股骨颈骨折CT影像分析及临床意义

The assessment of bone defects in femoral neck fracture by CT images

目的 在追求理想解剖复位前提下,借助电子计算机X射线断层扫描技术（CT）影像对股骨颈骨折骨缺损情况进行评估.方法 对我院150例股骨颈骨折患者行螺旋CT扫描.借助CT影像对股骨颈骨折进行分类,提出潜在骨缺损及真性骨缺损的概念,并对各类骨缺损的发生部位进行统计.结果 在150例股骨颈骨折患者中,存在潜在骨缺损99例,占66.00％;有真性骨缺损26例,占17.33％,以颈后方缺损最为多见（12例,8.00％）.结论 螺旋CT影像可以直观、立体的反映骨折、骨缺损形态.股骨颈骨折潜在骨缺损发生率较高.

Objective Under the premise of the pursuit of the ideal anatomical reduction,assess the bone defects of femoral neck fracture with CT imaging.Methods 2009.1-2011.12,do spiral CT scan to 150 cases of femoral neck fractures in our hospital.Classify the femoral neck fracture with CT imaging,put forward the concept of potential bone defects and true bone defect,and count the occurred parts and the degree of various types of bone defects.Results In 150 cases of femoral neck fracture,there were 99 cases of potential bone defect,66.00％ of the total cases; Posterior defects were the most common （48 cases,48.5％）,26 cases of true bone defect,17.33％ of the total cases,posterior defects were the most common （12 cases,8.00％）.Conclusion Spiral CT images can reflecte the form of fractures and bone defects intuitively and three-dimensionally.Femoral neck fracture has a high incidence of potential bone defect,attention should be paid to it.
