摘    要:目的分析成人缺血性股骨头坏死影像学的特征分布情况。方法通过回顾性调查的方法,收集2004年1月至2005年12月在上海六院骨科接受手术治疗的股骨头坏死患者术前的X线、MRI等影像学资料及一般资料,共118例(男77例,女41例)患者,共164髋为研究对象,其中MRI资料为129髋。按照股骨头坏死Steinberg分期进行系统描述,分析股骨头坏死的面积、部位及塌陷与面积之间的关系等情况并进行相应的统计学处理。结果男、女平均年龄分别为36.69岁和36.05岁,患者不同性别的年龄间的差异无统计学意义。164例坏死股骨头中,其中Ⅰ期为3例,Ⅱ期34例,Ⅲ期27例,Ⅳ期93例,V期7例,以Ⅲ、Ⅳ期为主(占73.17%)。在股骨头坏死区域的分布方面,位于股骨头上外侧、上外侧加头下靠近中央区等压力承重区域占76.83%(126例);在坏死面积方面,大于30%的坏死面积占84.15%(138例);在外形有塌陷方面,外形有塌陷者占60.98%(100例)。外形有塌陷者与非塌陷者在坏死面积方面比较,塌陷者坏死面积大,两者之间的差异有统计学意义(P〈0.01)。MRI检查发现股骨头骨髓水肿的患者占39.56%,有股关节积液的患者占61.54%。结论本组患者在坏死分期方面以Steinberg Ⅲ、Ⅳ期为主(73.17%)。股骨头坏死主要集中在应力承重区域,本组138例患者(占84.15%)的坏死面积大于30%以上,坏死面积越大者外形越容易发生塌陷。

关 键 词:股骨头坏死  影像学特征  回顾性研究  流行病学研究
