多层螺旋CT三维重建技术在股骨颈骨折手术中应用研究

目的研究多层螺旋CT(MSCT)三维重建技术股骨颈骨折手术中的应用价值。方法以本院2013年1月-2015年5月收治的100例股骨颈骨折患者为研究对象,均接受X线、MSCT检查,以手术结果为金标准,比较X线、MSCT三维重建技术对股骨颈骨折解剖分型、Garden分型的诊断符合率,另外随访2年,统计骨折不愈合、股骨头坏死发生率。结果以手术解剖分型、Garden分型为标准,MSCT三维重建技术对股骨颈骨折患者解剖分型、Garden分型诊断相符率分别为98.00%、100.00%,均显著高于X线平片的86.00%、82.00%,差异有统计学意义(P0.05);术后2年死亡1例,失访2例,股骨头坏死、骨折不愈合发生率分别为8.25%、3.09%。结论MSCT三维重建技术相比X线平片在股骨颈骨折解剖分型、Garden分型诊断上有明显优势,可指导手术治疗,减少术后股骨头坏死、骨折不愈合等并发症发生。

Application of Multi-slice Spiral CT Three-dimensional Reconstruction Technique in Femoral Neck Fracture Surgery

Objective To study the application value of multi-slice spiral CT (MSCT) in femoral neck fracture surgery.Methods One hundred patients with femoral neck fractures treated in our hospital between January 2013 and May 2015 were selected as study subjects and were examined by X-ray and MSCT.With surgical results as the golden standard,the coincidence rates were compared between X-ray and MSCT three-dimensional reconstruction technique in the diagnosis of femoral neck fracture anatomic type and Garden type.After 2 years of follow-up,the incidence rates of fracture nonunion and femoral head necrosis were statistically analyzed.Results With surgical anatomic type and Garden type as criteria,the coincidence rates of MSCT three-dimensional reconstruction technique in the diagnosis of anatomic type and Garden type (98.00％ and 100.00％) were significantly higher than those of X-ray films (86.00％ and 82.00％) (P＜0.05).In 2 years after surgery,there were 1 case died and 2 cases lost to followup,and the incidence rates of femoral head necrosis and nonunion were 8.25％ and 3.09％ respectively.Conclusion Compared with X-ray plain film,MSCT three-dimensional reconstruction technique has obvious advantages in the diagnosis of femoral neck ffactureanatomic type and Garden type,which can guide surgical treatment,reduce postoperative femoral head necrosis,nonunion and other complications.
