Which type of fracture occurs when a vertebra has been crushed in all directions?

A burst fracture occurs when a vertebra is crushed in multiple directions, causing the bony structure to fragment in various ways. This type of fracture typically results from significant trauma, such as a fall from a height or a severe automobile accident. The defining characteristic of a burst fracture is the vertebra being compressed axially and breaking apart due to the immense pressure, which can lead to fragments that may impinge on surrounding structures, including the spinal canal. This distinction is critical as it highlights the potential complications and urgency in management that can arise from such fractures. Understanding this can be essential for accurate coding and appropriate treatment planning in a clinical setting.
