Abstract:
BACKGROUND:The two main cages used in anterior cervical surgery are titanium cages and poly(ether-ether-ketone) cages, but it is stil controversial in imaging performances and clinical outcomes.
OBJECTIVE:To systematical y evaluate imaging performances and clinical outcomes between titanium cages and poly(ether-ether-ketone) cages in anterior cervical discectomy and fusion surgery.
METHODS:The Cochrane library (issue 5, 2013), Medline database, EMBASE, CNKI and Wanfang database were retrieved by computer. The deadline of al the retrieves concerning control study of uses of titanium cages and poly(ether-ether-ketone) cages was June 1st, 2013. Two reviewers assessed literatures independently, and the meta-analysis was conducted by RevMan 5.2 software.
RESULTS AND CONCLUSION:A total of four literatures including 235 patients, 128 of titanium cages and 107 of poly(ether-ether-ketone) cages, were included. Meta-analysis results showed that there was no statistical y significant difference between the groups in fusion rates, subsidence and dislocation rates of short-term fol ow-up and clinical outcomes (al P>0.05). There were statistical y significant differences between the groups in subsidence and dislocation rates of long-term fol ow-up (P<0.05). Poly(ether-ether-ketone) cage group was superior to titanium cages group in maintenance of cervical curvature and intervertebral height. This meta-analysis showed that poly(ether-ether-ketone) cages had good fusion rates and clinical outcomes, less subsidence and dislocation rates, and can better maintain cervical curvature and intervertebral height compared with titanium cages.
