Objective: To determine the efficacy of transforaminal epidural steroid injection (TFESI) using conventional versus Kambin’s triangle approaches in patients of lumbar radiculopathy. Study Design: Quasi experimental study. Place and Duration of Study: Department of Pain Medicine, Combined Military Hospital Rawalpindi Pakistan, from Oct 2019 to Apr 2020. Methodology: Eighty patients suffering from lumbar radiculopathy fulfilling the inclusion criteria were included in this study and were randomly assigned to undergo transforaminal epidural steroid injection using either conventional approach (group C) or the Kambin’s triangle (group K) approach. Pain scores and patient satisfaction levels were recorded at 4 and 8 weeks after the procedure. Results: In both groups, the pain score (group C pre-procedure NRS =7.28 ± 1.26 vs post-procedure NRS = 2.14 ± 0.81, group K pre-procedure NRS = 7.33 ± 1.16 vs post-procedure NRS=2.70 ± 0.94) and patient satisfaction improved 4 and 8 weeks after the procedure. The pain score (p-value=0.21) and patient satisfaction score (p-value=0.88) however were not significantly different between groups. Conclusion: This study demonstrated that using conventional or Kambin’s approach exhibits no difference in decreasing pain score or patient satisfaction level.

Abstract Objective To investigate the impact of contrast dispersion pattern/location during lumbar CT-guided transforaminal epidural steroid injection (TFESI) and experience of the performing radiologist on therapeutic outcome. Materials and methods In this single-center retrospective cohort study, two observers analyzed contrast dispersion during CT-guided TFESI of 204 patients (age 61.1 ± 14 years) with discogenic unilateral single-level L4 or L5 radiculopathy. The contrast dispersion pattern was classified as “focal,” “linear,” or “tram-track”; the location was divided into “extraforaminal,” “foraminal,” or “recessal.” Pain was assessed before and 4 weeks after treatment using a numerical rating scale (0, no pain; 10, intolerable pain). Additionally, the patient global impression of change (PGIC) was assessed. The TFESI was performed by musculoskeletal radiologists (experience range: first year of musculoskeletal fellowship training to 19 years). Contrast pattern/location and radiologist’s experience were compared between “good responder” (≥ 50% pain reduction) and “poor responder” (< 50%). A p-value < 0.05 was considered to be statistically significant. Results Overall, CT-guided TFESI resulted in a substantial pain reduction in 46.6% of patients with discogenic radiculopathy. The contrast dispersion pattern and location had no effect on pain relief (p = 0.75 and p = 0.09) and PGIC (p = 0.70 and p = 0.21) 4 weeks after TFESI. Additionally, the experience of the radiologist had no influence on pain reduction (p = 0.92) or PGIC (p = 0.75). Regarding pre-interventional imaging findings, both the location and grading of nerve compression had no effect on pain relief (p = 0.91 and p = 0.85) and PGIC (p = 0.18 and p = 0.31). Conclusion Our results indicate that neither contrast agent dispersion/location nor the experience of the radiologist allows predicting the therapeutic outcome 4 weeks after the procedure.

BackgroundLumbosacral radicular pain (LSRP) can be caused by disc herniation, spinal stenosis, and failed back surgery syndrome. The clinical effect of pulsed-radiofrequency (PRF) combined with transforaminal epidural steroid injection (TESI) for radiating pain in different population remains unclear.MethodsWe retrospectively reviewed the medical recordings of patients with LSRP caused by different etiologies, who underwent PRF and TESI treatment. The primary clinical outcome was assessed by a 10-point Visual Analog Scale (VAS) pre- and post-treatment.ResultsA total of 34 LSRP patients were identified and classified into 3 subgroups (disc herniation, spinal stenosis, and failed back surgery syndrome). The overall immediate pain reduction was 4.4 ± 1.1 after procedure. After a median follow-up of 9.5 months, the VAS decreased from 6.5 ± 1.0 to 2.4 ± 1.9 at the last follow-up.ConclusionPRF combined with TESI is an effective approach to treat persistent LSRP in distinct population.

BACKGROUND: Transforaminal epidural steroid injection (TFESI) is an interventional technique used to relieve disc herniation related back and radicular pain. Although few studies have investigated the factors predicting positive outcomes after TFESI, there is no data concerning the possible relationship between pre-procedure serum 25-hydroxyvitamin D (25(OH)D) levels and the response to TFESI. OBJECTIVES: To investigate the effect of vitamin D deficiency to treatment success of fluoroscopy-guided transforaminal epidural steroid injection. STUDY DESIGN: A retrospective assessment. SETTING: A university hospital interventional pain management center. METHODS: Nine hundred forty-eight patients received lumbosacral TFESI between January 2018 and December 2019 in a university hospital pain management center and were examined retrospectively for eligibility. Clinical and demographic data; magnetic resonance imaging (MRI); pre-procedure laboratory tests, including serum 25(OH)D; pain scores at baseline, third week, and third month follow-ups were collected. RESULTS: A total of 83 patients were recruited and divided into 2 groups with respect to vitamin D status. The number of patients with serum 25(OH)D level below 20 ng/mL was 57 and the number of patients with serum 25(OH)D level above 20 ng/mL was 26. Treatment success rates were significantly lower in vitamin D deficient group at third week and third month (P: 0.006, P: 0.01). LIMITATIONS: Retrospective nature and the absence of functional outcomes. CONCLUSION: Vitamin D deficiency is associated with a lower probability of meaningful pain relief following TFESI. It may worth assessing serum vitamin D level prior to this intervention, although prospective investigation is necessary.
