Goniometric measurement of shoulder range of motion (ROM) was performed,as well as functional evaluation using the rating scale shoulder of the University of California (UCLA), the Constantscale, score of disability of the arm, shoulder and hand (DASH) and visual analog scale (VAS). Postoperativecomplications, implants removal rates and new x-rays were analized.Results: The mean postoperative follow-up was 41.5 (24; 69. SD 13.4) months. Mean shoulder anterior elevationwas 168.5º (120; 180. SD 22.9). The average value obtained for abduction was 175.2° (150; 180. SD 27.8), as tointernal and external rotations, these were not affected. DASH 1.27% (0%; 25%. SD 4.3), UCLA 33.6 points (20;35. SD 3.5), Constant 90.5 points (50; 100. SD 11.2) and VAS was 0 in 34 patients (83%). Complications: mildresidual pain (3), hypoesthesia of the infraclavicular area (2), and rupture (1) and loosening (1) of the implant.hardware removal due to intolerance (2 cases) and new osteosynthesis due to acute implant rupture (1 case).Conclusion: Our experience after a mean follow-up of 41.5 months with precontoured locking plates for the treatmentof displaced mid-shaft clavicle fractures has shown good functional results, with low complication and reoperationrate.Level of evidence: IV}, keywords = {Clavicle,Complications,Fractures,Hardware Removal,Osteosynthesis,outcomes,Plates}, url = {https://abjs.mums.ac.ir/article_10828.html}, eprint = {https://abjs.mums.ac.ir/article_10828_a7c8cf4567545b0f43a63ec2883b426c.pdf} }
