Abstract

Background: The aim of this study was to evaluate functional outcome and complications with a long term follow
up (minimum of 2 years post-operative) in patients with mid-shaft clavicle fractures treated with precontoured locking
plates.
Methods: We included 41 patients. 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 Constant
scale, score of disability of the arm, shoulder and hand (DASH) and visual analog scale (VAS). Postoperative
complications, 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 elevation
was 168.5º (120; 180. SD 22.9). The average value obtained for abduction was 175.2° (150; 180. SD 27.8), as to
internal 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: mild
residual 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 treatment
of displaced mid-shaft clavicle fractures has shown good functional results, with low complication and reoperation
rate.
