Facet Joint Injection

What is a facet joint injection?

Facet Joint Injection In San AntonioFacet joint injection includes an injection into the spine in the neck, thoracic or low back area that is separate from the disc. There are small joints that support the weight of the body and commonly are sources of pain in at least 50% of the cases. With x-ray guidance, small needles can be placed and depositing cortisone into the joints and if significant improvement is obtained, but not long lasting, a further procedure called radiofrequency can be used to provide longer lasting relief for a period of six months to a year.

What are the causes of facet pain?

Facet joint pain can be caused by overall degeneration of the discs that are the cushions between the vertebrae and therefore the facet joints have to bear more weight of the body; also, repetitive use and premature arthritis or previous injury can accelerate pain of this type, which is commonly the cause of neck, midthoracic and low back pain.

Interventional treatments for facetogenic pain include, as mentioned above, x-ray guided injections to the joint with cortisone and local anesthetic to diagnose and treat the pain and if improvement is obtained that is very significant but not long lasting, a secondary procedure called medial nerve branch radio frequency is applied to numb the nerve that goes to the joint, therefore providing longer lasting relief similar to what a root canal procedure will do to a toothache.
