Purpose
The aim of this study was to compare the efficacy and safety of anterior cervical discectomy and fusion (ACDF) and cervical arthroplasty for patients with cervical spondylosis.
Methods
PubMed, Embase, and Cochrane Library were used to search for relevant articles published prior to April 2016 to identify studies comparing ACDF and cervical arthroplasty involving patients with cervical spondylosis. Relative risks (RR) and mean differences (MD) were used to measure the efficacy and safety of ACDF and cervical arthroplasty using the random effects model.
Results
The meta-analysis of 17 studies involved 3122 patients diagnosed with cervical spondylosis. Patients undergoing ACDF showed lower overall success rate (RR 0.84; 95 % CI 0.77–0.92; P < 0.001), higher VAS score (MD 0.36; 95 % CI 0.08–0.64; P = 0.011), and shorter mean surgical duration (MD −1.62; 95 % CI −2.80 to −0.44; P = 0.007) when compared with cervical arthroplasty. However, the association between ACDF therapy and the risk of mean blood loss (MD −0.16; 95 % CI −0.34 to 0.02; P = 0.082), mean hospitalization (MD 0.02; 95 % CI −0.31 to 0.36; P = 0.901), patient satisfaction (RR 0.96; 95 % CI 0.92–1.00; P = 0.066), neck disability index (MD 0.20; 95 % CI −0.05 to 0.44; P = 0.113), reoperation (RR 1.25; 95 % CI 0.64–2.41; P = 0.514), or complication (RR 1.17; 95 % CI 0.90–1.52; P = 0.242) was not statistically significant.
Conclusions
Patients undergoing ACDF therapy tended to exhibit lower overall success rate, higher VAS score, and decreased mean surgical duration when compared with patients treated with cervical arthroplasty.
