摘要
目的:探讨股骨颈骨折的临床分型及影像学检查在诊断中的应用。材料与方法:60例股骨颈骨折患者均做X线平片检查,其中20例无移位或嵌顿性股骨颈骨折进一歩做了MRI检查,并依据骨折部位及影像学表现做出分类。结果:在60例股骨颈骨折中,30例为股骨头下骨折,占50%,16例股骨颈中部骨折,14例基底部骨折。股骨头下骨折中15例发生股骨头坏死。结论:股骨颈骨折属髋关节的关节内骨折,最为常见,多见于老年人(特别妇女)。在股骨颈骨折中以头下骨折最为常见且股骨头坏死率很高。移位的头下骨折通常在AP位X线平片上表现明显,而无移位的头下骨折X线改变不明显,常需做进一歩影像检査,诸如MRI。
Purpose： To the classification of femoral neck fractures and imaging studies. Materials and Methods：50 cases with femoral neck fractures were studied by x- ray films,in which 5 patients with nondisplaced or impacted are difficult to see on plain film,further imaging studies,e. g. Magnetic Resonance Imaging（ MRI）,are indicated,and the fractures are classified on the basis of the location and imaging findings. Results： In 50 cases of femoral neck fractures,30 patients are subcapital fractures 50%,10 cases are transscervical fractures, and 10 cases are basicervical. Subcapital fractures have avascular necrosis（ AVN） in 2 cases. Conclusion： Femoral neck fractures are intracapsular fracture. Femoral neck fractures are common in the elderly（ particular women） because of osteoporosis. Subcapital fractures are the most common femoral neck fratures,and the greater the risk of AVN. A displaced subcapital fracture is usually obvious on the AP radiograph. However,nondisplaced fractures can be radiographically inapparent. Further imaging studies, e. g. Magnetic resonance imaging（ MRI）,are indicated.
