Facet Nerve Block Injections
The facet joint is formed by the attachment of one vertebra to the vertebra above and the vertebra below. This forms the protective back wall of the spinal column. The joint is a true joint containing hyaline cartilage, a synovial membrane/sac, a fibrous capsule and nocioceptive fibers (pain nerves). The nerves can transmit painful signals to the brain. The pattern of pain appears to overlap considerably with the presentation of pain due to other causes.
