Clinical Application of Computer-aided Design-Rapid Prototyping in C1–C2 Operation Techniques for Complex Atlantoaxial Instability

Study Design: This is a retrospective clinical study. Objective: To evaluate the clinical efficacy of computer-aided design-rapid prototyping (CAD-RP) techniques in surgical treatments for atlantoaxial instability (AAI). Summary of Background Data: The complexity of the upper cervical anatomic structures makes the procedures for the treatment of AAI particularly challenging for surgeons. The present study represents a series of C1–C2 surgery for...
