Etymology
The term "Jefferson fracture" is named after Sir Geoffrey Jefferson (1886–1961), a British neurologist and neurosurgeon who first described the fracture in 1920.
Description
A Jefferson fracture is a complex bone fracture that typically occurs as a result of axial load on the head, such as a diving accident. This fracture is characterized by a burst fracture of the C1 vertebra, leading to a lateral displacement of the lateral masses of C1 on C2. This fracture is unstable and can cause serious complications, including spinal cord injury and death.
