ABSTRACT：ObjectiveTocompare thesmile incision combined with indirect reduction technique with traditional ORIFtechnique andsystematicall evaluate theadvantages of this innovativesurgicalmethodin terms offunctionalrecovery and postoperative cosmetic efects.MethodsA total of 6Opatients with midshaft clavicle fractures were enroled betwen October 2022 and August 2O24.The patients were randomly asigned to either ORIF group（open reduction and internal fixation， n=30 ）orMIPPO group （MIPPO combined with smile incision， n=30） .Outcomes assessed included surgical trauma，functional recovery，and cosmetic outcomes.ResultsThe MIPPO group exhibited significantlyreduced intraoperative blood loss [（32.9±7.6）mL VS. （90.2±14.0）mL ， P<0.05] ，shorterincision length .（8. （204号 5±1.2）cm ， P<0.05] ，and reduced operative time compared to the ORIF group.Functional recovery indicators such as bone healing time weeks vs. （12.8±2.0） weeks， P<0.05] ，initial and complete self-care time，and weight-bearing recovery were allsignificantly improved in the MIPPO group.The Constant-Murleyscore was higher in the MIPPO group （91.5±5.1 vs. 82.4±6.0 ， P<0.05） .Cosmetic outcomes also favored the MIPPO group，with a superior SBSES score （9.2±0.4νs.3.0±0.7 ， ）and better results in scar visibility，pigmentation，thickness， and elasticity.ConclusionThe smile incision combined with indirect reduction technique significantly reduces surgical trauma，acelerates postoperative recovery，and provides substantiallybetter cosmetic outcomes compared to conventional methods，making it particularly suitable for patients with high aesthetic expectations.

锁骨骨折是临床常见损伤1，传统切开复位内固定（open reductionand internal fixation，ORIF）术后常遗留明显瘢痕、组织损伤较大[2]，患者术后恢复较慢、满意度低[3-4]，而传统微创技术（如minimallyinvasiveplateosteosynthesis，MIPPO）则因复位困难、切口设计不合理，应用受限[5-7]。（剩余9067字）
