ABSTRACT: Background: Artificial
cervical disc replacement has become an option for cervical radiculopathy.
Previous studies have evaluated the efficacy of this alternative without the
scientific rigor of a concurrent control population in oriental patients for
long-term follow-up. Objective: Therefore, we asked whether the 1) clinical and
2) radiographic outcomes of Bryan cervical disc prosthesis were better than
that of anterior cervical discectomy and fusion (ACDF) at single site, and
whether the 3) occurrences of heterotopic ossifications (HOs) were associated
to the function loss in the long-term follow-up. Methods:A total of 120 patients with
cervical disc disease were randomly assigned to two groups (Bryan or ACDF), and
60-month follow-up is available for all the 120 patients. Clinical outcomes
were assessed using Odom’s criteria, visual analogue pain scale (VAS) and Neck
Disability Index (NDI). Radiographs were measured to determine the radiographic
outcomes and occurrences of heterotopic ossifications (HOs).Results: The clinical outcomes
are not significantly between the two groups (VAS, P = 0.7253; NDI, P =
0.5528). The radiographic outcome ofBryancervical disc prosthesis is better
than that of ACDF group at the index level (P
