DTS在胫骨骨折内固定术后的应用价值OACSTPCD

Objective To investigate the application value of digital tomosynthesis(DTS)in the review of tibial fracture after internal fixation.Methods A total of 120 cases of tibial fracture patients who underwent fixation surgery in our hospital from October 2020 to October 2023 were examined by digital radiography(DR)and DTS at 3 and 6 months after operation.The image quality and fracture healing display of the two imaging methods were compared,and the consistency of the image quality scores of the two doctors were evaluated.Results The two doctors showed good consistency in the image quality scores of DTS and DR.At 3 months after operation,the DTS image quality score was(3.658±1.170)and the DR image quality score was(2.750±1.176),with a statistically significant difference between the two groups(P<0.05).The display rate of fracture healing on DTS images was 91.67%(110/120),while the display rate of fracture healing on DR images was 72.50%(87/120),with a statistically significant difference(P<0.05).At 6 months after operation,the DTS image quality score was(3.692±1.165)and the DR image quality score was(2.792±1.187),with a statistically significant difference between the two groups(P<0.05).The display rate of fracture healing on DTS images was 93.33%(112/120),while the display rate of fracture healing on DR images was 75.83%(91/120),with a statistically significant difference(P<0.05).Conclusion In the follow-up examination of tibial fractures after internal fixation,the image quality of DTS is better than that of DR,which can more clearly display the bone structure and fracture healing situation in the operative area.It helps clinicians to evaluate the recovery after internal fixation more accurately and has a high clinical application prospect.
