In Brief Study Design. Randomized controlled study. Objective. To compare the rates of adverse events associated with disc arthroplasty versus those anterior cervical discectomy and arthrodesis allograft plate. Summary Background Data. Cervical as a substitute for fusion has been developed to maintain motion and, theoretically, prevent adjacent segment degeneration. Currently, devices are undergoing clinical testing safety efficacy. The evaluation is performed by critical analysis all occurrences following surgery determine if new device beneficial risk profile patient. Methods. Adverse Bryan Disc were compared in prospective randomized Four hundred sixty-three (463) patients having radiculopathy or myelopathy at single level treated 31 sites. A total 242 received 221 had fusion. All evaluated before 1.5, 3, 6, 12, 24 months after surgery. recorded concurrently categorized severity medically surgically related. Results. No differences overall medical occurred between groups. Surgically related more frequently investigational group secondary complaints postoperative dysphagia late patients. However, severe World Health Organization Grade 3 4 treatment pseudarthrosis persistent symptoms. Significantly, spine reoperations group. Only one spinal cord injury it was no deep infection death either procedure. Conclusion. replacement both safe procedures low incidence significant Statistically, serious while greater number less seen study that Minimal Both
