OBJECTIVE: Transforaminal epidural steroid injection (TESE), which is one of the minimally invasive procedures in lumbar disc herniations (LDH), can significantly reduce the pain of patients. In our study, it was aimed to evaluate the efficacy of TESE in patients with radiculopathic symptoms and single-distance LDH who did not undergo surgery. MATERIAL AND METHODS: Medical records of patients who underwent TESE between 2007 and 2011 were reviewed retrospectively. Visual analog scale (VAS), straight leg lift (DBK) test, and patient satisfaction scores were evaluated before and after the TESE procedure in the first 6 months of follow-up. RESULTS: 105 patients (21 men, 84 women) were evaluated. When the control VAS and DBK test values were compared with the pre-intervention values, and significant improvements were detected. The 1st, $3^{rd}, and 6^{th}$-month control VAS values of the cases were found to be significantly lower than the pre-intervention VAS values (p<0.001). It was observed that there was a statistically significant improvement in the 1st, $3^{rd}, and 6^{th}$-month DBC test values of the cases compared to the pre-intervention DBC test values (p<0.001). According to the pre-interventional VAS, 85.71% success was achieved in the 1st -month control VAS, 87.62% success in the 3rd month VAS and 47.62% in the 6th month VAS. After TESE, patient satisfaction was 95.2% in the 1st month, 93.3% in the $3^{rd}$ month, and 86.7% in the $6^{th}$ month. CONCLUSIONS: TESE is a minimally invasive method that can be applied in radiculopathic pain due to LDH.
