摘要
目的:探讨臀肌挛缩症(GMC)与髂骨致密性骨炎(OCI)的关系。方法:搜集我院手术确诊的符合本研究纳入标准的GMC患者共315例,非GMC对照组251例,由2位高年资的放射诊断医师阅读两组的术前CT影像资料,分别统计OCI的发生率。随机选取不对称性OCI的GMC患者资料19例,共累及23侧骶髂关节,测量OCI髂骨硬化区与臀大肌,并进行相关性分析。结果:GMC组中OCI 81例(25.7%),其中男16例(16/315),女65例(65/315);对照组251例中有2例OCI(0.7%)。GMC组与对照组之间及GMC组内男女患者之间,OCI的发生率差异均有显著性意义,U值分别为7.42,4.52,P<0.05。OCI髂骨硬化程度与臀大肌的相关分析表明二者呈正相关r=0.61,P<0.01。结论:GMC与OCI有密切关系。
Objective：To study the relationship between gluteal muscle contracture（GMC） and osteitis condensans ilii（OCI） using computed tomography（CT）.Methods：A total of 315 patients with surgically confirmed GMC who met inclusion and exclusion criteria,together with 251 subjects with non-GMC,underwent CT were enrolled.All CT images were read independently by 2 experienced radiologists and OCI numbers were counted.Measurements of OCI sclerosis areas and gluteus maximums were conducted with a randomly selected subset of 19 patients with asymmetry OCIs.For data analysis,he Pearson correlation analysis test was used.A difference with P0.05 was considered significant.Results：Of the 315 cases,81（overall 25.7%,5% for males and 20.6% for females） were diagnosed as OCI（study group）,while 2（0.7%） cases in the control group had evidence of OCI.Female had significantly higher prevalence of OCI than males（P0.05）.There was a significantly positive correlation（r=0.61,P0.01） between OCI sclerosis areas and gluteus maximus sizes.Conclusion：GMC is significantly associated with osteitis condensans ilii.
