21. Radiographic predictors of subaxial subluxation after atlantoaxial fusion
The incidence of atlantoaxial fusion for atlantoaxial instability (AAI) has been increasing. Subaxial subluxation (SAS) can develop after surgery despite atlantoaxial fusion with the optimal C1-C2 angle. We hypothesized that preoperative discordant angular contribution in the upper and subaxial cervical spine is associated with the occurrence of postoperative SAS.
