ObjectiveThe objectives of this study were to clarify the short-term effects of transforaminal epidural steroid injection (TFESI) for degenerative lumbar scoliosis combined with spinal stenosis (DLSS), and to extrapolate factors relating to the prognosis of treatment.MethodThirty-six patients with lumbar radicular pain from DLSS were enrolled. Subjects were randomly assigned to one of two groups (steroid or lidocaine group). We compared the effect of pain suppression at 2, 4 and 12 weeks after the procedure between the two groups. Radiographic analysis included measurement of the Cobb's angle, the upper endplate obliquities of L3 and L4, and maximal lateral olisthy between two adjacent lumbar vertebrae. Sagittal plane measurement included lumbar lordosis, and thoracolumbar kyphosis. Statistical analysis of both radiographic and clinical parameters along with treatment outcome was performed to determine any significant correlations between the two.ResultsThere were no significant differences in the demographic data, initial visual analogue scale (VAS) or Oswestry disability index (ODI) between the steroid group (n=17) and the lidocaine group (n=19). Two, 4, and 12 weeks after injection VAS, ODI showed a significantly greater improvement in the steroid group compared to the lidocaine group (p<0.05). The radiographic and clinical parameters were not significantly correlated with treatment outcome.ConclusionOur findings suggest that fluoroscopic transforaminal epidural steroid injections appear to be an effective non-surgical treatment option for patients with degenerative lumbar scoliosis combined with spinal stenosis (DLSS) and radicular pain.
