Facet joint injections
Facet joints act as connectors between the bones in your spine. Those in the cervical spine allow your neck to bend and twist but help keep it from moving too far in any direction. Nerve roots pass through the facet joints as they travel from the spinal cord to your head, arms, and other areas.
Like those contained in epidural steroid injections, the medications used for these injections reduce inflammation and temporarily control pain.
The facet joints are found in the spine, where they connect the backbones to each other. They allow the spine to bend and twist. Like a knee or hip, facet joints have cartilage between the bones and a fluid-filled capsule to allow for smooth movement. When damaged, facet joints can cause debilitating pain in the neck or back. This may occur due to an injury, overuse, or the onset of an inflammatory condition.
