Abstract: Objective The purpose of this study was to explore the advantages of coordinate precise positioning small incision rib fracture internal fixation and traditional rib fracture internal fixation in clinical practice. Methods Forty patients with rib fracture were randomly divided into coordinate group and control group from March 2015 to December 2017. Eighteen patients in coordinate group and 22 patients in control group were enrolled in the study. postoperative complications，time of hospitalization and pain scores of 5 days after operation，the operation time，the length of incision，the amount of blood loss，the length of drainage tubewere compared between the two groups. Results The VAS scores of the two groups within 5 days after operation ，The scores were gradually reduced ，using the oneway general linear regression analysis of variance，F=34.689，P=0.000，there were statistical differences. There was no significant difference in the complications between the two groups （χ2=0.058，P=0.598）. There was no significant difference in the blood loss between the coordinate group and the control group（58±36 mL， 83+ 48 mL，t=1.83，P=0.058）. The operation time of the two groups was 53± 11 min in the coordinate group，and 87±24 min in the control group（t=5.51，P=0.010）. The incision sizes of the two groups were7.5±1.4 cm ，11.9±2.3 cm ，t=7.02 ，P=0.002 ，respectively. There was a statistical difference in theindwelling time of the wound drainage tube，t=6.32，P=0.003. There was no statistical difference in the VAS scores of the two groups before operation in terms of pain sensation. Conclusion The application of internal fixation with precise coordinate positioning for rib fracture through small incision has the advantages of less pain，faster recovery and better surgical effect than general internal fixation.
