Facet Hypertrophy: When Is Surgery Necessary?

Facet hypertrophy—enlargement of the spinal facet joints—is a common age-related finding. Most cases are managed conservatively; surgery is reserved for refractory symptoms with confirmed structural compression.

Conservative Management (First-Line)

• Physical therapy: core stabilization, posture correction, mobilization.
• NSAIDs or acetaminophen for pain/inflammation.
• Activity modification; avoid prolonged extension/rotation.
• Medial branch blocks (diagnostic and therapeutic).
• Radiofrequency ablation (RFA) of medial branches for longer relief.

Surgical Indications

• Progressive neurological deficit (rare from isolated facet hypertrophy).
• Intractable pain after ≥6 months of failed multimodal conservative care.
• Documented nerve root or cauda equina compression on imaging correlating with symptoms.
• Concomitant instability requiring fusion.

Surgical Options

• Facetectomy (partial/complete) with or without fusion.
• Minimally invasive decompression.
• Interspinous spacers (indirect decompression).

Key Point

Asymptomatic facet hypertrophy on imaging does not warrant treatment. Clinical correlation is mandatory.
