[Clinical outcome of mid-term follow-up of anterior cervical non-fusion surgery versus anterior cervical discectomy and fusion for cervical spondylosis].

Two cervical non-fusion surgery and ACDF have received good clinical effects in the treatment of spondylotic myelopathy or radicular spondylosis.The artificial cervical disc replacement and dynamic cervical implant can not only recover cervical lordosis and keep the range of motion and stability of the surgical segment, but also reduce the incidence of compensatory motion at adjacent segments and will prevent from adjacent segment degeneration.
