Abstract:
Objective To evaluate the prognostic effects of treatment of giant cell tumor of axis by tumor resection associated with biological reconstruction and internal fixation.Methods From 2009 to 2013,5 patients that had giant cell tumor of axis underwent combined anterior and posterior surgery program.The posterior use pedicle screw system to stabilize the cervical spine,then the anterior use stemocleidomastoid inner edge of the mandibular angle approach to reveal the axis.When the cortex of vertebrae was relatively complete,.When the cortical bone was destroyed,vertebra was resected and the ilium was taken to reconstruct the defect.Adjuvant radiotherapy and diphosphate treatment was used postoperatively.Regular follow-up for X-ray,3D CT and MRI examination were done to observe the tumor recurrence,healing of biological reconstruction and function of cervical vertebra.Results The follow-up time was 12-60 months.No recurrence of the tumor was observed in all patients.The 3 patients accepted beta-TCP implanting after curettage was observed with fuzzy internal structure 3 months after surgery,and the grafted bone fusion can be found 12 months after surgery.The 2 ilium grafted patients can be found with bone fusion with the adjacent vertebrae 6 months after surgery.The bend and stretch function of cervical vertebrae of the 5 patients returned to normal after 3months.The biological healing of bone graft,cervical stability and activity were satisfied.The local pain and neurological symptoms were relieved.Conclusion Anterior and posterior surgery program in combination with biological reconstruction and adjuvant radiotherapy provide an excellent option for treatment of giant cell tumor of axis.The dens could be retained to keep the function of occipital cervical when the odontoid bone cortex is not destructed.
