Osteitis Condensans Ilii

Osteitis condensans ilii results in recurrent axial low-back pain. It mostly affects women and is found incidentally on plain X-ray by observing iliac bone sclerosis and a normal sacroiliac joint.


Presentation

Osteitis condensans ilii (OCI) is a benign cause of low-back pain that is self-limiting and has an unknown etiology. It lacks pathological or clinical evidence of inflammation.

The major clinical presentation in OCI is low back pain of mechanical character that is aggravated by activity and relieved upon resting. The patients often describe the non-radicular back pain as radiating down to the posterior thighs.

Usually, the iliac bone near the sacroiliac joint is affected in a bilateral and symmetric process. OCI is predominant in women of child-bearing age. However, rare incidents of men and nulliparous women with OCI is possible. OCI may be unilateral [1].

The sacrum may also be involved since the changes are not always limited to the iliac bones. The joint spaces are generally normal. However, an occasional lipping, and narrowing of the lower margin or minimal irregularities may be observed. Cases have long remissions and even though the onset can be associated with pregnancy, subsequent pregnancies do not necessarily worsen the symptoms. There are no collateral and consistent systemic disturbances or physical and radiological findings [2].

The pregnancy-associated ligamentous laxity of the sacroiliac joint (SIJ) can result in persistent instability and sclerosis of the joint in some cases. This can later present as SIJ tenderness. The course of the disease is chronic and it may relapse.Therefore, OCI should be differentiated from other inflammatory or non-inflammatory disorders of the sacroiliac joint [2] [3].

Workup

The diagnostic criteria of OCI includes [3] [4]:

  • Unilateral or more commonly bilateral
  • Sclerosis of the lower margin of the iliac bone and a normal sacroiliac joint on radiological imaging
  • Predominance in females
  • Normal inflammatory parameters
  • Negative HLA-B27 antigen
  • Normal bone scan
  • Absence of bone erosion or destruction

In addition, a thorough history and physical examination can help differentiate OCI from ankylosing spondylitis, sacroiliitis, seronegative spondyloarthropathies, primary hyperparathyroidism, renal osteodystrophy, Paget's disease, bone secondaries and lymphoma [3] [5] [6] [7] [8]. Normal blood tests and seronegativity can exclude most of these conditions.

The radiographical appearance of OCI is described as a well defined triangular sclerosis of the iliac bone in the sacroiliac joint. Eburnation can be observed in the inferior part of the bone. Sclerosis can extend to the auricular portion of the iliac bone. Unlike other forms of sacroiliitis, the joint space is not obliterated in OCI and the articular margins remain intact. The radiological features of OCI can resolve over time [9].

In a small group of patients affected with OCI, polyarthralgia in the peripheral joints has been reported. However, significant inflammatory articular changes are usually absent.

Treatment

  • Of 100 patients revielled, eight showed no response to treatment and twenty-three were somewhat improved; in sixty-seven patients conservative treatment afforded either complete relief or marked amelioration of symptoms.[insights.ovid.com]
  • Due to the inefficacy of the medical and physical treatment, two patients underwent surgical resection of the osteitic bone; then followed by a 45 days cast immobilization and a 3-4 months with restricted load.[moh-it.pure.elsevier.com]
  • Treatment: In the majority of patient, conservative treatment has been employed. The most important single measure has been the correction, where possible, of obvious postural defects.[medigoo.com]

Etiology

  • Osteitis condensans ilii (OCI) is a benign cause of low-back pain that is self-limiting and has an unknown etiology. It lacks pathological or clinical evidence of inflammation.[symptoma.com]
  • They found nothing suggesting an etiologic factor. Shipp and Haggart (6) later reviewed this same material and extended the series to cover 100 cases.[pubs.rsna.org]
  • Although no clear etiology has been identified, the prevailing theory is that mechanical strain affects the auricular portion of the ilium and causes premature arthritis.[read.qxmd.com]
  • Etiology: The cause is unknown. It may be owing to increased mechanical stress across the sacroiliac joint during pregnancy. It is usually associated with pregnancy but has also been reported in those with hydroxyapatite crystal deposition disease.[rheumaknowledgy.com]
  • The underlying etiology is believed to be mechanical stress across the sacroiliac joint. That it is most often seen in women who have given birth supports this hypothesis; however, men and nulliparous women can be affected 2-4.[radiopaedia.org]

Pathophysiology

  • The pathophysiology of OCI has been described as unknown and the research is vague. It has been postulated that the gravid uterus may compress the abdominal aorta and cause ischemia in the inferior portion of the ilium.[clinicalmaze.com]
  • The pathophysiology of OCI has still not been fully established with the most commonly accepted reasoning being that the mechanical stress of pregnancy itself or uterus causes compression of abdominal aorta resulting in bony remodeling due to ischemia[austinpublishinggroup.com]
  • The pathophysiology of OCI is unknown. 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 ].[ncbi.nlm.nih.gov]

Prevention

  • MAINTENANCE AND RELAPSE PREVENTION Although the cessation attempt is relatively straightforward when patients are motivated to quit, data suggest that maintenance strategies and relapse prevention techniques must be considered from the start.[consultant360.com]

  • To have strong bones when you are young, and to prevent bone loss when you are older, you need to get enough calcium, vitamin D, and exercise. You should also avoid smoking and drinking too much alcohol. Bone diseases can make bones easy to break.[icdlist.com]
