Background: Artificialcervical disc replacement has become an option for cervical radiculopathy.Previous studies have evaluated the efficacy of this alternative without thescientific rigor of a concurrent control population in oriental patients forlong-term follow-up. Objective: Therefore, we asked whether the 1 clinical and2 radiographic outcomes of Bryan cervical disc prosthesis were better thanthat of anterior cervical discectomy and fusion ACDF at single site, andwhether the 3 occurrences of heterotopic ossifications HOs were associatedto the function loss in the long-term follow-up. Methods: A total of 120 patients withcervical disc disease were randomly assigned to two groups Bryan or ACDF, and60-month follow-up is available for all the 120 patients. Clinical outcomeswere assessed using Odom’s criteria, visual analogue pain scale VAS and NeckDisability Index NDI. Radiographs were measured to determine the radiographicoutcomes and occurrences of heterotopic ossifications HOs. Results: The clinical outcomesare not significantly between the two groups VAS, P = 0.7253; NDI, P =0.5528. The radiographic outcome ofBryancervical disc prosthesis is betterthan that of ACDF group at the index level P < 0.05. 36 60% patientsofBryangroup developed heterotopic ossification. But, there is not asignificant association between HOs and the loss of movement at the replacementlevel. Conclusions: The Bryan artificial disc replacement compares favorably toACDF for the treatment of patients with 1-level cervical disc disease. AndtheBryandisc may delay adjacent level degeneration by preserving preoperativekinematics at adjacent levels in oriental patients.
