Dynesys, a pedicle-based dynamic stabilization system, was introduced to overcome some undesirable complications of fusion procedures. Nevertheless, the theoretical advantages of Dynesys over fusion have not been clearly confirmed. The purpose of this editorial was to compare clinical and radiological outcomes of patients who underwent Dynesys system with those who underwent posterior lumbar fusion according to the existing literature and to see if the application of the Dynesys system is superior to the traditional lumbar fusion surgery. According to published clinical reports, the short-term effects of the Dynesys dynamic stabilization system are similar to that of traditional lumbar fusion surgery. Three comparative studies of Dynesys dynamic stabilization and fusion surgery with medium-term follow-up are encouraging. However, the results from four single-treatment-arm and small-sample studies of case series with long-term follow-up were not encouraging. In the present circumstances, it is not possible to conclude that the Dynesys dynamic stabilization system is superior to fusion surgery for lumbar degenerative diseases.
