摘要
目的:分析肘关节恐怖三联征的影像学表现及其临床诊断价值,旨在提高对本病的影像学认识。方法:对2009年1月-2012年3月在本院就诊并行手术治疗的19例肘关节恐怖三联征患者的影像学资料进行回顾性分析,所有患者均行X线片及螺旋CT扫描并进行多平面重组(MPR)和三维重组(SSD),分析其影像学表现,评价其诊断价值。结果:19例患者中桡骨头骨折按Mason法分型:Ⅰ型2例,Ⅱ型8例,Ⅲ型9例;X线片诊断准确16例,CT均诊断正确。尺骨冠状突骨折按Regan-Morrey法分型:Ⅰ型9例,Ⅱ型8例,Ⅲ型2例;X线片诊断正确15例,CT均诊断正确。结论:肘关节恐怖三联征具有较典型的影像学表现,X线片与螺旋CT扫描尤其是其MPR和SSD图像相结合,更能显示桡骨头和尺骨冠状突的细小骨折以及对其分型更为准确,为骨科医师提供了立体、直观的图像,有助于肘关节恐怖三联征的明确诊断和临床治疗方案的制定。
Objective：The purpose of this study is to improve the imaging diagnosis of terrible triad of the elbow by analyzing the value of imaging findings of this disease in clinical diagnosis. Methods：We reviewed retrospectively the imaging data of 19 patients with terrible triad of the elbow who accepted surgery in our hospital from January 2009 to March 2012. All patients underwent X-ray examination and spiral CT scan as well. The data of CT was reconstructed in multiplanar re-construction （MPR） and shaded surface display （SSD）. Results：Of 19 cases of the radial head fractures, 2 cases were in type Ⅰ ,8 in typeⅡ and 9 in type Ⅲ ,according to Mason classification;the diagnosis of X-ray was correct in 16 cases,and that of CT was in all cases. The ulnar coronoid process fractures were 9 in type Ⅰ ,8 in type Ⅱ and 2 in type Ⅲ according to Regan-Morrey classification;the diagnosis of X-ray was correct in 15 cases, and that of CT was in all cases. Conclusion： Terrible triad of the elbow has classic imaging presentations. X-ray plain film and spiral CT combined with MPR and SSD techniques can display the small fractures of the radial head and ulnar coronoid process accurately. Three-dimensional and intuitive ima-ges may be helpful for orthopaedics in diagnosis and setting therapy plans of terrible triad of the elbow.
