| Abstract |
Objective: Reconstruction and stabilization of the cervical spine after corpectomy including tumor resection is a princi- pal goal in the surgical treatment of cervical spinal metastasis. This study is aimed to describe the clinical outcome and the surgical technique using a titanium mesh cage filled with polymethylmethacrylate(PMMA) augmented by an- terior cervical plating and screw fixation.
Methods: Eleven patients ranging from 36 to 71 years of age underwent anterior tumor resection, corpectomy, inser- tion of a titanium mesh cage already filled with PMMA, and anterior plating and screw fixation. The clinical outcome, survival, complication, and radiological outcome were assessed retrospectively.
Results: All 11 patients showed motor improvement and experienced significant palliation of biomechanical neck pain. All patients achieved immediate stabilization, restoration of the height of vertebral body and normal lordosis. Additional posterior instrumentation was not performed in any patients. There were no complications such as neurological wor- sening, postoperative hematoma, wound infection, subsidence, or graft dislodgement except one construct failure during a follow-up period of 3 to 33 months(mean 12 months). Overall mean survival was 15.4 months for 11 patients and the median survival was 15.0 months. One year survival rate was 50.5%.
Conclusion: Titanium mesh cage already filled with PMMA, augmented by anterior cervical plating and screw fixation is an effective method in treating patient with cervical spinal metastasis. |
