Background: Spinal stenosis and herniated intervertebral discs are the principal causes of lumbosacral
radiculopathy. This study was conducted to compare the therapeutic value and duration of pain relief of
fluoroscopic guided transforaminal epidural steroid injections (TFESIs) in patients with refractory radicular leg pain.
Methods: Between August 2006 and March 2007, 87 patients (H group: patients with herniated intervertebral
disc, S group: patients with spinal stenosis) who met the inclusion criteria were treated with fluoroscopic guided
TFESIs. Prior to treatment, the VAS and ODI scores were determine to evaluate the degree of pain and level
of disability. The degree of pain relief was then assessed 1 month after treatment with the TFESIs and graded
as excellent (no residual pain), good (improvement of pain symptoms by more than 50%), fair (improvement of
pain symptoms by less than 50%) and Poor (no improvement of pain). In addition, the duration of pain relief
was evaluated by regular outpatient visits for 6 months, and by telephone interviews after 6 months.
Results: The H and S group both had excellet results at 1 month after treatment with TFESIs showing
improvements of 44.1% and 20.8% respectively. However this difference was not significant between groups.
In addition, a duration of pain relief greater than 6 months was achieved in 32.4% of the patients in the H group
and 37.7% of those in the S group.
Conclusions: TFESIs had a similar degree of therapeutic effectiveness and duration of pain relief in patients
with spinal stenosis and herniated intervertebral discs. (Korean J Pain 2008; 21: 38?43)
