Osteitis condensans ilii (OCI) is a rare self-limiting low back pain syndrome. It is an incidental imaging discovery around sacroiliac joints with distinctive sclerotic lesions. We present three case reports as a series. In the first case, a 38-year-old female presented with unresolved chronic low back pain for eight years. She had bilateral triangular sclerosis of the ilium abutting sacroiliac joints and other causes of back pain were ruled out. Non-operative management was successful. In the second case, a 38-year-old female presented with acute exacerbation of low back pain for one year. She suffered low back pain during her pregnancy and postpartum period 16 years ago and intermittently after that. Bilateral radiodensity around sacroiliac joints was noted in the radiograph and she had successful remission with non-operative management. In the third case, a 45-year-old female presented with chronic low back for six years. On radiographs, she had bilateral sclerotic lesions around sacroiliac joints and responded well to non-operative management. OCI is a benign, idiopathic cause of axial low back pain. It is a diagnosis of exclusion and the pelvic radiographs classically show areas of sclerosis in the ilium adjacent to sacroiliac joints bilaterally. Treatment for OCI is essentially non-operative.
致密性骨炎（OCI）是一种罕见的自限性下腰痛综合征。它是骶髂关节周围一种偶然的影像学发现，伴有特征性的硬化性病变。我们报告三例系列病例。第一例，一名38岁女性，有八年未缓解的慢性下腰痛。她双侧髂骨呈三角形硬化，紧邻骶髂关节，排除了其他引起背痛的原因。非手术治疗成功。第二例，一名38岁女性，有一年下腰痛急性加重。16年前她在孕期和产后曾患下腰痛，之后间断发作。X线片显示骶髂关节周围双侧有放射性密度增高影，非手术治疗后病情成功缓解。第三例，一名45岁女性，有六年慢性下腰痛。X线片显示她双侧骶髂关节周围有硬化性病变，非手术治疗反应良好。致密性骨炎是引起轴性下腰痛的一种良性、特发性病因。它是一种排除性诊断，骨盆X线片典型表现为双侧髂骨紧邻骶髂关节处的硬化区域。致密性骨炎的治疗基本上是非手术治疗。
