Radiofrequency denervation of the zygapophysial (facet) joints is a frequently performed procedure for chronic low back pain. However, cryoablation represents a novel therapeutic approach for this condition. We observed and analyzed 3 cases with confirmed positive lumbar facet joint syndrome. Our results show a significant improvement in the clinical state of the patients in the first and third months after the procedure. The 6-month follow-up examination demonstrates a recurrence of pain and a gradual deterioration in the quality of life with a lasting partial pain-relief effect. Thermal radiofrequency denervation and cryoablation of the lumbar zygapophysial joints represent an effective, albeit temporary treatment option for lumbar facet joint syndrome patients, resulting from the pathophysiology of sensory nerve regeneration after destructive procedures. This type of treatment can be used repeatedly in the case of a positive response.
