Osteitis Condensans Ilii: Case Report

Abstract

Back pain is one of the most frequent complaints during the last period of pregnancy. In a small group of patients the persistent pain during the postpartum period may be secondary to osteitis condensans ilii (OCI), and rarely can occur suddenly in the elderly. OCI is a rare benign pathology, low back or buttock pain should be suspected in patients coming from. Although the exact etiology is unknown, it is suggested that the increased mechanical stress across the sacroiliac joint, depending on the mechanical stress, changes may develop in the iliac bone. In practice, it is important to recognise this disease as it can be potentially confused with similar causes of axial low back pain such as seronegative spondyloarthropathy, metastatic disease, or sacroilitis. Here two woman patients with low back pain and buttock pain secondary to unilateral an uncommon benign condition called osteitis condensans ilii is presented. This report emphasis the salient features and the differential diagnosis in diagnosing and managing this rare pathology.

Rare and overlooked two diagnoses in low back pain: Osteitis condensans ilii and lumbosacral transitional vertebrae

“…OCI is one of the rare causes of low back pain [5,6,8]. It is more common in young age group and female gender [5,6,8].…”

“…OCI is a benign form of low back pain and it is important to distinguish from inflammatory low back pain because of typical radiological findings [5][6][7]. The sacroiliac joint is usually affected by the inferior segment [5,6,8]. Triangular-shaped sclerosis of the iliac bone adjacent to sacroiliac joint is apparent [5,6,8].…”

“…OCI is more frequent in female patients, younger age group and bilaterally [5][6][7][8]. However, unilateral cases have been reported rarely [5].…”

“…Although the mechanism by which LSTV causes back pain is not clearly known, it has been suggested that early degeneration, spinal-extraforaminal stenosis and changes in load distribution caused by instability. Because OCI is often associated with pregnancy and be seen in young female, it has been reported that changes in the distribution of burden of sacroiliac in pregnancy and ligament laxity caused by hormonal factors may play a role in etiology [5][6][7].

Osteitis CondensansIlii - A Rare Presentation

“…They described 15 cases in a period of one and half years. The prevalence of OCI in the general population has been estimated to be between 0.9 and 2.5% 10 . It is essential a radiological diagnosis.…”
