The current standard of care for cervical myopathy is anterior discectomy and fusion (ACDF). Although well tolerated in the short term, this treatment might ultimately result progressive degeneration adjacent motion segments. Artificial disc arthroplasty offers theoretical advantage preservation at operative level with consequent stress reduction levels.We compared function, radiographic measures, incidence complications 3-year followup after Bryan(®) prosthesis ACDF patients myelopathy.Eighty-three myelopathy were randomized to undergo implantation a (n = 41) or 42). Patients assessed preoperatively 3 years postoperatively using modified Odom's criteria, Japanese Orthopaedic Association scale, SF-36, Neck Disability Index. ROM, stability, subsidence prostheses evaluated radiographically.Patients who received scored significantly better three four functional assessment methods used (Japanese Index). ROM was retained by group but not group. had fewer complications, primarily because dysphagia occurred only one patient seven Other included pseudarthrosis spontaneous fusion, deep vein thrombosis, heterotopic ossification group.Bryan(®) appears reliable effective myelopathy.Level II, therapeutic study.
