Abstract: Objective To compare the accuracy and surgical effect of ultrasound and CT guided rib fracture incision and reduction of internal fixation. Methods A total of 185 patients with chest trauma with multiple rib fractures admitted to the Department of Cardiothoracic Surgery Ningde Hospital affiliated to Ningde Normal University from January 2019 to December 2021 were collected.They were divided into control groups and observation groups according to different positioning methods.The control group performed routine CT reconstruction to determine the surgical incision.The observation group determined the surgical incision by high-frequency ultrasound.Patients in both groups underwent conventional incision reduction and internal fixation surgery.The incision accuracy,surgery-related indicators,VAS score and the overall treatment effect score were compared between the two groups.Results The Incision accuracy was 93.06% in the observation group and 88.37% in the control group,which was statistically significant(P<0.05).Observation group fracture exposure time(19.95±4.98)min,operation time(52.78±8.19)min,fracture healing time(43.70±3.21)d,drainage ball placement time(3.89±1.38)d,In the control group,the exposure time of fracture(28.47±5.64)min,operation time(65.61±10.72)min,fracture healing time(46.61±2.32)d and drainage ball placement time(5.17±2.01)d were statistically significant(P<0.05).VAS scores(4.72±1.67),GI scores(1.78±0.34),EI scores(1.23±0.32) in observation group 3 days after surgery,VAS scores(6.72±2.01),GI scores(2.61±0.45),EI scores(0.03±0.25) in control group 3 days after surgery,There was statistically significant(P<0.05).Conclusion As for rib fracture incision and reduction of internal fixation,Ultround-guided localization is better than CT and overall surgical treatment with ultrasound localization is better than CT.

Key words: rib fracture incision and reduction of internal fixation, three-dimensional CT reconstruction, high-frequency ultrasound localization, and incision accuracy
