多层螺旋CT评价肩关节盂的临床价值

Clinical Value of MSCT in the evaluation for glenoid of shoulder

【目的】探讨多层螺旋CT(MSCT)三维重组技术对肩关节盂形态的评价能力及其临床价值。【方法】回顾性观察73例患者的肩关节CT检查资料,通过轴位、斜冠状及双斜矢状面等多角度重组显示并分析关节盂的形态。【结果】重组图像显示30例肩关节盂骨质结构完整(其中5例临床诊断为关节盂先天发育不良),43例显示关节盂前方或后方形态有不同程度缺损,缺损比例为4.1%～32.5%(平均为15.7%)。【结论】多层螺旋CT三维重组技术能准确、直观评价肩关节盂解剖学形态,有很高的临床应用价值。

[Objective] To discuss the clinical value of MSCT and three-dimensional reconstruction technique in the appreciation for glenoid of shoulder. [ Methods ] CT findings of 73 patients of shoulder were retrospectively studied. The morphology of glenoid in axial view, oblique-coronal view and bilateral oblique-sagittal view were analyzed. [ Results ] 30 patients＇ glanoid bone were integrated（5 patients were diagnosed congenital dysplasia in clinic）,43 patients had to glenoid bone loss of different extent in anterior or posterior direction. The proportion of glenoid bone loss ranged from 4.1% to32.5% （mean 15.7%）. [Conclusion] The anatomic features can be shown accuratly and directly with MSCT and three-dimensional reconstruction technique.
