Spinal Injections

Nerve Root Block

Nerve roots are the parts of the nerves which emerge from the spinal cord. Conditions such as prolapsed discs can cause inflammation and irritation of the nerve roots. A nerve root block or injection is where a mixture of local anaesthetic and steroid is injected around the swollen nerve root to help relieve pain and inflammation.

Medial Branch Block

The procedure of medial branch block involves the injection of local anaesthetic around the nerves that supply feeling to the facet joints. Facet joints are small joints of the spine that provide stability and help guide motion. They are found in the neck (cervical), upper back (thoracic) and lower back (lumbar spine). Each facet joint has feeling supplied by two or three medial branch nerves. Therefore blocking the medial branch to the facet joint will require 3 injections.

Facet Joint Injection

Facet joints are small joints of the spine that provide stability and help guide motion. They are found in the neck (cervical), upper back (thoracic) and lower back (lumbar). They can become painful as a result of arthritis, injury or mechanical stress. With this procedure a mixture of local anaesthetic and cortisone (steroid) are injected into the facet joint. Multiple injections may be required.

Epidural Injection

An epidural injection is where a mixture of a local anaesthetic and a steroid, such as cortisone, is injected into the space surrounding the spinal cord (epidural space). Epidural injections are useful to settle down pain that is associated with inflammation within the lumbar spinal canal.
