persistent pain in the back.

The C2-3 and C5-6 element joints are commonly impacted sectors in cases of cervical facet-mediated discomfort. Lumbar element joint4 involvement presents as axial back pain or pain radiating into the butts up to the posterior thigh, with increased discomfort while standing or bending backwards. L4-L5 and L5-S1 segments are frequently credited to be the source of the discomfort.

5 All the standards and commissioned position papers endorsed by major spine and interventional discomfort societies recommend using double-level blocks to screen patients for facet joint denervation. On the other hand, Cohen et al.,5 in a multicenter analysis, concluded that the degree of discomfort relief gotten after diagnostic screening blocks does not associate with zygapophyseal joint denervation results.

Diagnostic blocks of an element or zygapophyseal joint can be carried out by anesthetizing the joint with injections of local anesthetic/steroid intra-articularly or peri-articularly on the median branches of the dorsal rami that innervate the joint, to assess whether the facet joint is the source of pain. Once the facet joint has been shown to be the source of pain, various methods are offered for healing aspect denervation that include radiofrequency denervation (non-pulsed, pulsed, or cooled), chemical element neurolysis, laser aspect thermal ablation (also known as laser element neurolysis), and cryodenervation.

In addition, care must be taken so that injection does not burst or overly distend the joint. The medial branch block, in contrast, needs anesthetizing both median branches that innervate the target joint. Substantial leakage of intra-articular injected fluid into the epidural space and spill over to the nerve roots have been explained, which reduces the diagnostic precision of aspect blocks.

Finally, intra-articular blocks are appropriate if intra-articular therapy is proposed; but if radiofrequency therapy is proposed, MBBs end up being the diagnostic procedure of option. The diagnostic and restorative outcomes between the 2 techniques (i. e., intra-articular vs. MBB) have been found to be comparable in methodical reviews; both are related to substantial rates of false-positives and negatives.

Radiculalgia

Many private investigators believe that a favorable reaction with at least 50% enhancement in clinical signs need to be recorded compared to standard. Other private investigators prefer a reaction of a minimum of 80% improvement. This procedure is done as a daycare surgery treatment. The patient is positioned prone on the fluoroscopy table, with a pillow under the abdominal area to decrease the lumbar lordosis.

This renders the beam parallel to the posterolateral part of the joint, which is accessible for direct leak. A 22-gauge spinal needle (3 or 5 inches) is placed on the skin so that the suggestion is forecasted over the inferior part of the joint. Using the needle pointer as a marker, 510 m, L of 1% lignocaine is injected into the skin and subcutaneous tissue.
