What is a CT guided facet joint/nerve root injection?
The injection consists of a mixture of an anaesthetic and a long lasting steroid either into the facet joints or nerve roots of the spine. Facet joints are located in the spine at each vertebral level. They are paired (right and left) and are surrounded by a joint capsule. Nerve roots are also found at each vertebral level at which nerves leave the spinal cord. Depending on the nature of your symptoms, the doctor will know whether to inject at the facet joint or nerve root. The steroid injected reduces inflammation at the site and thus reduces pain and the associated symptoms.
