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].

  She had never complained of any numbness or “pins and needles” nor weakness in her legs. She had no history suggestive of morning stiffness or other joint involvement. She had no family history of joint disorders. [pmj.bmj.com]

• Localized Pain

  Radiating pain was the first to improve abruptly after surgery, followed by gradual simultaneous amelioration of local pain and stiffness. [ncbi.nlm.nih.gov]

• Wound Infection

  The non-operated asymptomatic side had spontaneous remodelling There were no substantial complications among the studied cases; however, two overweight cases had superficial wound infections. [ncbi.nlm.nih.gov]

• Chronic Infection

  The theories regarding the relationship of vascular occlusion, juvenile epiphysitis and chronic infection are discussed. The probable role of pregnancy is considered. Some points in the differential diagnosis are considered. [birpublications.org]

• Joint Tenderness

  CONCLUSION: Osteitis condensans ilii is associated with tenderness during sacroiliac joint compression tests and should be considered in the differential diagnosis when sacroiliac joint tenderness is elicited. [ncbi.nlm.nih.gov]

  While usually an incidental finding, patients with osteitis condensans ilii are more likely to have sacroiliac joint tenderness compared to controls. [roentgenrayreader.blogspot.com]

  CONCLUSION: Osteitis condensans ilii is associated with tenderness during sacroiliac joint compression tests and should be considered in the differential diagnosis when sacroiliac joint tenderness is elicited. [1] References [wikigenes.org]

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.

His presentation is well gro- ded in the basic sciences and in pathophysiology, an approach which brings a - markable coherence to the text. Correlative imaging concepts are also carefully th- aded through these chapters. [books.google.de]

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]

Still, the pathophysiology of OCI is not clearly understood, but the increased mechanical stress on ileum is considered one of the causative factor of OCI in pregnant women. [cureus.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]

Prevention Flexibility in athletes is the most important step toward prevention of osteitis pubis. Proper body mechanics must be stressed in athletes who participate in activities that yield a higher incidence of this condition. [emedicine.medscape.com]
