El papel de la sintomatología depresiva, catastrofi smo y expectativa en la efi cacia de las técnicas intervencionistas para el tratamiento del dolor lumbar crónico
Objective
To assess clinical improvement after ultrasound-guided injection of corticosteroids into the sacroiliac joint of patients with spondyloarthritis.
Methods
Observational, descriptive, retrospective study of patients with spondyloarthritis and sacroiliitis who received an ultrasound-guided injection into the sacroiliac joint between June 1, 2020 and May 31, 2021. Means were compared using the t test for the variables VAS, BASDAI, ASDAS, CRP, and ESR before and after the procedure. We evaluated the association between these variables and the clinical response using the odds ratio.
Results
We analyzed 32 patients with spondyloarthritis (age 42.69 ± 8.19 years; female sex, 56.25%) with a VAS score of 7.88 ± 0.79, BASDAI of 5.43 ± 1.48, and ASDAS of 3.27 ± 0.86 before the procedure. At 2–3 months, 75% of patients had improved: VAS 3.81 ± 2.33 (–4.07, p < 0.0001) and BASDAI 3.24 ± 1.6 (–2.19, p < 0.0001). At 5–6 months, 59.37% had improved: VAS 4.63 ± 2.31 (–3.25, p < 0.0001), BASDAI 3.57 ± 1.67 (–1.86, p < 0.0001), and ASDAS 2.27 ± 0.71 (–1.0, p < 0.0001). Bone marrow oedema resolved in 87.5% of cases compared with the previous magnetic resonance scan. No significant association was identified with the clinical response to the injection.
Conclusions
Ultrasound-guided injection of corticosteroids into the sacroiliac joint of patients with spondyloarthritis and active sacroiliitis leads to an improvement in symptoms that is maintained at 5–6 months. The procedure is effective, safe, inexpensive, and easy to apply.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
