摘　　要：目的探讨数字断层融合摄影(DTS)在股骨干骨折内固定术后复查中的应用价值。方法收集90例股骨干骨折内固定术后患者,于术后6月时完成了数字化X线摄影(DR)及DTS检查。由两名放射科医师采用5分法对两种影像学检查方法所获图像进行图像质量评价及对比。同时由临床医师对DTS及DR的骨折愈合显示率进行对比。结果术后6月时,DTS图像质量评分为(3.689±1.148)分,DR图像质量评分为(2.778±1.197)分,两组差异具有统计学意义(P<0.05)。DTS图像骨折愈合情况显示率为95.56%(86/90),DR图像骨折愈合情况显示率为72.23%(65/90),差异具有统计学意义(P<0.05)。结论在股骨干骨折内固定术后复查中,DTS能清晰显示术区骨质结构,准确判断骨折愈合情况,图像质量较DR更优,可作为股骨干骨折内固定术后复查较为理想的影像学检查方法,临床实用性较强。Objective Exploring the application value of digital tomosynthesis(DTS)in postoperative review of femoral shaft fracture after internal fixation.Methods Collect 90 patients with femoral shaft fractures who underwent internal fixation surgery and complete digital radiography(DR)and DTS examinations at 6 months after surgery.Two radiologists evaluated and compared the image quality obtained by two imaging examination methods using the 5-point method.At the same time the fracture healing display rate of DTS and DR was compared by clinicians.Results 6 months after surgery,the DTS image quality score was(3.689±1.148)points,and the DR Image quality score was(2.778±1.197)points,with a statistically significant difference between the two groups(P<0.05).The display rate of fracture healing on DTS images was 95.56%(86/90),while the display rate of fracture healing on DR images was 72.23%(65/90),with a statistically significant difference(P<0.05).Conclusion In the postoperative follow-up of femoral shaft fracture internal fixation,DTS can clearly display the bone structure of the operative area and accurately judge the fracture healing,and the image quality is better than DR,which can be used as an ideal imaging examination method for the review after internal fixation of femoral shaft fracture,and has strong clinical practicability.
