Evensson

Evensson is a relatively rare type of fracture that affects the vertebrae of the spine, particularly in the thoracic region. It is characterized by a compression fracture or a burst fracture resulting in a fissure or a crack in the posterior elements of the vertebrae.

The term "Evenson" was first used to describe this type of fracture by surgeon William T. Evenston in the early 20th century. However, it is now widely accepted that this fracture type is more commonly associated with the work of another surgeon, Axel Lindahl.

Evensson fractures usually occur due to a traumatic injury, such as a fall from a significant height or a high-speed collision. The fracture typically results from a combination of forces, including compression, distraction, and rotation. These fractures can be either a low-energy or high-energy event, depending on the individual circumstances.

Diagnosis of an Evenson fracture is often straightforward, with plain radiographs (X-rays) revealing the characteristic fracture pattern. However, in some cases, further imaging, such as computed tomography (CT) or magnetic resonance imaging (MRI), may be required to fully appreciate the extent of the injury.

The treatment for Evenson fractures typically involves stabilization with either a spinal cast or surgical hardware, depending on the severity of the fracture and the individual patient's needs. Rehabilitation and physical therapy often follow to address any residual discomfort or limitations.

While Evenson fractures are relatively uncommon, prompt and proper diagnosis and treatment are essential for optimal outcomes.
