Jefferson fracture

Mechanism and manifestations

A fall or impact to the head can cause upper neck pain. Absence of paralysis does not establish stability; several fracture lines may involve the C1 arches.

Diagnosis and management

CT defines the fractures, and MRI may assess ligaments. Immobilization and specialist evaluation take priority; bracing or surgery depends on displacement and stability. Manipulation or comfort-oriented traction is inappropriate before medical clearance.

Points to consider

After trauma, pain intensity and injury severity are not always proportional. Mechanism, level, neurological status and stability guide care. New weakness, sensory loss, breathing difficulty or impaired walking requires urgent assessment.

Role of TAGMED care

With acute symptoms, urgent hospital assessment takes priority. This condition first requires medical diagnosis and, depending on the situation, specialist management. TAGMED services do not replace treatment of infection or tumor, stabilization of an unstable injury, or neurological or vascular treatment. Any conservative support should be considered only after diagnosis, restrictions and the treating team’s recommendations have been clarified.

Related concepts and distinctions

These concepts belong to the same field, but are not synonyms.

• Odontoid fracture — Fracture of the axis dens, classified partly by fracture location and potentially compromising upper cervical stability.
• Hangman fracture — Bilateral fracture through the C2 pars region, sometimes associated with C2–C3 displacement and disc-ligament injury.
• Cervical teardrop fracture — Cervical fracture with a teardrop-shaped anteroinferior bone fragment, occurring through different mechanisms with variable stability.
