Application of Digital Tomosynthesis in Postoperative Internal Fixation of Femoral Shaft Fractures
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.
