Yang X, et al. - Experts reviewed the current literature on the comparison of the radiological outcome of cervical arthroplasty with fusion after anterior discectomy for radiculopathy. Nonetheless, an introduction of the cervical disc prosthesis was done to decrease adjacent level disease, convincing radiological evidence for this benefit was lacking. Authors noted that there were insufficient studies on the heterotopic ossification as a complicating factor in the preservation of motion of the device. Currently, no firm conclusion can be drawn regarding purely radiological outcomes for implanting cervical prosthesis vs performing fusion.
