One-year follow-up results of intradiscal diode laser, radiofrequency, and pulsed radiofrequency therapies: a retrospective study

Abstract

This study aims to investigate the efficacy of three different percutaneous intradiscal therapies in patients with chronic low back pain (CLBP) due to lumbar disc herniation (LDH). Medical files of a total of 120 patients who received percutaneous intradiscal therapy were retrospectively analyzed. All patients were divided into three groups: group L: diode laser (n = 40), group R: radiofrequency (RF) (n = 40), and group P: pulsed radiofrequency (PRF) (n = 40). The visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores were calculated at 1, 3, 6, and 12 months for all patients. One-year follow-up results were as follows: group L: pre-treatment (PreT) VAS 5.6 ± −1, ODI 37.6 ± −4.7, post-treatment 12th month (PT12) VAS 2.8 ± −1.4, ODI 14.1 ± −7.1; group P: PreT VAS 6.0 ± 1, ODI 37.5 ± 5.9, PT12 VAS 3.1 ± 1.3, ODI 20.3 ± 17.0; and group R: PreT VAS 5.6 ± 1.0, ODI 37.9 ± 4.7, PT12 VAS 3.3 ± 1.4, ODI 27.2 ± 14.1. In each of the three groups, there was a statistically significant reduction in the VAS and ODI scores at 1, 3, 6, and 12 months, compared to the baseline values (p < 0.05). The highest reduction in the VAS and ODI scores was observed in group L, whereas the lowest reduction was in group R. We consider that in groups with patient selection criteria at our study; diode laser, RF, and PRF, which are administered using the percutaneous intradiscal route for CLBP patients diagnosed with LDH, may be used as an alternative treatment option.
