Background:
Various minimally invasive surgeries were proposed for the management of herniated lumbar intervertebral disc. However, to choose optimal treatment modality to maximize patient benefit is a clinical challenge for the treatment givers.
Objective:
The objective was to study the role of ozone disc nucleolysis in the management of herniated lumbar intervertebral disc by retrospective analysis.
Methodology:
We conducted a retrospective analysis of patients of lumbar disc herniation treated by ozone disc nucleolysis during May 2007-May 2021. There were total of 2089 patients with 58% of males and 42% of females. The age ranged from 18 to 88 years. Outcome was measured on the Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI) along with modified MacNab method.
Results:
The mean baseline VAS score was 7.73, which became 3.07 at 1 month, 1.44 at 3 months, 1.42 at 6 months, and 1.36 at 1 year. Similarly, the mean ODI index was 35.92 at baseline, which improved to 9.17 at 1 month, 6.14 at 3 months, 6.10 at 6 months, and 6.09 at 1 year. VAS score and ODI analysis was found to be statistically significant with P < 0.05. Modified MacNab criterion showed successful treatment outcome in 85.6% with excellent recovery in 1161 (55.58%), good recovery in 423 (20.25%), and fair recovery in 204 (9.77%). Mediocre or no recovery was seen in the remaining 301 patients amounting to a 14.40% failure rate.
Conclusion:
This retrospective analysis confirms that ozone disc nucleolysis is an optimally effective and least invasive treatment option for herniated lumbar intervertebral disc with a significant reduction in disability.
