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.

摘要： 目的 本研究旨在探索坐标精准定位小切口肋骨骨折内固定术与常规肋骨骨折内固定术方法的在临床实践中的优势。方法 选取我科自 2015 年 3 月至 2017 年 12 月期间进行肋骨骨折手术治疗患者共 40 例，随机分为坐标组及对照组，坐标组 18 人，对照组 22 人，比较两组患者在术后 5 天疼痛评分变化，手术时间，手术切口长度、失血量，伤口引流管带管天数，术后并发症例数、住院时间方面的差异。结果 在患者疼痛感觉方面，两组患者在手术前的VAS 评分无统计学差异，5 日内的 VAS 评分随着时间的推移，评分均逐渐降低，使用单因素单因素方差分析，F=34.689，P=0.000，有统计学差异，两组在并发症方面无统计学意义（χ2=0.058，P=0.598），在失血量方面坐标组 58±36 mL，对照组 83±48 mL，t=1.83，P=0.058，无统计学差异，两组患者手术时间坐标组 53±11 min，对照组 87±24 min，两组有统计学差异，t=5.51，P=0.010，切口大小方面比较两组患者切口大小分别为 7.5±1.4 cm ，11.9±2.3 cm ，t=7.02 ，P=0.002 ，有统计学差异，伤口引流管留置时间方面，有统计学差异 t=6.32 ，P=0.003 。结论 坐标精准定位小切口肋骨骨折内固定的应用，患者的痛苦小、恢复快、手术效果明显优于传统内常规固定手术。
