摘要

Background

Lumbar disc herniation (DH) is a prevalent condition, with transforaminal epidural steroid injections (TFESI) widely used to manage associated radicular pain. Despite its common use, the predictive value of various clinical and imaging characteristics, particularly the location of LDH, on TFESI outcomes remains unclear.

Objectives

This review evaluates the influence of LDH location and other imaging or clinical predictors on TFESI efficacy, hypothesizing that more lateral herniations may be associated with better treatment outcomes.

Study Design

A systematic review of 13 studies analyzing TFESI outcomes in patients with LDH was conducted.

Setting

Ambulatory or outpatient setting.

Methods, Patients, Intervention, Measurement

Articles included patients undergoing TFESI monotherapy for pain management due to lumbar DH. Studies assessing disc morphology, herniation location (central, paracentral, foraminal, extraforaminal), and/or nerve root compression were reviewed. Outcome measures included Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and other validated pain/disability indices.

Results

Three studies reported significantly better outcomes for lateral herniations (foraminal, extraforaminal), while six studies found no significant difference by location. Two studies suggested better outcomes in central herniations. Mild nerve compression, positive Slump test findings, and optimal TFESI technique correlated strongly with favorable outcomes. Severe nerve compression and technical challenges with more lateral herniations negatively impacted efficacy.

Limitations

Heterogeneity in study design, outcome measures, and follow-up intervals limited generalizability. Many studies lacked control groups or long-term follow-up. Additionally, most of the included studies used particulate steroids.

Conclusion

LDH location influences TFESI response, with mild compression and lateral herniations generally yielding favorable outcomes. However, technical proficiency and clinical predictors, such as positive Slump test, may be stronger determinants of success than herniation location alone. Further standardized research is required to optimize patient selection and elucidate the prognostic factors that contribute to TFESI treatment response.
