What is an Intra-Articular Joint Injection?
Injections into joints are called intra-articular injections. If you have a swollen or painful joint the radiologist may inject a steroid medication into the joint. Sometimes the doctor may inject a local anaesthetic (numbing medicine) along with the steroid.

What is a Caudal Epidural Injection?
You may have been referred by your Consultant for a Caudal Epidural to relieve symptoms of lower back, buttock, and/or leg pain as a result of injury, inflammation of the nerves, or compression of the nerves from a bulging disc. The site of injection is at the bottom of the spine (the tail bone) into the epidural space. The epidural space is located around the outer covering of the spinal cord and the nerve roots which exit the spine. The local anaesthetic acts on the nerves and may temporarily block their function and cause short term relief from pain. The steroid decreases inflammation and improves the chances of long term relief from the injection.
What is a Pubic Symphysis Injection?
You may have been referred by your Consultant for an injection to relieve the symptoms discussed with you by you referring doctor. The site of the injection is at the pubic symphysis, a small joint at the front of the pelvis where two bones meet. Please see the diagram below.
What is a CT guided spinal injection?
A spinal injection is an injection of local anaesthetic and steroid (anti-inflammatory medication) into or around a part of your spine (neck, back or lower back) which will hopefully relieve the pain and/or symptoms which you are experiencing. The injection will either be into the facet joints or around the 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 exit the spine from the spinal cord and are also found at each vertebral level. 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 in the medium to long term.
