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 rotationwere 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 .
