Effectiveness of ozone nucleolysis in alleviating pain and enhancing function in lumbar sciatica due to disc herniation: a minimally invasive approach.

OBJECTIVES

Ozone (O-O) nucleolysis is emerging as a promising minimally invasive therapy for treating lumbosciatica due to herniated discs. This study aims to evaluate changes in pain and functional abilities before and after ozone disc nucleolysis in patients with lumbar disc herniation (LDH).

MATERIALS AND METHODS

This study included 34 patients (15 males, 19 females; age range 17-76, average age 46.7 ± 11.2 years) treated between April 2018 and May 2022. A single dose of an O-O mixture (5 ml, 30 µg/ml) was injected into the disc under fluoroscopic guidance via a lateral approach, followed by an additional periradicular injection of the same mixture (5 ml) combined with a corticosteroid (2 ml). Pain and patient satisfaction were assessed using the VAS score and modified MacNab criteria, while MRI findings evaluated treatment-related changes, including herniated disc surface and disc height.

RESULTS

VAS scores indicated pain improvement in 85% of patients, with 82% achieving satisfactory outcomes per modified MacNab criteria. Patients under 50 years of age showed greater responsiveness to ozone therapy. Central LDH responded more favorably than larger foraminal herniations, and hernias with a larger surface area than the average also showed better outcomes. No complications were observed.

CONCLUSION

Ozone therapy is a cost-effective, simple, and safe minimally invasive technique that provides significant pain relief and functional improvement. It may be a reliable and competitive treatment option for patients with persistent symptoms after conservative treatment and before considering surgical intervention. Key Points •Ozone nucleolysis provides a minimally invasive treatment for lumbosciatica with reduced recovery time. •Injecting oxygen-ozone into the disc decreases its volume and inflammation, easing nerve pressure. •Initial results show significant pain relief and improved mobility in patients following treatment. •This method appears safe, with fewer complications than traditional surgery for herniated discs.
