High energy clavicle shaft fractures consistently occur at the inflection point: defining morphology and correlation with fracture patterns

Background: Midshaft clavicle fractures are the most common subtype of clavicle injuries, yet the morphologic basis for their consistent location remains unclear. This study aims to define the anatomical inflection point of the clavicle and investigate its correlation with fracture location, hypothesizing that most high-energy midshaft fractures occur at this morphologically consistent point of curvature transition. Methods: -tests, and nonparametric tests. Results: < .05). No significant difference in fracture location was observed by gender or laterality. Conclusion: High-energy clavicle fractures consistently occur at the anatomical inflection point, a morphometrically distinct region where curvature transitions from medial to lateral. Recognition of this consistent fracture location may improve surgical planning, implant design, and biomechanical modeling.
