Distribution of Referred Pain from the Lumbar Zygapophyseal Joints and Dorsal Rami

Abstract

A total of 71 joints and 91 medial branches were studied in 48 patients. The distribution of referred pain from the L1/2 to L5/S1 zygapophyseal joints, and the medial branches of the dorsal rami from L1 to L5 were similar for each level stimulated, and the overlap of referred pain between each level was considerable.
