The odontoid process tilting angle (OPTA) was used to evaluate fracture reduction.

Three patients underwent anterior release and posterior fixation surgery, and the other 4 underwent posterior-only surgery. The fixation segment was C1 to C2. The average follow-up period was 34.7 \u00b1 8.5\u00a0months. The average operation time was 145.7 \u00b1 45.3\u00a0min, with an average blood loss volume of 95.7 \u00b1 33.3\u00a0mL. The OPTA was corrected from 41.9\u00b0 \u00b1 11.1\u00b0 preoperative to 2.4\u00b0 \u00b1 3.2\u00b0 at the final follow-up ( P &lt; .05). The preoperative Frankel grade of 1 patient was grade C, of 2 patients was grade D, and of 4 patients was grade E. The neurological function of the patients in grade C and grade D recovered to grade E at the final follow-up. None of the patients developed a complication. All the patients achieved odontoid fracture healing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
