A prospective, randomized double-blind multicenter trial among patients with cervical radiculopathy due to single-level disc herniation was conducted. Patients were randomly assigned into three groups: anterior cervical discectomy with arthroplasty (ACDA; activC, Aesculap AG, Tuttlingen, Germany), anterior cervical discectomy with fusion (ACDF; Cage standalone) and anterior cervical discectomy without fusion (ACD). The design and study protocol were published previously.13 (link) The protocol was approved by medical ethics committees, including an approval for randomization after anesthetic induction. All patients gave informed consent. The 2-year follow-up data revealed no differences in clinical outcomes.14 (link)
