Author(s):

Dixon D, Le ME, Caputo A and Darden B

Background: Adjacent segment degeneration (ASD) occurs after anterior cervical discectomy and fusion (ACDF) at a rate of 2.9% per level per year. Cervical disc arthroplasty was developed to theoretically reduce the transfer of forces onto adjacent levels while allowing motion at adjacent sites. We present a review of the biomechanics of cervical disc arthroplasty. Methods: A systematic review of the literature was performed by three junior authors regarding the biomechanics and/or the alteration of the biomechanics following a cervical disc arthroplasty. PubMed and Medline databases were used. Keywords for search results utilized included; cervical disc arthroplasty, adjacent segment disease, cervical disc biomechanics, cervical arthroplasty biomechanics. Level IV evidence or higher was... view more»
