The results of this review demonstrate that tests do exist that change the probability of the disc or SIJ ( but not the facet joint ) as the source of low back pain .
Clinical practice guidelines state that the tissue source of low back pain can not be specified in the majority of patients .
However , there has been no systematic review of the accuracy of diagnostic tests used to identify the source of low back pain .
The aim of this systematic review was therefore to determine the diagnostic accuracy of tests available to clinicians to identify the disc , facet joint or sacroiliac joint ( SIJ ) as the source of low back pain .
Value of quantitative radionuclide bone scanning in the diagnosis of sacroiliac joint syndrome in 32 patients with low back pain
Abstract A prospect i ve 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
