This 1997 narrative review by Chutkan et al covers the evaluation and management of odontoid fractures, using the Anderson and d'Alonzo classification to organize diagnostic workup, nonunion risk factors, and treatment algorithms for each fracture type in both adult and pediatric patients.
When you encounter an odontoid fracture, displacement is your key decision variable: Type II fractures displaced >4–5 mm warrant operative planning (anterior screw fixation if no ligament rupture, comminution, or oblique fracture pattern; otherwise posterior arthrodesis), while nondisplaced Type II and all Type III fractures can be trialed in halo immobilization with close radiographic follow-up.
Always obtain MRI to rule out transverse ligament rupture in Type II fractures — if present, anterior screw fixation alone will leave atlantoaxial instability even after the odontoid heals.
