This study is aimed to determine and validate the therapeutic value and long-term effects of transforaminal dorsal root ganglion(DRG) andepidural block in patients with refractory back and radicular leg pain due to herniated lumbar disc disorders.
Patients who met our inclusion criteria received the fluoroscopy guided, transforaminal DRG and epidural blockstargeted directly at the level and side of their documented pathology. Patients were evaluated by an independent observer and received sequential questionnaires before and after injection to document level of pain, level of activity, and amount of satisfaction.
Two hundred and fifty-four patients met our inclusion criteria and were followed for a minimum period of 6 months(average 35 weeks, range 24-50 weeks). Two hundred and twenty-one(87.0%) had a successful long-term outcome, reporting at least a 50% reduction between pre- and post-injection pain scores, and were able to return to or near to their previous levels of functioning after an average of 2.2 injections(range 1-3). Onlynine(3.5%) of the remaining 33 patients underwent an operation. Twenty-four patients showed recurrence of symptoms, but obtained beneficial effects, similar to earlier blocks, from subsequent injections. Of our patients, 85.0% were satisfied with their outcomes. There was no worsening of symptoms or complications from the procedures.
The fluoroscopy guided transforaminal DRG and epidural blocks appear to be an effective nonsurgical treatment option for patients with lumbar herniated nucleus pulposus and radiculopathy for whom conservative treatments are not effective, and should be considered before surgical intervention.
