Medial Branch Blocks

Pain from the spine may, in some cases, arise due to wear and tear or dysfunction of the facet joints.  In some cases this can be helped by injection into or just around the facet joints, and this is discussed on this page.  

As an alternative, we sometimes do injections to the small nerves that supply the facet joints, called the medial branch.  These come off the nerves (the "dorsal primary ramus") that emerge from the sides of the spinal column and pass backwards to supply the facet joints.

In some circumstances, it may be appropriate to do a procedure called medial branch denervation to try to give long-lasting reduction in pain from the facet joints.  This is dealt with in more detail here.
