Objective: The aim of this study was to evaluate and compare the biomechanical effects of locking plate superior and anteroinferior positioning on the osteosynthesis of the clavicles osteotomized obliquely. Materials and methods: Ten matched pairs of fresh cadaveric clavicles osteotomized through the mid-shaft obliquely were repaired with a titanium 7-hole 3.5-mm reconstruction locking plate in the superior or the anteroinferior position. The maximal failure loads and the displacement of the specimens at 166 N, 183 N, 203 N loads were recorded by the machine in 3-point cantilever bending. Bending failure stiffness was calculated between 10–150 N and 151 N to maximal bending failure loads. Results: The mean maximal failure load was 396.2 N (SD, 117.3) for superior constructs and 220.1 N (SD, 51.1) for anteroinferior one (P
