Clinical Features of Patients With Pain Stemming From the Lumbar Zygapophysial Joints. Is the Lumbar Facet Syndrome a Clinical Entity?

Spine (Phila Pa 1976). 1994 May 15;19(10):1132-7. doi: 10.1097/00007632-199405001-00006.

Abstract

Study design: This study is a prospective cross-sectional analytic study.

Objectives: The authors determined the prevalence and clinical features of patients with pain stemming from the lumbar zygapophysial joints.

Summary of background data: Previous studies have demonstrated a wide range of prevalence for zygapophysial joint pain and conflicting results with regard to clinical signs.

Methods: One hundred and seventy-six consecutive patients with chronic low back pain were investigated with a series of screening zygapophysial joint blocks using lignocaine and confirmatory blocks using bupivacaine.

Results: Forty-seven percent of patients had a definite or greater response to the screening injection at one or more levels but only 15% had a 50% or greater response to a confirmatory block. Response to zygapophysial joint injection was not associated with any single clinical feature or set of clinical features.

Conclusions: The zygapophysial joint is an important source of pain but the existence of a "facet syndrome" must be questioned.
