Abstract | OBJECTIVE: MATERIALS AND METHODS: A total of 200 patients were included in the study and were followed for a minimum of 6 months. In our series, we treated 80 postero-lateral herniated discs (40% of cases), 46 postero-medial herniated discs (23%), and 74 foraminal herniated discs (37%). Level L3-L4 was treated in 30 cases (15%), L4-L5 in 98 cases (49%), and L5-S1 in 72 cases (36%). The procedure was performed under dual guidance: fluoroscopic and CT. A helical probe was activated. It penetrates the herniated disc and causes the pulpous material to be mechanically evacuated through the probe. All 200 patients were followed for a minimum of 6 months. RESULTS: In group 1, the patients had a mean pain score of 7.9 ± 2.5 VAS units (range 6-10 units) prior to intervention. This was reduced to 3.2 ± 2.1 VAS units (range 0-10 units) at 48 h follow-up and increased to 3.9 ± 1.2 VAS units (range 0-10 VAS units) at 1 month follow-up and further reduced to 2.7 ± 1.2 units (range 0-10 VAS units) at 6 month follow-up. In group 2, the patients had a mean pain score of 8.2 ± 3.2 VAS units (range 6-10 units) prior to intervention. This was reduced to 2.8 ± 1.5 VAS units (range 0-10 units) at 48 h follow-up and decreased to 1.5 ± 0.9 VAS units (range 0-10 units) at 1 month and further reduced to 1.1 ± 0.5 VAS units (range 0-10 units) at 6 months. CONCLUSION: Our study showed that results were more satisfactory for the hernia located laterally (postero-lateral, foraminal, and extra-foraminal) as compared to the hernia located posteromedially.
