磁共振三维血管成像技术评估股骨颈骨折股骨头血运状态

背景:国内外临床上判断股骨颈骨折后股骨头局部血运的方法较多,但使用时缺点较多,尤其是不能准确判断股骨颈骨折后周围2,3级血管的情况。目的:利用磁共振三维血管成像技术评估股骨颈骨折股骨头血运状况,为手术方式的选择提供依据。方法:选择2008-07/12宜春学院临床医学院收治的未行磁共振及三维血管成像检查16例股骨颈骨折患者,行闭合复位两枚双头加压螺钉固定(对照组)。选择2009-01/2011-02收治的行磁共振及三维血管成像检查的股骨颈骨折患者33例,根据检查结果对患侧旋股内侧动脉情况良好的30例行闭合复位两枚双头加压螺钉固定(实验组),另3例行髋关节置换。结果与结论:对照组中11例骨性愈合,5例出现股骨颈吸收,需行二次手术;实验组中29例骨性愈合,1例需行二次手术。说明磁共振三维成像技术能够清晰地显示骨颈骨折周围2～3级血管成像,指导手术选择,对预后做出较准确判断,减少二次手术的发生。

Three-dimensional vascular magnetic resonance assessment of the blood supply following femoral neck fracture

BACKGROUND:Clinical judgments of local blood supply after femoral neck fracture are many;however,the disadvantages of these methods are also a lot.Especially,it cannot accurately judge the blood supply of 2-3 grade blood vessels around femoral neck fracture.OBJECTIVE:Using three-dimensional magnetic resonance angiography to study the blood circulation of the femoral head after femoral neck fracture,providing a basis for the choice of surgical approaches.METHODS:Sixteen patients with femoral neck fracture ad...
