“…Overweight cases had significantly less favourable BASFI in this study; this finding has been confirmed by many other studies [4,7]. This could be related to increased strain on both joints with induction of sacral side sclerosis.…”

“…It has been postulated that the gravid uterus may compress the abdominal aorta and cause ischemia in the inferior portion of the ilium; however, this has never been substantiated [11,12]. Other studies have suggested that mechanical stress of pregnancy itself may overload the sacroiliac articulation and cause the disorder [3,4]. Gillespie and Lloyd-Roberts described 21 cases, all occurring in females who had borne children; they felt that the probable pathogenesis was an obliterative endarteritis that follows parturition [13].…”

Purpose Osteitis condensans Ilii (OCI) is an orthopaedic mystery until now and the refractory type poses a great challenge in its management. Surgical resection and sacroiliac arthrodesis are major procedures with no guarantee of success for an unknown disease entity with a normal sacroiliac joint. The aim of this retrospective study was to evaluate results of a novel mini-invasive surgical approach for the refractory type after failure of conservative management. Materials and Methods Fourteen females were included with an average age 35.5±5.8 years. Nine cases were multiparous and five were nulliparous. The pathology was bilateral in all cases; however, seven cases suffered bilateral symptoms, while seven cases had only unilateral com-

“…These results were all comparable with previously reported large series of OCI. [3][4][5]8,14 Four cases (14.8%) were HLA-B27 antigen positive (two cases demonstrating BME and two cases not). This seems higher than most literature reports, but was comparable with Singal et al 4 who reported the distribution of HLA-B27 antigens in a group of 37 female patients; four of the 25 OCI patients (16%) were B27 positive while 11 of 12 ankylosing spondylitis patients (92%) were B27 positive.…”

“…In the next following 90 years, more characteristics have been added to this disease, including female or even post-delivery predominance, human leukocyte antigen (HLA)-B27 negativity, normal inflammation markers and characteristic radiographic findings not associated with bony destruction or erosion. [2][3][4][5][6][7][8] Although till now the definite etiology of OCI has been unclear, its benign outcome without disabling progression or even self-limitation is widely accepted. [5][6][7][8] OCI is generally asymptomatic, but some OCI patients complain of low back pain (LBP) at a young age mimicking, axial spondyloarthritis (SpA).…”

Aim: To reveal whether bone marrow edema (BME) may appear with osteitis condensans ilii (OCI) on sacroiliac joint (SIJ) magnetic resonance imaging (MRI) and to evaluate the characteristics of BME demonstrated with OCI.Method: Altogether 27 symptomatic female OCI patients with both complete clinical records and SIJ-MRI examination data were enrolled for retrospective analysis. SIJ-MRI exams were retrospectively analyzed by two musculoskeletal radiologists. Patients were separated into BME group and non-BME group according to whether there was BME of SIJ demonstrated as high signal intensity on MR short tau inversion recovery sequences beneath the SIJ articular surface. For the BME group the characteristics of BME including distribution pattern and location, depth and signal intensity were assessed.Results: BME could be seen in 48.1% (13/27) OCI patients. Ilium side BME demonstrated with OCI was centered at the ventral-cartilaginous joint part and had a trend of extending to bone marrow beneath the arcuate line in a continuous distribution pattern. There was a trend that OCI patients with BME demonstrated on MRI were younger (P = 0.054, Student's t-test) and with shorter pain duration (P = 0.091, Student's t-test) than OCI patients without BME, but the differences did not reaching statistical significance. More cases endured diagnosis delay in the BME group than the non-BME group (nine cases vs. two cases, P = 0.006, Fisher's exact test). Conclusion: Some OCI may demonstrate BME on SIJ-MRI. Careful observation of the location and distribution pattern of BME may give some help in differentiating OCI from early spondyloarthritis.
