Does cervical disc arthroplasty reduce adjacent segment disease and other complications in comparison to anterior cervical discectomy and fusion? A meta-analysis of randomized controlled trials

Abstract

Concurrent Session 5A - Cervical Spine: paper no. 72SUMMARY: A meta-analysis of the literature was performed to assess the development of adjacent segment degeneration/disease between cervical disc arthroplasty (CDA) to that of anterior cervical discectomy and fusion (ACDF) at 2 and 4 year follow-up periods. Due to weaknesses in study design, heterogeneity in management, and relatively high withdrawal/drop-out rates, robust conclusions supporting the advocacy of CDA over ACDF cannot be made at this ...postprin
