We aimed at proposing a classification with treatment algorithm of each category for CMFs. Patients with CMFs were retrospectively reviewed and classified into five categories: Type I: relatively good occlusion, no or slightly displaced fragments, no continuity destruction or bone defect; Type II: relatively good occlusion, damaged morphology, low comminution degree but intact continuity without bone defect; Type III: damaged morphology and higher comminution degree with intact continuity and relatively good occlusion; Type IV: high comminution, impaired continuity and poor occlusion without segmental bone defect; Type V: segmental bone defect.
