What Is a Medial Branch Block?

A Medial Branch Block targets the small medial branch nerves that carry pain signals from the facet joints. This is both a diagnostic and therapeutic injection designed to determine whether facet joint dysfunction is the source of your spine pain.

Common Uses

  • Facet joint arthritis
  • Chronic neck pain
  • Chronic lower back pain
  • Pain aggravated by bending or twisting

Why Choose MBB?

  • Helps confirm the exact source of pain
  • May provide immediate short-term relief
  • Determines candidacy for Radiofrequency Ablation (RFA)

What to Expect

A small amount of anesthetic is injected near the medial branch nerves. Significant temporary pain relief confirms facet joints as the source of pain and guides next-step treatment planning.
