There are two main types of incomplete fractures, namely, cleft fractures and green branch fractures, as follows: First, cleft fractures, in which a fracture occurs in the bone cortex without displacement of the fracture end, mostly occur in the skull and scapula, etc. Second, cyanotic fracture, which is mainly prone to occur in pediatric patients. The bone cortical periosteum is partially fractured, and there may be localized angular deformity. In individual cases, the angular deformity is not obvious, and only the bone cortex splits, which is very similar to when a tree branch is broken. The above incomplete fractures mainly include partial interruption of the integrity and continuity of the bone cortex and are classified according to morphology. However, incomplete fractures account for only a small percentage of the fracture types, and most patients have complete fractures. Incomplete fractures heal relatively quickly with aggressive treatment.
