Facet Joint Pain & Hypertrophy Treatment in Naples & Marco Island

What facet hypertrophy actually is.

Facet hypertrophy is the medical term for enlargement of the facet joints, typically as a result of degenerative change. Over time, repetitive load on the spine — particularly with aging, prior injury, or disc degeneration that shifts mechanical load onto the facets — causes the joint cartilage to wear, the underlying bone to remodel, and bone spurs (osteophytes) to form. The joint becomes larger, irregular, and often arthritic.

Facet hypertrophy is one of the most common findings on lumbar and cervical MRI in adults over 40. So common, in fact, that many people with hypertrophy on imaging have no symptoms at all. The presence of facet hypertrophy on an MRI does not automatically mean it is the source of pain. The clinical question is always whether this particular patient's pain pattern is consistent with facet involvement — and whether a diagnostic block confirms it.

How facet joint pain typically presents.

Facet joint pain has a recognizable pattern, though the pattern varies somewhat by spinal level.

Lumbar facet pain typically produces deep, dull low back pain that may radiate into the buttocks or upper thighs (rarely below the knee — distal radiation into the foot is more typical of disc or nerve root problems). The pain is often worse with extension (arching backward), prolonged standing, or twisting, and often eases with sitting or forward bending. Patients commonly describe pain that is worse first thing in the morning with stiffness, eases with movement, and worsens again at the end of a long day.

Cervical facet pain typically produces neck pain that may radiate into the upper shoulder, shoulder blade, or upper arm, often with associated headaches at the base of the skull (cervicogenic headache). It is often worse with neck extension and rotation, and may be triggered or worsened by a prior whiplash-type injury.

Patients with facet pain often describe a pattern of "good days and bad days," with flares triggered by specific positions or activities. The pain is rarely electric or shock-like in quality — that pattern is more typical of nerve pain. Facet pain is more often described as a deep ache, stiffness, or pressure.

Why "facet hypertrophy on imaging" is not the same as "facet pain."

A common source of confusion: facet hypertrophy is extremely common on imaging, and it can coexist with other causes of back pain (disc disease, sacroiliac dysfunction, muscle dysfunction, central sensitization). The fact that hypertrophy shows up on your MRI does not, by itself, mean the facets are driving your pain. The connection is established clinically — through a careful exam combined with a diagnostic procedure when indicated.

How facet joint pain is diagnosed.

Diagnosis of facet-mediated pain is a clinical process. It begins with a detailed history (the pattern, the triggers, the prior workup), a focused exam (looking for tenderness over the joints, pain with extension and oblique loading, and signs that point toward or away from facet involvement), and a review of available imaging.

When facet involvement is suspected, the diagnostic medial branch block is considered the gold standard test. The medial branches are small nerves that carry sensation from each facet joint. By delivering local anesthetic precisely to these nerves under fluoroscopic guidance, we can temporarily numb the facet joints at the suspected level. If your typical pain substantially improves for the duration of the local anesthetic — usually a few hours — the facets are confirmed as the dominant pain generator. If the pain does not improve, the facets are not the source, and the workup moves elsewhere.

Diagnostic medial branch blocks are typically performed twice on separate days at the same level. This double-block approach reduces false positives and is the standard before proceeding to definitive treatment.
