Comparison of biomechanical properties of cervical artificial disc prosthesis: a review.
Cervical artificial discs are frequently implanted. Clinical data are frequently presented. However, biomechanical data are scarce. The literature is extensively reviewed following general rules for systemic review. The manufacturers of cervical artificial discs are requested for information. Only 10 articles were suitable for review. Together with some information of the manufacturer, data of 5 out of 8 discs can be provided. Comparison is not possible since testing methods differ. Before introduction of a new device biomechanical data should be provided. This should be done after standardized testing and presentation of the results. Only then comparison is possible as is a responsible choice for our patients.
