3D Model of Fracture of Dens of Cervical Vertebra 2 (C2), Type 2a (Anderson and D'Alonzo Classification)

Focusing on a Type 2a dens fracture of the second cervical vertebra (C2), this 3D model illustrates a variant of the classic Type 2 injury with minimal displacement and intact transverse ligament. Classified by Anderson and D'Alonzo, this fracture occurs at the base of the odontoid process and typically carries a better prognosis due to its relative stability. The model provides a clear anatomical view to support education on cervical trauma and fracture management.
