Which statement describes the characteristics of a Jefferson fracture?

• A. Fracture of the pedicles of the axis with neuro symptoms
• B. Burst fracture of C1 with possible absence of neuro symptoms
• C. Fracture in the middle to lower cervical spine
• D. Fracture of C2 with neuro compromise

Answer: (B)

A Jefferson fracture is specifically characterized as a burst fracture of the first cervical vertebra (C1), which is known for its unique ring-like structure. This type of fracture typically occurs from axial loading, such as during a diving accident or a fall onto the head. One of the key features of the Jefferson fracture is that it can occur without neurovascular compromise, which aligns with the selected statement. In the context of identifying a Jefferson fracture, it's essential to consider the anatomical implications. The bursting nature of this fracture means that the bony ring of C1 is disrupted, but because of its location and the protective surrounding structures, it doesn't always lead to immediate neurological deficits. Therefore, statement B accurately reflects the characteristics of a Jefferson fracture by highlighting that while it is a burst fracture of C1, it may not result in neurological symptoms. The other options address different types of fractures or anatomical locations, which do not accurately convey the distinct nature of a Jefferson fracture. These mistakes could lead to misdiagnosis or misunderstanding of related cervical spine trauma.
