Frequency of Sacroiliitis in Low Back Pain Due to Prolonged Sitting ORIGINAL ARTICLE Frequency of Sacroiliitis in Low Back Pain due to Prolonged Sitting Nabiha Mujahid Faruq,1 Parkash Israni2 and Nosheen Zehra3 ABSTRACT Objectives: To assess the frequency of Sacroiliitis in patients with Low Back Pain (LBP) due to Prolonged Sitting Methodology: A cross-sectional study was conducted in Physiotherapy Department of Ziauddin University Hospital among patients with history of low back pain and continuous sitting for minimum 3 hours. Data was collected from 216 patients who were selected through convenience sampling technique. A pre tested and structured questionnaire was used to collect data. Data was entered and analyzed by using SPSS version 17. Results: It was found that out of 216 patients, 127 (58.8%) had sedentary work. Mean of pain intensity in VAS scale was found as 4.81 ±1.63. It was observed that sitting has been the most aggravating factor for LBP and it was relieved by rest, physiotherapy and medication. Association of frequency of LBP with gender and daily continuous sitting was found significant with p-value=0.03 and 0.00 respectively. Among LBP patients Faber’s test was used for diagnosis of Sacroiliitis. Faber’s test association with type of work was found significantly positive in those with sedentary work with p-value=0.031. Conclusion: The study showed that there was significant association of prolonged sitting with Sacroiliitis in patients with LBP. Key words: Low back pain, prolonged sitting, sacroiliitis.

INTRODUCTION accepted that about 13% (95% CI: 9-26%) of patients with persistent low back pain have the origin of pain Low back pain (LBP) refers to the pain felt in lower confirmed as the SIJ.5,15 Risk factors of Sacroiliitis back region. Such pain or discomfort affects the lower include poor posture, weak muscles, bending or twisting back as it supports most of our body's weight. Sitting the back, improper lifting, Ankylosing spondylitis, has been associated with risk of developing LBP.1 history of bone, joint or skin infections, Injury or Other risk factors of LBP may include old age, family trauma, Urinary tract infection, Pregnancy, obesity and history, pregnancy, compression fractures, back surgery, Illicit drug use.2 Treatment options may include various congenital deformity, sedentary lifestyle, poor posture ways of relieving inflammation. Non-steroidal Anti- and physical stress.2 inflammatory drugs can be useful in some cases.

The relationship with Sacroiliitis. There may be some severe cases that between the sacroiliac joint (SIJ) and low back pain may require cortisone injection to block nerve pain. has been a subject of debate among some researchers The reason behind this research is to assess the regarding SIJ pain as a major contributor to the low association between sitting and presence of LBP and back pain problem3 with others regarding italso as frequency of Sacroiliitis in LBM.

  • Sacroiliitis Mimics: a Case Report and Review of the Literature Maria J
    Antonelli and Magrey BMC Musculoskeletal Disorders (2017) 18:170 DOI 10.1186/s12891-017-1525-1 CASE REPORT Open Access Sacroiliitis mimics: a case report and review of the literature Maria J. Antonelli* and Marina Magrey Abstract Background: Radiographic sacroiliitis is the hallmark of ankylosing spondylitis (AS), and detection of acute sacroiliitis is pivotal for early diagnosis of AS. Although radiographic sacroiliitis is a distinguishing feature of AS, sacroiliitis can be seen in a variety of other disease entities. Case presentation: We present an interesting case of sacroiliitis in a patient with Paget disease; the patient presented with inflammatory back pain which was treated with bisphosphonate. This case demonstrates comorbidity with Paget disease and possible ankylosing spondylitis. We also present a review of the literature for other cases of Paget involvement of the sacroiliac joint. Conclusions: In addition, we review radiographic changes to the sacroiliac joint in classical ankylosing spondylitis as well as other common diseases. We compare and contrast features of other diseases that mimic sacroiliitis on a pelvic radiograph including Paget disease, osteitis condensans ilii, diffuse idiopathic skeletal hyperostosis, infections and sarcoid sacroiliitis. There are some features in the pelvic radiographic findings which help distinguish among mimics, however, one must also rely heavily on extra-pelvic radiographic lesions. In addition to the clinical presentation, various nuances may incline a clinician to the correct diagnosis; rheumatologists should be familiar with the imaging differences among these diseases and classic spondylitis findings.
