Unintended facet fusions after Dynesys dynamic stabilization in patients with spondylolisthesis.

CONCLUSIONSDuring the mean follow-up of almost 4 years, the prevalence of unintended facet arthrodesis was 52.1% in patients who underwent DDS. Although the clinical outcomes were not affected, elderly patients with spondylolisthesis might have a greater chance of facet fusion. This could be a cause of the limited range of motion at the index levels long after DDS. PMID: 30544347 [PubMed - as supplied by publisher]
