All

Inclusion criteria

Inclusion criteria: - age =20 years old - pain intensity =5 out of 11 on the numerical rating scale (NRS) - chronic LRP lasting =12 weeks - previous failure of conservative management such as physiotherapy, exercise therapy, or analgesic medications - lumbar spinal stenosis was confirmed on magnetic resonance imaging (MRI) All eligible patients received conventional fluoroscopy-guided transforaminal epidural injection with local anesthetics and steroid before enrollment. Patients who demonstrated no pain reduction (NRS score =5) following epidural injection were finally enrolled.

Exclusion criteria

Exclusion criteria: - patient refusal - age 9–points on NRS, pain <4–points on NRS - acute pain of onset lasting <12 weeks - signs of progressive motor weakness or neurologic deficits - allergies to steroids or contrast dyes - coagulopathy - epidural steroid injection within the previous 4 weeks - systemic infection, injection site infection - malignancy

Design outcomes

Primary

MeasureTime frame
number of successful responders to treatment in each group at the 3-month follow-up period. Successful response was defined as: 1) =50% or 4-point reduction in the NRS pain intensity (or) 2) 10-point decrease in ODI, or mean score =6 points on the GPE scale

Secondary

MeasureTime frame
NRS pain intensity at 1, 2 4, 12 weeks and ODI scores at 4, 12 weeks post-procedure
