Abstract

Objective To explore the clinical efficacy of bone grafting in the treatment of type Ⅱ odontoid fracture with pedicle screw fixation. Methods Of 14 cases with type Ⅱ odontoid fractures, 8 patients in group A received pedicle screw, lamina autologous bone grafts, 6 cases of group B received simple posterior pedicle screw fixation.The operative time, the amount of surgical bleeding and the postoperative cervical spine flexion and rotation were observed at 3 months postoperatively, and the patients were followed up for 5-45 months. Results All patients were followed up for 5-45 months, with an average of 26.5 months.The operation time was (1.83±0.5)h in the bone graft group, and (1.58±0.9)h in the non-bone graft group, the difference was statistically significant (t=2.842, P>0.05). The blood loss of the bone graft group was (150±16)mL, which of the non-bone graft group was (120±14)mL, the difference between the two groups was statistically significant (t=3.57, P>0.05). After 3 months, the flexion of the cervical spine of the bone graft group was (31.2±4.6)°, which in the non-grafted group was (32.3±5.7)°, the difference was statistically significant (t=0.675, P<0.05). The rotation of the bone graft group was (40.6±4.5)°, which in the non-graft group was (41.3±3.5)°, the difference was statistically significant (t=0.278, P<0.05). Both two groups had no vertebral artery and spinal cord injury, wound healing.During the follow-up period, the two groups of patients had a good reduction of cervical spine, no internal fixation lossening, fracture, fracture healing well, group A bone graft fusion. Conclusion For this type of fracture, simple atlantoaxial pedicle screw fixation compared with autologous iliac bone graft fusion treatment, can save the operation time, reduce the amount of bleeding.
