Anterior cervical stabilization using a semi-constrained cervical plate and titanium mesh cage for single level corpectomy.
Journal of Clinical Neuroscience(2008)
摘要
In this study we reviewed the treatment outcomes for 20 consecutive patients who underwent anterior 1-level cervical corpectomy and reconstruction using a titanium mesh cage and semi-constrained plating after an average follow-up of 14.8 months. Two groups, each of 10 patients, underwent surgery with 10-mm and 13-mm diameter cages, respectively. Bony fusion and the radiological outcome were evaluated using follow-up radiography and sagittal reconstructed CT scans. The radiographs revealed bony consolidation in 95% of the 20 patients during follow-up. Five cases of construct failure occurred after surgery:1 failure (10%) was encountered in the 10-mm cage group and 4 (40%) occurred in the 13-mm cage group (P=0.085). The failures were mainly the result of cage settling and screw-plate failure. Although the clinical outcomes and fusion rates for anterior cervical stabilization using a semi-constrained plate and titanium cage were favorable, further biomechanical evaluations and a prospective randomized study will be necessary to fully understand this dependence of implant failure on cage size.
