摘要
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.
