Sacroiliac Joint Pain Following Iliac-Bone Marrow Aspiration and Biopsy: A Cohort Study

Abstract

Background: Sacroiliac joint (SIJ) pain is a common source of lower back pain; the factors associated have not been studied in cancer patients. Observing patients with bone marrow aspiration and biopsy (BMAB) who subsequently developed SIJ-pain led to this investigation. Aim: To investigate this possible relationship. Methods: A cohort study of cancer patients diagnosed with SIJ pain. The association of BMAB with SIJ pain was evaluated, as were variables that differed between the groups. Results: The prevalence of SIJ pain was 4.95% (231/4669). Among 231 patients with SIJ pain, 34% (78/231) did not have prior history of lower back pain and had undergone BMAB prior to their diagnosis of SIJ pain. A statistically significant association between BMAB–SIJ-pain was found (p < 0.01). Conclusion: We found linear correlation between BMAB and subsequent SIJ pain.
