Comparative effectiveness of paravertebral Ozone injection and caudal epidural steroid-hyaluronidase injection in lumbosacral spinal stenosis

Lumbosacral spinal stenosis (LSS) is the narrowing of the lumbar spinal canal. LSS usually happens in older people who do not have the proper physical condition to undergo surgery. Therefore, minimally invasive methods such as Ozone therapy and epidural injection can be used in these patients.The objective this study was to compare the effect of caudal epidural steroid-hyaluronidase injection with paravertebral intramuscular Ozone injection on reducing pain in patients with LSS.A total of 30 patients suffering from LSS randomized to two groups. Group A (Within-group changes showed significant improvement in VAS, ODI, RMQ, and QBPDS scores in both groups from pre-treatment to end of follow-up (allBoth intramuscular injection Ozone and caudal epidural injection steroid- hyalaz significantly reduce pain. The existing data suggested 8 weeks improvements in pain severity are more significant for paravertebral Ozone injection, compared to caudal epidural steroid-hyaluronidase injection.
