Objective: Dysphagia is a common occurrence after anterior cervical spine surgery. The aim of this meta-analysis was to evaluate the incidence of dysphagia after ervical disc arthroplasty (CDA) compared with anterior cervical discectomy and fusion (ACDF).
Material And Methods: The electronic databases, including PubMed, EMBASE and Cochrane Central Register of Controlled Trials, were searched to identify the randomized controlled trials comparing CDA with ACDF.
Background: Anterior cervical discectomy and fusion is a standard surgical treatment for cervical radiculopathy and myelopathy, but reoperations sometimes are performed to treat complications of fusion such as pseudarthrosis and adjacent-segment degeneration. A cervical disc arthroplasty is designed to preserve motion and avoid the shortcomings of fusion. Available evidence suggests that a cervical disc arthroplasty can provide pain relief and functional improvements similar or superior to an anterior cervical discectomy and fusion.
