Factors associated with transforaminal epidural steroid injection efficacy and prognosis for symptomatic treatment of lumbar stenosis associated with degenerative scoliosis

This study, the first of its kind, suggests that for symptomatic treatment of axial and radicular pain in the treatment of degenerative lumbar scoliosis associated with stenosis, TFESIs performed on the convex side of the primary lumbar scoliosis curve provide more symptomatic relief than concave side injections in treating radicular pain in general including at the L5-S1 level and that a history of symptom relief from TFESI is a positive predictor of outcomes for future lumbar surgery.
