Influence of the T1-slope on sagittal alignment of the subaxial cervical spine after posterior atlantoaxial fusion in os odontoideum

Posterior atlantoaxial fusion has been greatly used in the treatment of atlantoaxial dislocation or instability, achieving good clinical results. However, it sacrifices the motion of atlantoaxial articulation. Secondary postoperative loss of cervical lordosis, even cervical kyphosis is observed in some cases, leading to neck pain and recurrence or deterioration of neurological deficits [1 –6]. C1-C2 fixation angle is considered to be an important factor influencing postoperative alignment of the subaxial cervical spine in previous studies.
