Prospective case series.
The study aimed to investigate the therapeutic efficacy of sacroiliac joint (SIJ) blocks with triamcinolone acetonide in patients with SIJ pain without spondyloarthropathy.
Numerous studies have demonstrated that SIJ blocks with corticosteroid/anesthetic provide long-term pain relief in seronegative spondyloarthropathy. However, only one report on SIJ dysfunction patients without spondyloarthropathy shows promising results.
We conducted a prospective observational study of patients at a University Spine Center from March 2005 to May 2006. The above mentioned SIJ blocks were performed in 150 patients, and dual SIJ blocks confirmed SIJ pain in 39 patients (26%).
Twenty-six patients (66.7%) experienced significant pain reduction for more than 6 weeks; the overall mean duration of pain reduction in these responders was 36.8 ± 9.9 weeks. SIJ blocks were ineffective in 13 patients (33.3%); the mean duration of pain reduction in these patients was 4.4 ± 1.8 weeks. Univariate analysis revealed that treatment failure was significantly associated with a history of lumbar/lumbosacral fusion (P = 0.03).
SIJ blocks with triamcinolone acetonide are beneficial for some patients with SIJ pain without spondyloarthropathy. The SIJ blocks showed a long-lasting efficacy in two-thirds of the patients; however, the duration of its efficacy was shorter in patients with a history of lumbar/lumbosacral fusion. These findings suggest the need for further studies.
Sacroiliac joint blocks with triamcinolone acetonide are beneficial for treating some patients with sacroiliac joint dysfunction without spondyloarthropathy. The sacroiliac joint blocks showed long-lasting efficacy in two-thirds of the patients. The blocks have poor efficacy in patients with a history of lumbar/lumbosacral fusion.
