Meta-analysis of the incidence of degeneration of surgically adjacent segments after artificial cervical disc replacement in mainland China
To understand the incidence of postoperative segmental degeneration adjacent to surgery after artificial cervical disc replacement (ACDR) in mainland China.
A systematic search of the published literature from January 1997 to October 2016. The search databases included Chinese Biomedical Literature Database, CHKD full-text journal database, Wipu Chinese Science and Technology Journal Database, Wanfang Medical Journal Database, pubmed database, OVID platform database, Cochrane library database and Embase database. Retrieved October 2016 . Studies reporting the incidence of surgical adjacent segment degeneration after ACDR were included, relevant information was extracted, and the data were subjected to Meta-analysis using Stata 12.0 software.
A total of 20 articles were included in the literature. The weighted combined ACDR incidence of surgical adjacent segment degeneration was 0.4% at 24 months postoperatively and 29.0% at 72 months postoperatively.
The incidence of surgically adjacent segmental degeneration after ACDR in mainland China is low in the short term but high in the distant postoperative period.
