Facet joint injections/medial branch blocks
Inflammation of the small joints between spinal bones called facets can cause neck pain, mid-back pain and/or low back pain. Facet Injections and Medial Branch Blocks are a method of diagnosing which facet joint along the spine is causing the pain and can even potentially eliminate the pain at the same time.
A facet injection – a small amount of local anesthetic and steroid medication is injected into the joint.
A medial branch block uses similar medication injected outside the joint space near the nerve that feeds a specific joint.
Both injection procedures are performed using fluoroscopy.
If pain is relieved, it could mean that the joint or medial nerve generates pain.
