Abstract
Objective
The aim of this study was to prospectively evaluate the clinical efficacy of perigangliar steroid and local anesthetic with intradiscal O2–O3 injection versus steroid and local anesthetic intraforaminal injection in different types of herniation and grade of disc degeneration.
Materials and methods
A total of 517 patients were randomly assigned to two groups. Control Group (159 men, 101 women; age range 25–89 years) underwent steroid and local anesthetic intraforaminal injection. Study Group (163 men, 94 women; age range 22–92 years) underwent the same treatment with addiction of O2–O3 intradiscal injection. Procedures were performed under computed tomographic guidance. Visual Analog Scale Questionnaire was administered before treatment and at intervals, the last at 6-month follow-up. Results were compared with Kruskal–Wallis and t test.
Results
After 6 months, O2–O3 discolysis was successful in 106 (41.24 %) Study Group patients with extrusions compared with 9 Control Group patients (3.5 %) (P < 0.001). In 89 (34.6 %) Study Group patients with protrusions, success rate was statistically significant compared with 5 Control Group patients (1.9 %). Significant difference was detected in the presence of Grade I, II, III of Degenerated Disc in 185 of Study Group patients (68.4 %) compared with 4 Control Group patients (1.5 %).
Conclusions
The addition of O2–O3 discolysis is more effective at 6 months than perigangliar steroid and local anesthetic injection, especially in cases of herniated or protruded discs and with a Grade of Disc Degeneration from mild to moderate range.
