Summary
In this study, the investigators are attempting to determine whether intra- or
extra-articular injections are more effective; the relative prevalence rate of
intra-articular and extra-articular SI joint pain; and the accuracy of extra-articular
injections using fluoroscopy as the reference standard. 124 consecutive patients with
mechanical low back pain below L5, tenderness overlying the SI joint(s) and at least 3
positive provocative maneuvers will be randomized to receive SI joint injections by 2
different approaches.
Group 1 will receive fluoroscopically-guided injections into the joint. Group 2 will receive
landmark-guided injections into the tender area around the joint. In order to determine
whether the injection in group 2 was intra-articular or extra-articular, an x-ray will be
done after the injection to ascertain the location of contrast spread. The primary outcome
measure will be pain relief at 1-month. Patients who obtain benefit at 1-month will be
followed at 3-months, while those who fail to obtain benefit will exit the study to receive
alternative care.
