X线和螺旋CT在桡骨远端骨折诊断中的应用价值比较

Comparison of the Value of X-ray and Spiral CT in the Diagnosis of Distal Radius Fractures

目的分析X线和螺旋CT在桡骨远端骨折诊断中价值。方法选取2017年3月—2019年12月我院疑似桡骨远端骨折患者78例,分别接受X线诊断,螺旋CT诊断,患者均通过术后分析确诊桡骨远端骨折73例。结果CT诊断时关节面分离程度(6.28±0.87)mm、关节面压缩程度(7.58±1.24)mm高于X线关节面分离程度(2.84±1.04)mm、关节面压缩程度(3.62±1.17)mm,差异有统计学意义(t=15.844、14.506,P<0.05);CT诊断时关节面粉碎性骨块、关节面压缩塌陷以及关节面分离等发生机率更高,差异有统计学意义(P<0.05);两组患者掌倾角改变以及尺偏角改变评分差异无统计学意义(P>0.05);CT患者诊断时检测符合率、灵敏度,特异度,漏诊率更低,差异有统计学意义(χ^(2)=4.982、4.692、5.241、5.811,P<0.05)。结论螺旋CT在桡骨远端骨折诊断可分析关节面压缩程度和分离程度,同时并诊断灵敏度和符合率也较高,可有效诊断疾病损伤严重程度,有临床应用价值。

Objective To analyze the value of X-ray and spiral CT in the diagnosis of distal radius fracture.Methods 78 patients with suspected distal radius fractures in our hospital from March 2017 to December 2019 were diagnosed by X-ray and spiral CT respectively.73 patients with distal radius fractures were confirmed by postoperative analysis.Results The degree of articular surface separation(6.28±0.87)mm and articular surface compression(7.58±1.24)mm in CT diagnosis were higher than that in X-ray(2.84±1.04)mm and(3.62±1.17)mm(t=15.844,14.506,P<0.05).In CT diagnosis,the incidence of articular flour broken bone mass,articular surface compression collapse and articular surface separation was higher,the difference was statistically significant(P<0.05).There was no significant difference in the scores of palmar inclination and ulnar deviation between the two groups(P>0.05).The coincidence rate,sensitivity,specificity and missed diagnosis rate of CT diagnosis were lower,and the difference was statistically significant(χ^(2)=4.982,4.692,5.241,5.811,P<0.05).Conclusion Spiral CT can analyze the degree of articular surface compression and separation in the diagnosis of distal radius fracture.At the same time,it has high diagnostic sensitivity and coincidence rate.It can effectively diagnose the severity of disease injury and has clinical application value.
