1. Fractures are classified based on their severity, shape or position of the fracture line or the physician who first described them.
2. Types of fractures:
1. Open fractures: The broken ends of the bone protrude through skin.
2. Comminuted fractures: The bone is splintered, crushed or broken into pieces at the site of impact and smaller bone fragments lie between the two main fragments.
3. Greenstick fractures: A partial fracture in which one side of the bone is broken and the other side bends.
4. Impacted fractures: One end of the fractured bone is forcefully driven into the inferior of the other.
5. Pott fractures: Fracture of the distal end lateral leg bone with serious injury of the distal tibial articulation.
6. Codes fractures: Fracture of the distal end of the lateral forearm in which the distal fragment is displaced posteriorly.
3. A fractured bone heals in four phases viz, reactive phase, fibrocartilaginous formation phase, bony callus formation phase and bone remodeling phase.
