A Facet Joint Injection is an injection of local anaesthetic and/or steroid into the Facet Joints, which are located between the vertebral bones of the spine. The injection is usually done to alleviate pain. Commonly, Facet Joint Injections are made into the cervical or lumbar facet joints. Cervical facet joints are located on the back or side of the neck and lumbar facet joints are in the lower back. Pain caused by cervical facet joints is usually felt in the head, neck, shoulder or arm. Pain cause by lumbar facet joints (in the lower spine) is typically felt in the lower back, hip, buttock or leg.
Please inform the booking staff if you are on Warfarin, Plavix, or any other blood thinning agents, or have any other medication allergies.

B. During your Facet Joint Injection
When you are transferred to the CT room you will be made comfortable on the examination table. The examination table slides you into the centre of the CT machine and some preliminary pictures are taken to confirm the scan position and the area of needle entry marked on your skin.
The skin above the facet joint will be washed with antiseptic and a local anaesthetic may be injected. A fine needle is then inserted, guided into position using CT control and once satisfactorily positioned the solution will be injected.
Other risks associated with this procedure include:
Infection is rare but may involve redness or swelling and increased joint pain, usually after 48 hours. Superficial infection is the most common form and responds rapidly to antibiotics; joint infection is extremely rare, but can be severe and result in permanent joint damage. Increasing pain needs to be promptly reported to your referring doctor.
Any medical procedure can potentially be associated with unpredictable risks.
