摘要
目的:探析股骨颈股折诊断中多层螺旋CT多平面重建技术的作用效果.方法:回顾性分析2020年1月—2022年4月我院收治的 98例股骨颈骨折患者为研究对象.于术前对患者开展影像学检查,依照检查方法应用的不同划分为A组(n=35)、B组(n=63).A组选用X线检查,B组选用多层螺旋CT平面重建技术.分析不同检查应用的作用效果.结果:A组的诊断符合率为 85.71％,低于B组的 100.00％,差异有统计学意义(P<0.05).在Garden分型方面,B组的Ⅰ型为 20.63％、Ⅱ型 38.10％、Ⅲ型 30.16％、Ⅳ型 11.11％;在骨折分型方面,B组的经颈型 30.16％、头下型 47.62％、基底型 22.22％,诊断符合率均为 100.00％.在血管显影方面,B组中 19例经颈型旋股内外动脉主干显影均清晰,13例支持带动脉清晰显影,6例支持带动脉显影稀疏,同时分布较为扭曲;头下型未发现显影;14例基底型能够清晰可见动脉显影.术后随访发现,A组的股骨头坏死率、骨折愈合延迟或不愈合率分别为25.71％、22.86％,均高于B组的 3.17％、1.59％,组间差异有统计学意义(P<0.05).结论:在临床诊断股骨颈骨折,以及对其分型、评估预后其中,采取多层螺旋CT多平面重建技术,取得的诊断效果明显高于X线片检查,能有效保证检查的开展更具直观性、全面性和准确性,有较好的临床应用价值.
Abstract
Objective:To investigate the effect of multi-slice spiral CT(MSCT)multiplanar reconstruction(MPR)in the diagnosis of femoral neck fracture.Methods:A retrospective analysis of 98 patients with femoral neck fracture admitted to our hospital from January 2020 to April 2022 was performed.According to the application of different examination methods,the patients were divided into group A(n=35)and group B(n=63).X-ray examination was used in group A,and multi-slice spiral CT planar reconstruction technique was used in group B.The effects of different examination applications were analyzed.Results:The diagnostic coincidence rate of group A was 85.71％,which was lower than 100.00％of group B,and the difference was statistically significant(P<0.05).In group B,Garden type Ⅰ was 20.63％,type Ⅱ was 38.10％,type Ⅲ was 30.16％,and type Ⅳ was 11.11％.In terms of fracture classification,in group B,the transcervical type was 30.16％,the subcephalic type was 47.62％,and the basal type was 22.22％,and the diagnostic coincidence rate was 100.00％.In group B,the main arteries of the internal and external circumflex femoral arteries were clearly developed in 19 cases,the retinaculum arteries were clearly developed in 13 cases,and the retinaculum arteries were sparsely developed and distorted in 6 cases.No development was found in the subcephalic type.Arterial development could be clearly seen in 14 cases of basal type.The femoral head necrosis rate and delayed or nonunion rate of fracture in group A were 25.71％and 22.86％,respectively,which were significantly higher than 3.17％and 1.59％in group B(P<0.05).Conclusion:In the clinical diagnosis,classification and prognosis evaluation of femoral neck fractures,the diagnostic effect of multi-slice spiral CT multiplanar reconstruction technology is significantly higher than that of X-ray film examination,which can effectively ensure the development of the examination is more intuitive,comprehensive and accurate,and has good clinical application value.
