osteogenesis (or ossification) is that the method of parturition down new bone material by cells known as osteoblasts. It's synonymous with bone tissue formation. There are 2 processes leading to the formation of traditional, healthy bone tissue: Intramembranous ossification is that the direct parturition down of bone into the primitive animal tissue (mesenchyme), whereas endochondral ossification involves animal tissue as a precursor in it. Endochondral osteogenesis in fracture healing is that the most typically occurring method, as an example in fractures of long bones treated by plaster of Paris which is a material, whereas fractures treated by open reduction and stabilization by metal plate and screws could heal by intramembranous osteogenesis. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed
