Review Meta Analysis Comparative Study
Determining the difference in clinical and radiological outcomes between expandable and non-expandable titanium cages in the cervical fusion procedures: A Systematic Review and Meta-Analysis.
Expandable cages have been increasingly used in cervical and lumbar reconstructions; however, there is a paucity in the literature on how they compare with traditional nonexpandable cages in the cervical spine. We present a systematic review and meta-analysis, comparing the clinical and radiologic outcomes of expandable versus nonexpandable corpectomy cage use in the cervical spine. ⋯ The use of expandable cages may carry a modest improvement in radiologic outcomes compared with nonexpandable cages in the cervical spine; however, they may also lead to a higher rate of revisions based on our analyses.
