Abstract
A prospective study was performed to compare the results of quantitative radionuclide bone scanning with those of sacroiliac joint anesthetic block in patients with unilateral low back pain. Thirty-four subjects, forming the control group, underwent quantitative radionuclide bone scanning of the sacroiliac joints. The normal values in sacroiliac uptake difference were taken to be between –1.7% and +6.2%. Thirty-two patients with chronic unilateral low back pain underwent sacroiliac bone scanning and sacroiliac joint block. Six of the seven patients with increased uptake > 6.2% on the painful side had at least 75% pain reduction in response to the block. The sensitivity, specificity, and positive and negative predictive values of the quantitative bone scanning in the unilateral mechanical sacroiliac joint syndrome were 46.1%, 89.5%, 85.7%, and 72%, respectively.
