A dorsal root ganglion block – also sometimes referred to as a nerve root injection, or a transforaminal epidural – is an injection of local anaesthetic and steroid around the dorsal root ganglion, which looks like a small swelling on the nerve that joins the spinal cord and contains nerves that carry sensation. The sensory nerves enter through a hole referred to as the intervertebral foramen, which means anaesthetic and steroid may spread to the epidural space when the injection is carried out (this is why the treatment is also sometimes referred to as a transforaminal epidural). Dorsal root ganglion blocks are used mainly for localised radicular pain (sciatic leg or arm pain) pain, most commonly in the lumbar region, where simpler measures have not helped. Again, the effects can vary from person to person, with some experiencing a long-lasting significant reduction in pain, and the injections are usually undertaken alongside other treatments, such as physiotherapy.
